Optimum Solids Handling and Low Shear Pumping

Rotary lobe pumps use timing gears to eliminate contact between the rotors, which allows their use on non-lubricating liquid.  Various rotor forms are available, including bi-wing and multi-lobe options.  These pumps offer low shear and gentle handling of the liquid to minimize product degradation.

Features & Benefits

  • Higher Pressure Capabilities

    For long distance transfer of high viscosity liquids.

  • Easy Timing

    Rotors and gears are positively located on key shafts.

  • Simple End Clearance Adjustment

    Compared to other lobe pumps which require shimming.

  • Shaft Seal Options

    Including packed gland, component seal and cartridge seal options.

  • Excellent NPSHr

    Fluid access on three sides of rotors enhances filling with highly viscous fluids and minimizes pulsation.

  • Run Dry Continuously

    Non-contacting rotors enable continuous run-dry with flushed seal, minimizing chance of failure due to operator error.
