Borger Rotary Lobe Pumps Grinders

Borger Rotary Lobe Pumps are positive displacement pump conveying the conveyance of low to high, viscous and abrasive materials. to and from thickeners, belt presses, centrifuges, rotary presses, digesters , air entrained fluids, DAF, and industrial slurries. They handle thick solids greater than 2% up to 2000 gpm and pressures up t0 150 PSI. Rotary lobe pumps can run dry and are capable of self-priming. The rotation of the pair of lobes increases suction chamber pressure and creates a vacuum on the priming side of the pump drawing liquid into the pump chamber.

  • Suitable for Run Dry conditions.
  • Small Footprint
  • Pumps froth, DAF or air entrained fluids/sludges
  • Self Priming
  • Wearing parts replaced (seals, lobes and wear plates) without removing attached piping.
  • Front wear plates reversible for extended use.

BLUEline Pump Series
BLUEline series of pump is ideal for transferring sludge to and from thickeners, belt presses, centrifuges, rotary presses and digesters.


  • Wastewater: Transfer to/from Thickeners, Belt Filter Presses, Screw Presses, Centrifuges, Digesters, RAS/WAS
  • Biodiesel slime
  • Pesticides – handles crystals and high temperatures
  • Sodium Sulphate:
    • Amine recycling plant where amine sulfate delivered is processed in a rectification system. Caustic soda reacts with the sulfuric acid contained in the amine sulfate forming sodium sulfate.
  • Slaughterhouse: Animal Blood – handles with ear tags
  • Bentonite – horizontal flushing bore rigs
  • Natural Latex
  • Adhesives – tile and parquet
  • Hydrogen peroxide, Tristyrylphenol, Fatty acid methyl ester, Melt
  • Cosmetics, Soap, Detergents, Vegetable/animal fats, Glycerine residues, Viscose fiber, Soapstock

Maintain in Place

  • The pump is designed so wear components can be replaced through the quick-release cover of the pump.

  • All maintenance work can be done without removing the pump from the suction or discharge piping or the drive system.

  • See video for ease of disassembly to remove lobes, wear plates, mechanical seals, etc

Optimized Rotor to Maximize Efficiency –
Replaceable Lobe Tips

  • Rotors available in variety of configurations and materials.

  • Popular among operators/maintenance staff are lobes with replaceable rubber tips. If pump wears, replace the tips versus entire lobe.

  • Lobes can be retrofitted to optimize performance in existing pumps.

  • See video above on ease of replace lobe tips in-situ:

Mechanical Seal Replacement

Borger has replaceable stationary and rotating seal faces that can be economically replaced without replacing the entire seal components. Watch the video to see the ease of seal replacement.
