Rotary lobe pumps are positive-displacement type pumps that use two rotating around parallel shafts in the pump's body to move liquids. There are various designs of rotor, including bi-wing, metallic and rubber coated and multi-lobe options. Providing low shear and gentle handling of the liquid, thereby minimizing product degradation, rotary lobe pumps are also easy to clean out of place (COP) clean in place (CIP) or strip clean between operations for batching applications. The pump’s compact dimensions disguise operating expectations in respect to its displacement flow volume.

The Operating Principle of Rotary Lobe Pumps
Rotary lobe pumps function by synchronizing interlocking, lobe-shaped rotors with high precision timing gears to move a fixed volume of fluid through a sealed chamber. These gears prevent rotor contact, allowing the pump to handle various fluid types including viscous and non-lubricating fluids while minimizing wear. The curved lobes ensure minimal dead areas in the chamber, enhancing cleanliness and maintenance ease.
The pump operates on a positive displacement principle, where bi-directional rotor movement creates cavities to draw in and expel fluid, achieving a low pulsation flow suitable for sensitive fluid handling. Rotary lobe pumps accommodate flow rates up to 1000 m³/h, temperatures up to 150°C, viscosities up to 100,000 cst, and pressures up to 30 bar.
Application where Rotary Lobe Pumps are Used
Rotary lobe pumps are prevalent in industries like food processing, personal care, pharmaceuticals, and chemical processing. They are vital in applications requiring gentle handling of media to prevent shear and damage, accommodating diverse media characteristics from non-abrasive dairy products to abrasive chocolates and sauces. The consistent, low pulsation flow supports seamless production lines, crucial in minimizing downtime and product waste.
