WRS’s Pulsation Dampeners are designed to reduce pulsation and vibration in the pipe system that is caused by a metering pump or plunger pump. It ensures a smooth and continuous flow of the system. By removing the pulsation flows, the efficiency and accuracy of the pump system can be increase significantly. On the other hand, it helps to protect the pump, seals, gaskets of the entire systems from vibration and result in a longer lasting safer system. Compressed air or gas is introduced into the air chamber of the Pulsation Dampener to a specified pressure. The gas is entrapped by the elastomeric bladder, which prevents contact between the process fluid and compressed gas. During pump discharge, fluid enters the wetted chamber of the WRS Pulsation Dampener, displacing the bladder, compressing the gas and absorbing the shock. During pump shift, liquid pressure decreases, the dampener gas expands, pushing fluid back into the process line. Whether a piston, plunger, air diaphragm, peristaltic, gear, or diaphragm metering pump a WRS Pulsation Dampener placed at the pump’s discharge will produce a steady fluid flow up to 99% pulsation free; protecting the entire pumping system from the damaging effects of shock.

They are ideal for dosing chemicals, aerating water, dosing ozone and fertigation without additional pump. Venturis work on a principle of differential pressure. In short, water flows into the Venturi at a higher pressure than that at which it exits. This pressure difference creates a vacuum at the suction port on the side of the device. This sucks air, ozone or liquid into the main water stream. So, the greater the difference in pressure, the greater the vacuum and, with that, the greater the efficiency of mixing.

Static mixers create stable emulsions because they reduce the particles to a smaller size so they stay together in a stronger bond for a longer period of time. In general, static mixers work by dividing streams of ingredients that need to be mixed. The ingredient stream typically is forced through the static mixer by a pump. The ingredients then are split into substreams as they are forced through the mixer. These substreams then are recombined and divided once again. This process might be repeated numerous times.

It is also referred as pressure relief valve in the industry. Safety valve helps to prevent system being over pressure. In a typical setup, it shall be installed along the return pipeline after the metering pump. While installing a safety valve, it shall be installed as close as possible towards the dosing pump and there shouldn’t be any valve in between. When the pressure in the system pipeline exceeds the preset value, the diaphragm and the shaft are jacked up, and the medium is discharged back to the return pipe. The preset value can be adjusted directly on the safety valve itself. The preset value can be adjusted within 0 – 1Mpa by adjusting the adjustable nut. The relief pressure is generally set higher than the system pressure by 0. 1-0. 2Mpa and not exceeding the maximum pressure of the metering pump. Back pressure valve is very similar to safety valve, but the emphasis is on steady state pressure control instead of on/off actuation. It shall be installed on the positive pressure side along the discharge pipe of the metering pump. A back-pressure valve can prevent the occurrence of siphoning and reduce unstable dosage which is caused by the pressure fluctuation.

What is a Solenoid Driven Dosing Pump? A dosing pump, also commonly known as metering pump or chemical injection pump. It is categorized under positive displacement pump family. The main purpose of a dosing pump is to accurately dose chemical into a system. There are various type of dosing pump such as piston, peristaltic, diaphragm and hydraulic diaphragm. ML & ML-S dosing pump is a microprocessor-controlled solenoid diaphragm type dosing pump. How does it work? Solenoid metering pump is the use of electromagnetic push rod driven diaphragm in the pump head reciprocating movement, causing the pump head chamber volume and pressure changes. Changes in pressure caused by suction valve and discharge valve opening and closing, to achieve quantitative liquid suction and discharge. A magnet moves the solenoid shaft forwards and backwards by switching on and off. This stroke movement is transferred to the diaphragm in the dosing head. Two non-return valves prevent the feed chemical from flowing back during pumping. But that's not all. The stroke length and stroke rate can be adjusted to alter the capacity of... --- > Motor Driven Chemical Dosing Pump.

