Solenoid-Driven Metering Pumps

What They Do

Solenoid-driven metering pumps are available in capacities ranging from 0.74 to 80 l/h at a back pressure of 25 to 2 bar. To be able to meter almost any liquid chemicals, ProMinent uses a very extensive range of materials.

How They Work

A solenoid 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 check valves prevent the feed chemical from flowing back during pumping. But that’s not all. The stroke length and stroke rate can be precisely adjusted to alter the metering rate of ProMinent solenoid-driven metering pumps.

Where They Are Used

• General: Metering of chemicals of between 1 ml/h and 80 l/h
• Drinking Water Treatment: Metering of disinfectants
• Cooling Circuits: Metering of corrosion inhibitors and biocides
• Waste Water Treatment: Metering of flocculants
• Paper Industry: Metering of additives
• Plastics Production: Metering of additives

What Are the Advantages?

Because there is only one moving part, the drive is virtually wear-free. The pump requires no lubricated bearings or shafts; the maintenance and repair costs are therefore very low. The continuous running characteristics are excellent.
