Hydraulic Diaphragm Metering Pumps

Pressure and back pressure

High pressures are no problem in metering systems as long as there is something to counter them. ProMinent hydraulic diaphragm metering pumps therefore use a hydraulic fluid to create back pressure. The benefits this brings to the diaphragms become evident very quickly.

The industries in which ProMinent’s hydraulics technology is used:

  • Oil/gas production (onshore/offshore)
  • Refineries
  • Chemical / petrochemical industry
  • Pharmaceuticals & cosmetics
  • Food production
  • Packaging industry (bottling pumps)

What you can expect

The pumps run. They do this well and for a long time. Your hydraulic control is very precise and requires only minimal maintenance. The diaphragms are durable and provide consistently accurate metering. The technology also offers a very high standard of safety: there is a pressure relief valve in the hydraulic end as protection against overload. The multi-layer diaphragms are equipped with a diaphragm rupture warning system as standard. So you can be sure that the feed chemicals cannot mix with the hydraulic oil.
