Hydraulic Diaphragm Metering Pumps

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. MBN hydraulic diaphragm metering pumps therefore use a hydraulic fluid to create back pressure. You will soon notice the benefits for the diaphragm.

Where MBN 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.
