Solenoid Diaphragm Metering Pumps
Solenoid diaphragm metering pumps from ProMinent deliver reliable metering even under the harshest operating conditions. Solenoid diaphragm metering pumps with an output range of 0.74 to 75 l/h at a back pressure of 16 - 2 bar can be used in virtually all applications.
Thanks to the broad range of materials offered, these metering pumps are suitable for practically all liquid chemicals.
Operation/features
A solenoid moves the solenoid axis back and forwards by switching on and off. This stroke movement is transferred to the metering diaphragm in the dosing head. Two return valves prevent the feed chemical from flowing back during the pumping process. The metering capacity of a diaphragm metering pump can be adjusted using the stroke length and the stroke frequency.
Applications
- General: chemical metering up to 75 l/h
- Treatment of drinking water: metering disinfectants
- Cooling circuits: metering disinfectants
- Treatment of waste water: metering flocculants
- Paper industry: metering additives
- Plastic production: metering additives
Advantages
- Virtually wear-free drive, as only one moving part is used. Pump works without lubricated bearings or shafts. Maintenance and repair costs are therefore extremely low.
- Excellent continuous run characteristics
