Piston diaphragm pumps for extremely demanding industrial applications

Electric piston diaphragm pumps are used in very harsh industrial applications where high pressures, abrasive media and high viscosity place extreme demands on the equipment. These pumps are particularly suitable for processes with a high proportion of solid particles and where operational reliability is crucial.

Piston diaphragm pumps combine the power of the piston pump with the tightness of the diaphragm, providing safe and controlled pumping even under very demanding operating conditions.

Piston diaphragm pumps for filter presses

One of the most common applications for piston diaphragm pumps is feeding of filter presses, where the pump works in two distinct stages:

  • Initially, the filter press is filled with large volumes at low pressure
  • Then filtration takes place with smaller flows and very high pressure

The piston diaphragm pump automatically adapts to the varying operating conditions of the process, providing an efficient, safe and energy-efficient filtration process.

Technologically advanced electric piston diaphragm pumps

For applications requiring the transport of liquids over long distances at high pressures and temperatures electric piston diaphragm pumps are often the most technically and economically favourable choice.

The electric drive provides:

  • precise control of flow and pressure
  • high operational reliability
  • flexible integration in industrial processes

At the same time, the membrane design ensures gentle handling of shear-sensitive media.

Applications for piston diaphragm pumps

Piston diaphragm pumps are used to advantage in applications where other pump types are not sufficient, for example when pumping:

  • abrasive and abrasive media
  • aggressive chemicals
  • highly viscous liquids
  • media with high concentration of solids

Our piston diaphragm pumps from Emmerich supplied in standard versions for pressure classes up to 160 or 250 bar, with the possibility of even higher pressure if needed.
