Membrane Pumps

Description & Characteristics

The membrane pumps belong to the group of positive displacement pumps. They are powered by an air motor. Two membranes, which are connected by a pump shaft, are moved back and forth by the compressed air which is by turns introduced into the air chambers behind the membranes.
The process of air displacement is carried out automatically by means of control valve when membrane reaches its end position.
The pumps can handle clean liquids with low viscosity as well as viscous abrasive liquids with large solids.


Membrane pumps of APM series

Because of the absence of electric drive, membrane pumps can be used in explosion-hazardous areas.


Advantages of the diaphragm pumps:

  • self-priming, without preliminary filling;
  • "dry running" is possible without damages;
  • completely air-proof
  • electric drives are not used;
  • easy to disassemble and clean;
  • minimum amount of spares.

Technical characteristics:

Capacity - up to 500 l/min

Suction height - up to 8 m

Head - up to 70 m


Materials:

polypropylene, PVDF, stainless steel, aluminum.
