POSITIVE DISPLACEMENT ROTARY LOBE PUMP 4G (4th generation)
Application for Adhesive
The production process of the adhesive is mainly to add various strengthening agents to neutralize several kinds of chemical products after high temperature reaction, and then carry out degassing and dehydration to form glue. There is still negative pressure during degassing and dehydration, so there are strict requirements on the self-priming of the pump. Bonve adhesive lobe pumps are based on application technology, and are specially customized for the gap, smoothness, and sealing of the pump according to different working conditions. Our adhesive lobe pump effectively solves a series of problems of the pumps used before in the production process of adhesives.
What Pumps We Offer?
Bonve offers the broadest range of its Rotary Lobe Pumps for adhesive. We named these pumps as adhesive transfer pump. As an excellent pump manufacturer, our hard technical barriers have become a powerful help for our Bonve pumps reform and innovation. So far, Bonve pumps have developed to the fourth generation and are mature.
Interchangeable
- Interchangeable rotors, one pump multi-purpose.
- Targeted seal for specific application, ensure zero leakage.
Easy maintenance
- Compact structure, easy assembling and disassembling
- Few wearing parts, low maintenance.
Long life
- All main parts proceed by CNC, high precision fabrication.
- No contact between the rotors, rotors and pump chamber.
- Six bearings with separate arrangement, high balance.
- Adjustable seal ring extends the shaft life.
- Axis key synchronous adjustment, no rotor collision problem.
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.
