Jabsco Hygienic Rotary Lobe Pumps

Jabsco logo

Jabsco's latest rotary positive displacement pump incorporates the very latest in hygienic design concepts in order to fulfil the ever-increasing customer demands for improved cleanability, hygiene and sterilisation.

This design uses a bi-wing rotor, which encompasses the very best features of tri-lobe pumps and circumferential piston pumps. The pump is built upon Jabsco's 40 years' experience of producing and supplying their Flexible Impeller and 24 Series rotary lobe pump to the world's most demanding markets.

Design Features and Benefits:

  • Front mounted shaft seals for easy replacement and full accessibility of CIP liquids
  • Fully interchangeable bi-wing rotors can be fitted without the need to re-time, thus reducing downtime and allows pump to cope with a higher level of abuse
  • Rotor shimming occurs within the pump head, therefore there is no need to fully dismantle it
  • Flush fitting, sealed rotor retaining screws avoid build up of stagnant product as no end cover recesses are required and no product can get into the rotor drive
  • Rugged, high grade alloy bearing pedestal and housing for low weight and high strength, completely encased in epoxy coating
  • High specification taper roller bearings give over one million hour's life on a typical duty
  • Precision cut spur gears for high load capability and ease of maintenance
  • Heavy duty shafts for high pressure capabilities
  • Flow rates up to 1800 litres per minute and 15 bar maximum pressure

How do they work?

1. Fluid is drawn into the pump and completely fills the space between the rotors.
2. Held between the rotor lobes and the pump case, closed cells of fluid are carried smoothly through the pump.
3. The intermeshing rotor lobes positively displace the fluid volume, generating flow and overcoming the discharge pressure.