Among the many tools designed to achieve accuracy and reliability, the peristaltic dosing pump stands out as one of the most adaptable and efficient. This pump has earned a reputation for its simple design, hygienic operation, and ability to handle a wide variety of liquids. Therefore, in this article, we will examine how peristaltic dosing pumps operate, their key advantages, common applications, and why they are an ideal choice for industries where consistency and cleanliness are paramount. What Is a Peristaltic Dosing Pump? A peristaltic dosing pump is a type of positive displacement pump that operates by compressing and releasing a flexible tube or hose. Inside the pump, rotating rollers or shoes squeeze the tubing in sequence, pushing fluid forward in a controlled manner. Once the roller passes, the tubing rebounds to its original shape, creating suction that draws in more liquid. This repeating action mimics the natural peristalsis that occurs in biological systems, such as the human digestive tract. Unlike other pumps that rely on seals, valves, or diaphragms, a peristaltic dosing pump only comes into contact with the fluid through the tubing itself. This design greatly reduces contamination risks and makes the pump exceptionally versatile for sensitive or aggressive liquids. Key Features and Benefits The popularity of peristaltic dosing pumps comes from several clear advantages: 1. Accurate and Repeatable Dosing These pumps deliver precise, reliable doses, maintaining exact fluid volumes with each rotation. Their consistent displacement ensures trusted... --- > A solenoid pump is a compact and precise positive displacement pump used in water treatment, food, pharmaceuticals, agriculture, and chemical dosing. - Published: 2025-09-18 - Modified: 2025-09-18 - URL: https://wrsdosing.com/chemical-dosing-pump/an-in-depth-guide-to-solenoid-pumps-in-modern-applications/ - Categories: Chemical Dosing Pump, knowledge, Metering Pumps - Tags: Chemical Dosing Pumps, Dosing Pumps, Solenoid Dosing Pump Industries today need fluid handling systems that are precise, efficient, and durable. Solenoid pumps are a reliable solution, used in areas like water treatment, lab analysis, food processing, and chemical dosing. This article explains how solenoid pumps work, their benefits and drawbacks, and where they are most commonly used. What Are Solenoid Pumps? A solenoid pump is a type of positive-displacement pump. It utilizes the electromagnetic force generated by a solenoid coil to create a pumping action. Unlike centrifugal pumps that rely on rotation, solenoid pumps use linear motion. When electricity passes through the solenoid coil, it creates a magnetic field that causes a plunger or diaphragm to move forward. This motion displaces fluid and pushes it through the outlet. When the current stops, a spring or reverse force resets the plunger, drawing more liquid into the chamber. This simple yet effective mechanism makes solenoid pumps highly efficient for dosing and metering applications where precise control is essential. Key Features of Solenoid Pumps Solenoid pumps stand out for several distinct features: 1. Precise Dosing and Metering Because solenoid pumps operate with controlled strokes, they can deliver exact volumes of liquid repeatedly. This makes them ideal for applications requiring consistent and reliable dosing. 2. Compact Design Their relatively small size allows solenoid pumps to be easily integrated into systems with limited space, such as laboratory instruments or compact treatment units. 3. Energy Efficiency Since they only consume energy during each stroke and have no continuously rotating components, solenoid pumps are energy-efficient,... --- > Chemical dosing pumps inject precise amounts of chemicals into systems.

