Solenoid-Driven Metering Pumps

Solenoid-Driven Metering Pumps

What they do
Solenoid-driven diaphragm metering pumps are available in capacities ranging from 0.74 to 75 l/h at a back pressure of 25 to 2 bar. To be able to meter almost any liquid chemicals, MBN uses a very extensive range of materials.

How they work
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 is not all. The stroke length and stroke rate can be adjusted to alter the capacity of a MBN solenoid-driven metering pump.

Where they are used
General: Chemical metering up to 75 l/h
Potable 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.
