Types of SS Rotary Lobe Pumps

  • Bi Stainless Steel Lobe Pump
  • Tri Stainless Steel Lobe Pump

Working Principle of SS Lobe Pump

SS Lobe Pump consists of two synchronized rotors present in Lobe pump, this lobe rotate in opposite directions inside a casing. The rotors have lobes that interlock and create a series of cavities, when the cavities move the liquid moves from the inlet side to the outlet of the lobe pump. The cavities have a decreasing volume, it creates a vacuum that sucks the liquid into the pump.

“ DEV ” DELB Series Stainless Steel Rotary Lobe Pumps are positive displacement pump technology used widely across the pharmaceutical, food and beverage industries. The pumps action means they are capable of handling shear sensitive materials with low shear.

The rotors are provided with so-called lobes, which rotate past each other without touching each other. The shape of the lobes can vary and the number of lobes can also differ. Due to this design, the lobes of the two rotors intertwine, thereby pumping the liquid in axial direction.

Lobe contact is prevented by external timing gears located in the gearbox. Pump shaft support bearings are located in the gearbox, and since the bearings are out of the pumped liquid. As the lobes come out of mesh, they create expanding volume on the inlet side of the pump.

Liquid flows into the cavity and is trapped by the lobes as they rotate. Liquid travels around the interior of the casing in the pockets between the lobes and the casing and it does not pass between the lobes. Finally, the meshing of the lobes forces liquid through the outlet port under pressure.

SS Rotary Lobe Pump Features

  • Can either be horizontal or vertical foot mounted as per requirement.
  • Can be provided with geared motor or with built – in speed reducer.
  • The sealing options provided in this series are either mechanical seal or lip seal, as per the application and requirement.
  • The standard direction of rotation is anti-clockwise from the pump shaft end with left IN and right OUT configuration.
  • The number of lobes per rotor varies from 2 to 6.
  • More the number of lobes, higher the chances of less pulsating discharge.
  • Max. Capacity up to 100 m3/hr.
  • Handle Viscosity up to 200000 cps.
  • Standard Max. Temperature to 110 Deg C.
  • Jacketing Feature available if liquid has Crystallisation nature.
  • All Wetted Parts AISI 316.
  • Hard Face Hygienic Mechanical Seals.
  • Suction & Discharge Ports available in Tri-clover / Dairy SMS / BSP Screw End / Flange End as per request.