They ensure safety, improve efficiency, and are used in water treatment, agriculture, food, pharmaceuticals, and industry. Keyword: chemical dosing pumps ===================================================== Chemical dosing pumps are essential in industries that need precise chemical delivery. While standard pumps move large volumes, dosing pumps add small, measured amounts to specific systems. This helps control processes, improve safety, and protect equipment in water treatment, agriculture, and pharmaceuticals. More than that, automation makes the process more reliable and reduces waste. What is a Chemical Dosing Pump? A chemical dosing pump is designed to inject precise amounts of a chemical into a fluid stream, tank, or system. It delivers small, controlled quantities at set rates and intervals. Thus, it is vital in industries where the right chemical balance ensures safety, efficiency, and product quality. The working principle is straightforward: a dosing pump draws chemical solution into its chamber during the suction phase and pushes it into the target system during discharge, all at a controlled rate. Modern pumps allow for manual or automatic flow control and can connect to sensors for real-time adjustments based on variables such as pH or concentration. Chemical dosing pumps are widely used in water and wastewater treatment, where they add disinfectants like chlorine to make water safe. In agriculture, they deliver fertilizers or pesticides through irrigation systems with accuracy that prevents waste and environmental harm. While, in food and beverage plants,... --- > An inline static mixer blends fluids in pipelines without moving parts. It improves mixing efficiency, supports chemical dosing, and is used in water, food, pharma, and industrial processes. - Published: 2025-09-17 - Modified: 2025-09-18 - URL: https://wrsdosing.com/chemical-dosing-pump/inline-static-mixer-role-in-chemical-dosing/ - Categories: Chemical Dosing Pump - Tags: Chemical Dosing, Chemical Dosing Pump, chemical dosing systems, Inline Static Mixer An inline static mixer is one of the simplest yet most effective solutions for achieving consistent fluid mixing in pipelines. Unlike traditional mixers that rely on moving parts, an inline static mixer utilizes fixed elements within the pipe to split, rotate, and recombine fluid streams, ultimately forming a uniform mixture. Thus, these mixers play a vital role in improving product quality, system safety, and operational efficiency. What is an Inline Static Mixer? An inline static mixer is a device placed inside a pipeline to mix fluids without any moving parts. Inside, fixed elements like baffles, helical twists, or fins split, rotate, and recombine the fluid streams, blending liquids, gases, or powders into a uniform mixture. A static mixer works without a motor, using the energy from the flowing fluid. Pressure moves the fluids forward, and the mixer’s elements create turbulence and cross-flow for thorough mixing with little energy use. How well it works depends on the design and number of elements inside. Inline static mixers are widely used in industries that require reliable, continuous mixing. In water and wastewater treatment, chemicals such as chlorine or coagulants are added to the water. In food and beverage processing, they blend syrups, flavorings, or gases, such as carbonation. In pharmaceuticals, they help mix ingredients where sterility and consistency are essential. They’re also common in chemical processing and polymer production, where precise blending of reactants is critical. The main advantages are their simplicity, low maintenance (due to the absence of moving parts), and ability... --- > What is the purpose of dosing? Dosing helps avoid giving too little, which does not work, or too much, which can be wasteful or even harmful. - Published: 2025-09-16 - Modified: 2025-09-16 - URL: https://wrsdosing.com/knowledge/what-is-the-purpose-of-dosing/ - Categories: knowledge - Tags: Chemical Dosing, Dosing Pumps, Pharmaceutical Dosing in pumps, chemistry, or medicine means adding the right amount of a substance at the right time. What is the purpose of dosing? Dosing helps avoid giving too little, which does not work, or too much, which can be wasteful or even harmful. In industry, dosing pumps add exact amounts of chemicals like chlorine for water treatment, fertilizer for irrigation, or additives in food and medicine. This keeps processes safe and consistent. In medicine, dosing makes sure patients get enough medicine to help them without causing harm. In agriculture, giving crops the right amount of nutrients helps them grow well and prevents damage to their roots. The main goal of dosing is control. It keeps biological, industrial, and environmental systems working by adding substances in measured amounts instead of all at once. This balance helps make water safe, medicines work well, and factories run smoothly. The Purposes of Dosing Across Industries Dosing is used everywhere, but its purpose changes depending on whether it is for people, water, machines, or soil. Here is how dosing works in different areas: 1. Medical and Pharmaceutical Sector In medicine, dosing is fundamentally about balancing healing and harm.

