Diaphragm Metering Pumps

Not just sealed, hermetically sealed!

Hermetically sealed metering units and resistant materials allow ProMinent diaphragm process metering pumps to convey aggressive media with ease. But that's not all. Maintenance-free and fault-free operation also depends on the quality of the diaphragm, which is why ProMinent always ensures that its products are equipped with extremely durable diaphragms.

Tried-and-tested combination

A strong diaphragm, sealed metering units and resistant materials make a very useful combination in oil/gas production (onshore/offshore), refineries, and the chemical and petrochemical, pharmaceutical, cosmetic and food production industries. In the process industry, ProMinent special metering pumps are used.

Practical benefits

The micrometre adjustment dial for the stroke length allows the operator to make precise adjustments and achieve high reproducibility. Operation remains reliable even during fluctuations in mains voltage thanks to compensation. Different control types make easy process integration possible. The dosing head is self-bleeding, which also makes it suitable for gaseous media.

Keep moving

ProMinent always holds a wide range of pump accessories in stock. Our principle is that ProMinent pumps are extendable, flexibly adaptable and modular in design. The pump should fit your requirements, not the other way round.

Pump Guide

The choice of pumps is huge: 80 industries, 100,000 products and infinite applications. To make it as easy as possible to find your ideal metering pump, ProMinent designed the Pump Guide. All it takes is a few clicks to find a selection of suitable models.

How it works

First enter the pump capacity and back pressure. The Pump Guide will then show you all the metering pumps that match your criteria. You can choose between list view and detail view. The database contains all solenoid-driven metering pumps, motor-driven metering pumps, process metering pumps and peristaltic pumps from ProMinent. They are divided into more than 30 different product ranges.

Exactly the right pump

Narrow down your search by clicking on different selection criteria. Do you have a specific industry, operating mode, medium or viscosity in mind? Or maybe you need a pump for zones at risk of explosion? The Pump Guide will take you to the pump you need with just a few clicks.
