Introduction to a motor driven dosing pump
This is the most common driving method by all chemical dosing pumps. WRS motor driven dosing pumps are designed to be operated with the minimum input power yet able to produce high flowrate and high pressure performance. Helping our client to get the most value out of a chemical dosing pump. Motor-driven dosing pumps are more robust, reliable and able to run on their own without supervision. Dosing pumps with mechanically actuated diaphragms can be used almost universally in low pressure ranges.
Adjustable flowrate
The stroke length and stroke rate – in this case the motor speed – can be adjusted to alter the capacity of this pump. The rotation of the electric motor is stepped down by a worm gear and converted into a linear stroke movement by a cam. The slide rod transfers this stroke movement to the diaphragm in the dosing head. Two non-return valves prevent the feed chemical from flowing back during pumping.
The motor-driven metering pumps can handle the following substances:
- Chemicals up to over 1,800 l/h
- Disinfectants in potable water treatment
- Disinfectants in cooling circuits
- Flocculants in waste water treatment
- Additives in the paper industry
- Additives in plastic manufacturing
Impressive benefits
The pumps offer a very wide performance range. They also offer extremely accurate metering even under fluctuating pressure conditions (rigid characteristic curve). This results in reduced chemical consumption and precise process control.
Need a higher performance class? These pumps always deliver robust, low-cost power. They are also flexible: they can be controlled via the stroke length and motor speed, allowing them to be seamlessly integrated and/or retrofitted in automated processes. Energy consumption depends on the power required, not the other way round. And lastly, specially designed metering profiles allow optimum metering results.
Stay in control
The multi-layer safety diaphragm with diaphragm rupture indicator offers maximum safety. There is also an overload shutdown to protect the pump.
