For the smallest quantities at the highest pressures
With a capacity range of 0.02 – 18 l/h at pressures of up to 400 bar, the hydraulic diaphragm metering pumps Evolution mikro EMFa and EMHa are extremely suitable for ultra-precise micro-metering in gas metering and filling processes of all kinds. They are also used for additive metering in oil, gas and chemical applications, etc.
Typical applications include the metering of additives in gas metering and filling processes.
The Evolution mikro is the first of its kind with an electronically regulated direct power end. It can be ideally adapted to the respective application, thanks to an adjustment range of 1:200 and the combination of individually independent metering profiles Metering profiles guarantee optimum metering results by adapting the metering behaviour of the ... more in the glossary with 3-parameter control.
