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)
Chemical and petrochemical industry
Pharmaceuticals & cosmetics
Packaging industry (bottling pumps)
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.
