Lobe Pump by Rattan Industrial India Pvt. Ltd.

We manufacture, export and supply precision engineered Lobe Pump. Designed in numerous specifications, our Lobe Pump offers a variety of lobe options including single, bi-lobe, tri-lobe (shown), and multi-lobe. It is also used to handle slurries, pastes, and a wide variety of other liquids. Lobe Pump is extensively used in a variety of industries such as pulp and paper, chemical, food, beverage, pharmaceutical, and biotechnology. It is widely acclaimed for superb sanitary quality, high efficiency, reliability, corrosion resistance, and good clean-in-place and sterilize-in-place (CIP/SIP) characteristics. Rattan lobe pumps are used in a variety of industries including, pulp and paper, chemical, food, beverage, pharmaceutical, and biotechnology.

How It Works:Lobe pumps 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 pumps are frequently used in food applications because they handle solids without damaging the product. Particle size pumped can be much larger in lobe pumps than in other positive displacement pump types. Since the lobes do not make contact, and clearances are not as close as in other positive displacement pump, 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. Reduction of 25% or rated speed and lower are common with high-viscosity liquids.
