Bonve 4G pumps
Bonve stainless steel rotary lobe pumps are designed basedon the exploration of more than 3,000 fluidsin various industries. They are particularly pumping for high viscosity, high solids, sanitary and corrosive fluids.For more than a decade,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.
Main features
- Interchangeable rotors, one pump multi-purpose.
- Targeted seal for specific application, ensure zero leakage.
- Compact structure, easy assembling and disassembling
- Maintenance in place, easy cleaning, CIPable and SIPable.
- Few wearing parts, low maintenance.
- 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 rotary 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.

Seal types
According to the different characteristics of the medium, you can have the Single-face balancing mechanical seal, Double-face water cooled mechanical seal, Heat resisting bellows mechanical seal, etc. Targeted seal used ensures zero leakage. All these types can be universally interchanged.
Rotor types
According to the different medium, the rotor designed has Single-wing, Double-wing, Tri-lobe, Four-impeller and Multi-impeller type, and all of these rotors can be universally interchanged.
Lineup
To meet the different requirements of site installation, Bonve designs a variety of pump structure as below. We also can make as per your request.
