Diaphragm Metering Pumps

Not just sealed, hermetically sealed!

The hermetically sealed metering units and resistant materials of ProMinent diaphragm process metering pumps enable them to pump aggressive media with ease. But that’s not all because 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

Strong diaphragms, sealed metering units and resistant materials make just the right combination in oil/gas production (onshore/offshore), refineries, and the chemical / petrochemical, pharmaceutical, cosmetics and food production industries. We recommend special ProMinent metering pumps for the process industry.

Practical benefits

The micrometre adjustment dial for the stroke length guarantees precise adjustments and high reproducibility. Compensation means that the pump is operated reliably even during fluctuations in mains voltage. Different control types make easy process integration possible. The dosing head is self-bleeding, which also makes it suitable for outgassing media.

Keep moving

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