Design and function

The liquid is conveyed by a deformable drive diaphragm. This membrane is connected via a connecting rod fixed to the drive magnet and so is deflected to the suction and pressure strokes.

Solenoid diaphragm pumps consists of the follwowing (main) components:

  • Drive housing with solenoid
  • Elektronics with connection on the control panel
  • Built-in pump
  • Pump body
  • Manual vent valve
  • Suction valve and pressure valve

Materials and options

A suitable material is available for each dosing medium!

  • Pump body and Valves: PP-FRP, PVDF-FRP, PVC, PP, PVDF, 1.4571
  • Valve balls: PTFE, 1.4401, Al2O3
  • Valve seals: EPDM, FPM, FEP-covered, FFKM1)
  • Working diaphragm: PTFE-faced
