ROTARY LOBE PUMPS

For high viscosity applications and filled materials

Heavy duty long life pumps.
The piston system consists of single-bladed or double-bladed circular pistons that rotate against the moving piston surface of the mating piston.

The piston system ensures:

  • foam-free conveyance
  • a medium suction capacity (suction height up to 4m)
  • piston speeds up to 150 rpm (KS), 750 rpm (KKPS)

To promote:

  • highly viscous, non-flowing media
  • highly filled materials to be conveyed with a dry substance content of up to 94
  • coarsely contaminated materials to be conveyed
