Rotary Lobe Pumps For Soy and Corn Oils

Soy and corn oils, typically referred to as "vegetable" oil, are a key part in both industrial and every day food preparation. Bonve Rotary Lobe Pump has multiple pump options for the processing of both soy and corn oil.Soy and corn oils are similar to other edible oils, including palm, peanut, and sunflower oils. The three main processes for producing these oils are extraction, refinins, and blending.

Bonve Rotary Lobe Pumps are typically found in byproduct applications related to the processing of edible oils. These include gums, soapstock, and free fatty acid distillates - as well as product transfer, blending, and loadout operations.


Similar to other edible oils like:

1. Palm Oil

2. Peanut Oil

3. Sunflower Oil

Oils are produced through extraction, refining, and blending

Pump Benefits

1. The pump can be used to transfer thin or thick fats with high efficiency.

2. Low working speed results in gentle, low-shear operation.

3.All the contact parts expect 0-rings are made of stainless steel, sanitary grade.

4. No contact parts and Robust design for long service life.

5. Easy maintenance due to self-setting, front-loading seals.

Working Principle

Bonve lobe pumps basically consist of two lobe rotors, which rotate synchronously driven by a pair of synchronous gears in the gearbox. The rotors are driven by the main shaft and sub-shaft to rotate in a synchronous reverse direction, which changes the pump capacity, builds up high vacuum and discharge pressure, thus an efficient pumping is formed. Gap is kept between the rotors and between the pump casing, no friction, long life, no damage, no physical and chemical reaction to the pumped products.
