Defoaming pumps PSVP

The stainless steel PSVP defoaming pumps are capable of pumping foaming slurries during the starch production process. 

A special internal contruction enables transporting slurries containing air or foam. First the liquid is de-aired and defoamed in the so-called defoaming compartment. Subsequently, the liquid enters the pump casing via guide-blades where it is pumped away.

If the liquid contains fibres as well as foam, a spiral screw can be fitted onto the product impeller

Depending on the application and the requirements the PSVP can be equipped with various options:

  • Spiral screw
  • Single or double oil seal with grease lubrication
  • Vacuüm nozzle
  • Pressure gauge for vacuum pressure monitoring
  • Drain connection
