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.

Features of Movable Rotary Lobe Pump

1. High quality stainless steel materials of 304L and 316L can be chose for your lobe pump. the most important properties of these materials are high temperature resistance and corrosion resistance.

2. Rotary lobe pump getting the low noise and long service life cuz they are non-contacting between the rotors and driving gear, rotors and chambers,even between the impellers.

3. Lobe rotor pumps can convey the gas, liquid and solid these mixtures even their viscosity has up to 1,000,000 cp or used to handle 50% solids paste.

Rotary Lobe Pump Parameter:

Advantages of Movable Lobe Rotor Pumps:

1. Has a compact stucture and easy to maintenance.
2. Pass medium solids
3. No metal-to-metal contact
4. Shiftless transmission
5. Easy to move

Different Kind of Lobe Options for the Rotor Lobe Pump

KOSBEST Rotary Lobe Pump can offer the different kind of lobe options including single, bi-wing, tri-lobe, and multi-lobe. Rotary lobe pumps are non-contacting between the rotors and chambers. A large pumping chambers can allowing them to process the liquid, solid-liquid, paste even solid by constant and continuous of the output.

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.

Application of Rotary Lobe Pump:

Common rotary lobe pump applications include, but are not limited to:
• Paints and dyes
• Polymers
• Rubber and adhesives
• Pharmaceuticals
• Paper coatings
• Soaps and surfactants
• Food applications (a sample of these is referenced below)

Food and cosmetic products capable of being pumped by lobe rotor pumps.
