Over the years, Bonve has been focused on communication with customers and constantly optimize our pumps to be low maintenance, long-life cycle and environmental friendly, so far BONVE ROTARY LOBE PUMPS have been developed to the 4th generation (4G), which further extends the service life of the pump.
The extensive application of Bonve 4G pumps in various fields benefits from innovative structural design and large experience accumulation, featured interchangeable, easy maintenance and long life.
Interchangeable
- Interchangeable rotors, one pump multi-purpose.
- Targeted seal for specific application, ensure zero leakage.
Easy maintenance
- Compact structure, easy assembling and disassembling
- Maintenance in place, easy cleaning, CIPable and SIPable.
- 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.
