Ring piston pumps

Strong in use, gentle on the medium

Rotary lobe pumps are reliable positive displacement pumps that are characterized by their versatility in industrial applications.

They pump low-viscosity to medium-viscosity media with low pulsation. The special design guarantees low shear and good suction capacity of the pumped medium.

Specifications

  • Delivery rate 2 to 96,000 l/h
  • Differential pressure up to 15 bar
  • Viscosity range approx. 0.3 to approx. 10,000 mPas
  • Self-priming
  • Temperature range -10 to 250 °C

Precision in motion: reversible and powerful

Ring piston pumps use the principle of an eccentrically rotating piston in a cylinder. The rotation of the eccentric shaft creates opening and closing chambers between the piston and cylinder.

When the chambers are opened, liquid is drawn in through slots at the front, and when they are closed, the liquid is pressed through them into the pressure line. This process enables efficient fluid transportation and can be reversed by changing the direction of rotation.
