Plunger Metering Pumps

Plungers are synonymous with accurate metering

The heart of the liquid end in a plunger metering pump is a high-resistance plunger made from coated stainless steel. As soon as the plunger is moved into the dosing head, the suction valve closes and the feed chemical flows out of the dosing head through a discharge valve. When the plunger moves in the opposite direction, the discharge valve closes due to the negative pressure in the dosing head. Fresh feed chemical flows through the suction valve into the dosing head.

The versatile solution for all industries

ProMinent plunger metering pumps can be found in oil and gas production (onshore/offshore), refineries, the chemical / petrochemical industry, the pharmaceutical, cosmetics and food production industries, and as bottling pumps in the packaging industry.