Instead of flooding a system with fluid, a dosing pump carefully injects precise doses into a stream, tank, or process line at a controlled rate. This precision is crucial in industries where small changes in chemical concentration can lead to problems. What is A Dosing Pump? A dosing pump is a highly specialized pump built not to move large volumes of liquid, but to deliver small amounts with extreme accuracy. It delivers a set amount of liquid into a fluid stream, tank, or process line. However, its main job isn’t to move a lot of fluid. Instead, it ensures small amounts of liquid are added accurately and consistently at a set rate. A dosing pump operates based on a repeated cycle of suction and discharge. During suction, the pump draws liquid from a container or reservoir into its chamber. During discharge, the pump injects that liquid into the target system at a specific flow rate. You can adjust the dosing rate manually or electronically, depending on the design. Many modern dosing pumps now have digital controllers and communication interfaces. This lets them connect with automated systems and allows for precise remote adjustments. Dosing pumps are widely used in industries that require precise chemical treatment or controlled additives. In water and wastewater treatment, they inject chlorine, coagulants, or... --- > This guide explains how stroke adjustment, flow rate, calibration, and turndown ratio work together to ensure dosing pumps deliver accurate, efficient chemical dosing. - Published: 2025-08-11 - Modified: 2025-08-11 - URL: https://wrsdosing.com/knowledge/guide-to-stroke-adjustment-and-flow-rate-in-dosing-pumps/ - Categories: knowledge Many industries rely on dosing pumps for accurate chemical handling. These include water treatment, agriculture, chemical processing, and food production. For any dosing application to succeed, operators need to carefully manage two key variables: stroke adjustment and flow rate. These two factors determine how much fluid the pump doses. They also affect how accurately and efficiently the fluid is delivered. This guide breaks down how stroke adjustment works, what flow rate means in dosing systems, and how calibration and turndown ratio affect precision. What Is Stroke Adjustment? In a dosing pump, the term stroke refers to the full motion of the pump’s diaphragm or piston during each cycle. Stroke adjustment is the ability to change the length or depth of this motion. By increasing or decreasing the stroke length, operators can directly affect how much liquid is dispensed per stroke. Some pumps allow manual stroke adjustment using a dial or handwheel, while more advanced models offer electronic or automatic adjustment via external control signals. This control is especially useful in applications where fluid volume needs to be adjusted in real time. Understanding Flow Rate Flow rate is the volume of liquid a pump delivers over a set period, usually expressed in liters per hour (LPH) or gallons per minute (GPM). It depends on two main factors: Stroke length – How far the diaphragm or piston moves. Stroke frequency – How many strokes the pump completes per minute. Together, these factors determine the pump’s output capacity. Accurate control of flow rate... --- > The Eignal Series EMG model is a smart dosing pump designed to boost industrial efficiency through advanced digital features like RS485 communication, 4–20mA input - Published: 2025-07-30 - Modified: 2025-07-30 - URL: https://wrsdosing.com/knowledge/what-makes-a-smart-dosing-pump-a-deep-dive-into-the-eignal-series-emg-model/ - Categories: knowledge In industrial operations where accuracy and reliability are non-negotiable, smart dosing pumps are practically the best for keeping operations smooth and cost-effective.   But what exactly makes a dosing pump smart?

Unless you are an engineering student, DIY pumps aren't going to suffice. Definition of Peristaltic is that its a wavelike muscular contractions in tubular structures. In terms of the word 'Peristaltic' within industrial settings, peristaltic pumps (also known as roller pumps) are a kind of metering pump that operates primarily on compress and relax mechanism (as shown in the figure above) that works well for processes such as drinking water plants, pharmaceutical settings or when there is no room for the risk of contamination. The compression system works in one way direction to prevent the fluid from going back up the hose decreasing the chance of contamination and backflow. A roller presses the hose down flat so that the discharge valve as well as the suction cap are both sealed and chemical input can neither leave nor enter the hose after each convulsion. Then, in an alternating movement the hose again fills up with the exact dose of the chemical and that is propelled forward into the effluent. The chemical medium that needs to be pumped out is never put into contact with any other part of the whole pump, but, is stored in the hose for maximum protection. An extended tube is also attached to the tube to store the chemical medium.

