Rotor pump lobe pump

Rotary lobe pumps are positive-displacement type pumps that use two or more lobes rotating around parallel shafts in the pump’s body to move liquids. They are widely used in the hygienic processing industries, including food & beverage processing and biopharmaceutical manufacturing.

Working Principle of Rotary Lobe Pump:

The rotary lobe pumps we also called them lobe rotor pumps. They are one popular transfer pump to conveying the food, beverage, pulp and paper, chemical, pharmaceutical and so on. The rotor lobe pump relies on two synchronously rotating rotors that generate suction (vacuum) at the inlet during the rotation. Thereby sucking in the material to be conveyed. Both rotors split the rotor chamber into different spaces. Then operate in the order of 1-2-3-4. The medium is delivered to the discharge port. In this cycle, the medium (material) is continuously transported out by the source.

Different Kind of Lobe Options for the Rotor Lobe Pump

1.Single Lobed Rotor:

More suitable for conveying media which containing large granular materials. The breaking rate of large granular materials is low. But on other hand it is not popular one for used, Because its pulsation is large and pressure is low, also the volume is small for the space of transferred materials.

2. Two-Lobed Rotor ((/Butterfly Rotor)

More suitable for conveying media which containing small and medium-size granular materials. The breaking rate to these materials is low and getting slightly pulsating. The volume is a little less than three-lobed rotor for the space of transferred materials.

3.Three-Lobed Rotor

It is widely used one rotor. The volume is bigger than other type of rotors for the space of transferred materials. Also each performance is higher than other rotors. Just it has a certain rate of breakage to the particulate materials on the transport way.

4.Multi-Lobed Rotor(4-12)

The volume is more smaller for the space of transferred materials and breaking rate more higher when the quantity of rotary vane of rotor be increased, . Just the transport way more stable.

Character:

1,There Is A Certain Gap Between Rotor And Rotor, No Friction Coefficient,So Pump Have A Long Service Life Time.

2, It Is Easy To Install And Disassemble,And It Is Convenient To Maintain, Clean .There Is Less Wearing Parts.

3, High Efficiency And Energy Saving, Stable Transportation, Low Failure Rate, No Leak Sealing And Low Noise.

4, The Viscosity Of The Transportable Medium Is ≤2000000 Cp, And The Pump Can Transfer Slurry Containing 70% Solids.

5, It Can Transport Gas, Liquid And Solid Three-Phase Mixture Materials.

6, With Vfd, The Flow Can Be Adjusted At Will, And The Pump Can Be Used As A General Metering Pump.

7, If Need,We Can Do The Pump With Heating Jacket.

8, Applicable Temperature: -50 °C -250 °C.

9, Types Of Inlet/Outlet Connection: Flange Joint,Threaded Connection; Quick Connection.

10,Seal Type: Mechanical Seal And Packing Seal.

ADVANTAGES OF ROTARY LOBE PUMPS

Since the pump’s lobes do not come into contact with each other, lobe pumps can move solids suspended in slurries (such as cherries or olives in food processing applications) without product damage.

The gentle pump action further minimizes product degradation.

Can handle larger sized particles than may be pumped with other types of positive displacement pumps.

May be easily cleaned using either clean-in-place (CIP) or steam-in-place (SIP) methods, making them ideal for hygienic processing applications.

Highly efficient for pumping very viscous liquids.

Offer accurate and consistent fluid output that is unaffected by changes in head pressure, assuming sufficient fluid viscosity.

The fluid flow can be increased or decreased by controlling the drive speed.

If wetted, rotary lobe pumps are also self-priming, and can run dry for long periods of time (assuming the pump’s seals are lubricated).

Generally easy to maintain.
