Cleghorn - About Jabsco Lobe Pumps

Rotary Lobe Pumps
hyline pump

  • Hygienic - approved to American 3A standard
  • Gentle pumping action suits viscous, delicate and particle-laden liquids
  • Easy to clean, easy to maintain
  • AISI316 stainless steel construction

JABSCO Hy~Line rotary lobe pumps are robust, durable machines designed for long life in demanding applications. Modular construction, using interchangeable parts, enables pumps with a wide range of seal, port and rotor configurations to be built and motorised on short lead times.

24 Series
Rotary Lobe Pumps

Jabsco 24-series hygienic rotary lobe pumps have been in service worldwide for nearly 20 years. The continued popularity of the 24-series reflects the advanced hygienic design and manufacturing methods brought in by Jabsco at the time of its introduction. 24-series pumps use the tri-lobe rotor design proven in service with the world's leading producers of food products, pharmaceuticals and cosmetics

Flow rates up to 126m³/hr (35 litres/second)
Pressures up to Up to 10bar (146 psi)
Temperature range: -40ºC to +200ºC
Liquid viscosity range: 1 to 1,000,000 centipoise

  • Adaptable: modular design permits prompt pump assembly to suit the exact specification required for a given application.
  • Rugged: large diameter shafts, mounted in precision tapered-roller bearings and rigidly mounted for maximum shaft stiffness, to resist over-pressure and other kinds of rough use.
  • Low Maintenance: shaft, bearing and gear assemblies are immersed in an oil bath, for long life even at the pump's limits of operating pressure and temperature. Fully interchangeable rotors avoid the need for routine re-timing, but the timing gears are easily accessible if re-timing should become necessary.

  • Fully self-draining pump head: no hold-up of process liquid or cleaning agents.
  • Rapid de-contamination and product change-over.
  • External rotor fixing - no internal crevices.
  • Low-carbon 316L stainless-steel for maximum corrosion resistance.
  • Controlled-compression gasket-type joints and no O-rings in product contact.
  • Shaft seal designcombines highest levels of containment with total product draining, no cavities, and front access for easy inspection and fast maintenance.
  • Standard surface finish: 0.8µm (150 grit), with 0.5µ (240 grit) and electropolish options.
  • Optional steam/sterile fluid barriers on joints, for true aseptic processes.
  • High efficiency to minimise damage to shear-sensitive low viscosity fluids.