Fluid Temperature Never decide on a particular style of dosing pumps such as a peristaltic pump or a Diaphragm type pulse injection without knowing the average temperature requirements of the fluid you will be dosing. Since the fluid will be pumped frequently and repeatedly, this seemingly small aspect may, in fact, become a gigantic problem especially if compatible parts are not used. Knowing the Pressure Temperature is not the only factor that affects the inlet and the outlet of the dosing pump. The correct equipment can only be chosen if the level of pressure has been accurately measured beforehand. That means, liquid dosing is actually based upon choosing the right pumps that can handle the needed pressure range. In the Event of a Leak Over time it is not unusual for leaks to occur in industrial equipment such as large dosing pump settings. In many cases, this happens because the dosing fluid has corrosive properties or the wrong type of dosing pipe was used.

However, since there are many metering pump suppliers on the market creating low-quality metering pumps, as a result due to several extraneous factors such as temperature and pressure; input and output results, as well as measuring the accuracy can be affected greatly. How Outcome Can Be Affected In theory, a metering pumps are engineered towards great deal of precision largely due to a pump head displacement, but the factors that can create anywhere from a 10% to a 30% variation in the results are as follows: The temperature of the surroundings in which the pump is operating as well as the temperature of the fluid being pumped. Air can get trapped in a pump very easily especially with excessive use or heat which can greatly affect chemical dispersion. The daily wear and tear of all components related to the metering system and the dosing pump itself. Shifts in the pressure level can also cause discrepancies in output. Flow Meter Can Ensure Accuracy A flow meter measures ‘direct mass flow’ and regulates it with what is known as a ‘principle of operation’ or PID device. A predetermined limit is set on the flow meter which then implements these directions on the metering pump. The process is simple and increases efficiency especially if you are using the pump in an area with significant interfering factors such as heat and or weather.

Either way, imagine trying to write using your opposite hand, the words won't be written as good as your normal writing. Same is true when it comes to choosing the right dosing pump. The outcome upon setting up your dosing system must be exactly what you require for dosing fluids or chemicals or even water. As you may know that dosing pump has the primary function of moving an exact and specific amount of fluids (into water, chemicals, gas or steam). This process is known as 'metering' as a result dosing pumps are also called metering pumps. There are many factors that go into choosing the right dosing pump for your requirements while also staying within budget. Ideally, the pump should be chosen according to the pressure it can exert, the temperatures it can stand, and should be compatible with the fluids that need to be dosed. In some cases, these factors are neglected or ignored and this can result in serious accidents because most often times dosing pumps are used with chemicals. It is worthwhile to note that if you are dosing fluids of a considerable temperature, you will need to be wary of the dosing pipes that you are using. Strong metal or PVF2 performs generally better in these conditions when compared with plastic. PVDF: (PVF2 or Polyvinylidene fluoride) is a semi-crystalline high purity thermoplastic fluoropolymer with service temperatures up to 150°C and has these properties Chemical resistant High mechanical strength... --- > Different Types of Dosing Pumps.

The most common uses of chemical dosing pumps and dosing equipment are listed below. The most widespread use of chemical dosing pumps can be understood as the treatment of fluids for any type of purpose, particularly water and chemicals. Water treatment applies not just to wastewater, industrial effluent or sewage but also to regular river water that needs to be purified and made drinkable for human consumption. In many cases, large bodies of water which have uncertain levels of impurities and contamination are treated in water treatment plants even if the water is not ‘dirty per se’. Amines to Stop Corrosion Amines and related corrosion inhibitors are important chemicals that are routinely dosed in industrial plants. This is done largely to prevent the build-up of rust or other substances that can be harmful to machinery and plant infrastructure. Equipment such as boilers and steam turbines can be vulnerable to damage and build-up so these chemicals really help in maintenance and longevity. Sodium Hypochlorite And Other Disinfectants Disinfection and decontamination is a common application of dosing pumps, and this is done largely by using chemical compound called Sodium hypochlorite. Part of the composition of this chemical is Chlorine Cl2 which is used largely for disinfecting the water in swimming pools. Sodium hypochlorite is very effective in killing germs since it eradicates the cell... --- > Chemical Dosing Pump Maintenance. Wear & Tear.

