Hydraulic Diaphragm Metering Pump

Capacity range 3 – 23 l/h, 400 – 25 bar

The Evolution mikro is an innovative micro-metering pump for high pressures. The hydraulic diaphragm metering pump is the first of its kind with an electronically regulated direct linear drive. The power end does not contain any mechanical functional elements and thus works virtually maintenance-free.

Product description

For the smallest quantities at the highest pressures

With a capacity range of 0.01 – 23 l/h at pressure of up to 400 bar, the hydraulic diaphragm metering pump Evolution mikro EFMa and EHMa is extremely suitable for applications in gas metering and for ultra-precise micro-metering in filling processes of all kinds. It is also used for additive metering in the petrochemical and chemical industry. The Evolution mikro is designed in compliance with API 675, ATEX and FDA.

Your benefits

Maximum process reliability:

  • Precise micro-metering at high pressures
  • Hermetically sealed by PTFE or metal multi-layer safety diaphragm
  • Long service life thanks to its sturdy construction with non-wearing, contactless power end
  • High positioning accuracy (in the micron range) and zero backlash (no overload)

Excellent flexibility:

  • Seriously extended adjustment range of 1:200
  • Universally controllable with electronically integrated overload protection

Field of application

  • Gas metering
  • Additive metering in the petrochemical and chemical industry
  • General filling processes in industry
  • Food industry
