ProMinent Hydraulic Diaphragm Metering Pumps

ProMinent’s hydraulic diaphragm metering pump range boasts precise dosing and minimal maintenance. All pumps in this group are equipped with a pressure relief valve to protect against overload. They also have a multi-layer diaphragm with a rupture warning system to ensure operator safety, mitigate critical downtime, and prevent the feed chemicals from mixing with the hydraulic oil.

Another selling point of ProMinent hydraulic diaphragm metering pumps includes the sealless, no-leak design, which makes them suitable for handling hazardous chemicals and other challenging fluids.

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 hydraulic diaphragm pump—to ensure that accurate volumes are dosed regardless of the pressure of the line they are injecting into. Hydraulic diaphragm pumps transmit power using operating oil filled between a diaphragm and a piston that serves as the drive source.

Metering pumps can be controlled in various ways, from rotation speed to stroke length within a solenoid metering design or via relay or timer—for this series, a solenoid.
