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.
