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.
