Rotary Lobe Pumps

Engineered for high-performance fluid transfer in stringent, hygiene-conscious industries — a compact, low-maintenance pump built around a fully swept pumping chamber.

What it does.

Heavy-duty, large-sectioned stainless shafts minimise deflection under load. Helical gears time the main and lay shafts precisely, maintaining exact rotor clearances for high volumetric efficiency.

All wetted components are 316 stainless. O-ring seals are profiled to the edge of the pumping chamber and flush covers eliminate dead spots where bacteria could establish.

Liquid media it handles.

  • Food, beverage or dairy
  • Viscous or shear-sensitive

Where it is specified.

  • Food & beverage
  • Pharmaceutical

Engineering features.

Fully swept chamber

No dead spots. Cleans in place and passes hygiene audit.

12-involute spline rotors

Accurate rotor positioning on assembly and reassembly.

Spigotted rotor case

Positively located on the bearing housing — no loose dowels.

Pressure relief option

Front covers can carry an integrated relief valve.

Full-diameter porting

Unimpeded flow as standard; custom fittings available.

If this is not the right geometry.

Three other ranges that may suit the duty better.
