Kel-Cell diaphragm technology

With Kel-Cell diaphragm technology developed by Wanner Engineering, the risk of diaphragm rupture can virtually be ruled out. The innovative diaphragm position helps the diaphragms of Hydra-Cell pumps to balance unfavorable conditions on the suction side.

Unfavorable system conditions include: 

  • Inadequate fluid supply due to blockage
  • Clogged inlet filter or closed inlet shut-off valve
  • High viscosity liquids or insufficient differential pressure
  • All conditions that lead to a vacuum on the suction side.

An unplanned system failure, a bad system design or even a faulty installation can lead to a vacuum on the suction side. This can bring the diaphragm out of hydraulic equilibrium and deform or destroy the diaphragms.