With so many moving parts, its not an option but a necessity to make sure we don't end up on the side of the road stranded. At the end of the day, we want to make sure that we get the most mileage from our cars before things go wrong. Same as true when using chemical metering pumps or dosing pumps which require timely and regular maintenance just like any other piece of industrial equipment. Because productivity matters. There are many issues that commonly arise from metering pumps when they are used day in and day out and this applies especially to the equipment that is connected to them such as dosing pipes and safety valves. Wear & Tear At the core of it all, chemical dosing pumps are engineered to move fluids, be it at high temperature, high pressure or corrosive chemicals which requires the core materials to be fit for the purpose accordingly. As a result, the area that surrounds a chemical metering pump stays in contact with fluids and water constantly and also it can become excessively wet over time causing issues such as rust and rot can sink in. Although newer pump designs are optimized for high flow rates with less chance of leakage of fluids, maintenance can avoid seepage into the area surrounding the metering system. Regardless of the type of metering pump you have set up, you will need to reassess the area... --- > Dynamics of a Chemical Dosing Pump.

Control of the flow rate is also an important part of the dosing process itself, and this is determined by many factors such as the nature of the liquids, chemicals and water being treated and the purpose of treatment. The primary function of a dosing pump is that of a chemical delivery system and this is done with a high level of accuracy. A predetermined amount is first drawn into a chamber, and then through pipes leading to the tank or water storage unit, transferred back into required form of the liquid. Even though it carries out an enormous task, dosing pumps in themselves are rather small devices which can be operated either with (Electric, Air Operated Diaphragm Pump, Motor or Solenoid Driven chemical dosing pumps or basic actuator). Most dosing pumps are controlled by an external control system but some have regulation switches inside them which can specify the flow rate. The newer models of dosing pumps that are available have a range of options that make the device very easy to operate. There are monitoring systems available inside modern dosing pump models such as ones to indicate low product levels, alarms, time-specific on/off buttons, and timely warnings. The Mechanics of a Dosing Pump The dosing pump is made up of several parts,... --- > Beginner's Guide to Using and Setting Up Dosing Pumps.

These can by anyone from Water Treatment, Electroplating, Mining to Pulp and Paper industries. Even the medical Pharmaceutical industry uses dosing pumps for a variety of functions. The main purpose of using a dosing pump is to cause a flow and chemical reaction in a body of fluids even if it is a simple one such as adjusting the PH level or the chlorine level as is commonly done for swimming pool water. While in many cases an acid is injected into the water for a particular chemical reaction, flocculants are also used to make solids settle down to the bottom. Flocculating agents can also change the composition of the water and make it safe to use. Dosing is however not only for changing the properties of water, but it does also help in manufacturing various products. Dosing pumps are helpful in metering of fluids, corrosion inhibitors, biocides, high pressure and high-temperature fluids such as boiler feed can also be treated with dosing pumps, although changes in components used manufacturing dosing pumps are often required such as using polypropylene, aluminum, stainless steel instead of just poor quality plastic dosing pipes. First Consider These Before Setting Up Dosing Pumps Whenever chemicals or high pressure / temperature substances are handled, we must first take precautions for safety because you may be working with highly dangerous chemicals for dosing process. If wrongfully handled, operator error, pumping inaccuracies, chance of leakage and... --- > The Easy Guide to Choosing a Metering Pump.
