ProMinent Diaphragm Metering Pumps

They use durable, high-quality diaphragms to ensure maintenance and fault-free operation. These dosing pumps are hermetically sealed, making them the first choice in dosing aggressive media. Being leak-free also makes them ideal for sanitary applications in the food, chemical, cosmetics, and pharmaceutical industries.

PRINCIPLE OF OPERATION

Dosing or metering Pumps consistently and accurately deliver sets of volume into a process. They are usually positive displacement types - in the case of this series, a diaphragm pump - to ensure that accurate volumes are dosed regardless of the pressure of the line they are injecting into. Metering pumps can be controlled in various ways, from the speed of rotation to stroke length within a solenoid metering design or via relay or timer – for this series, a solenoid.
