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. You will soon notice the benefits for the diaphragm.

Where ProMinent hydraulic technology is found:

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

Your benefits

It works, it works well, and it lasts for a long time. The hydraulic control is very precise and requires only minimal maintenance. The diaphragms are durable and provide consistently accurate metering. The technology also offers a 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 there is no risk of the feed chemicals mixing with the hydraulic oil.
