Rotary Lobe Pumps Details

Rotary lobe pump use timing gears to eliminate contact between the rotors, which allows their use on non-lubricating fluids. These pumps offer low shear and gentle handling of the liquid to minimize product degradation. Rotary lobe pumps are useful for pumping and Transfer of all high viscous liquids like syrup paints, drugs, food products, etc.

Lobe pump is used in a variety of industries including, pulp and paper, chemical, food, beverage, pharmaceutical, and biotechnology. They are popular in these diverse industries because they offer superb sanitary qualities, high efficiency, reliability, corrosion resistance, and good clean-in-place and sterilize-in-place (CIP/SIP) characteristics.

Working for Lobe Pump
Lobe pump are similar to external gear pumps in operation in that fluid flows around the interior of the casing. Unlike external gear pumps, however, the lobes do not make contact. 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, pressure is limited by bearing location and shaft deflection.

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 — it does not pass between the lobes.

Finally, the meshing of the lobes forces liquid through the outlet port under pressure.
Lobe pump are frequently used in food applications because they handle solids without damaging the product. Particle size pumped can be much larger in lobe pump than in other PD types. Since the lobes do not make contact, and clearances are not as close as in other PD pumps, this design handles low viscosity liquids with diminished performance. Loading characteristics are not as good as other designs, and suction ability is low. High-viscosity liquids require reduced speeds to achieve satisfactory performance. Reductions of 25% of rated speed and lower are common with high-viscosity liquids.
