BONVE Food grade lobe pumps are to be found in numerous processes, where their reliable low shear flow characteristics are ideally suited to the transfer of media such as starch paste, tomato paste, chocolate, sugar syrup, honey, jam, sauce products. We select the pump according to your characteristics of medium and condition of the technological requirements, bring you the best pump for your critical process, satisfied by you and your customers.
BARE SHAFT PUMP STRUCTURE
WORKING PRINCIPLE
The even rotation of the rotor pair creates a vacuum on the priming side of the pump, which can be defined by the direction of rotation of the drive. This vacuum draws the liquid into the pump chamber. With further rotation, the pumped medium is conveyed past the pump wall into the pressure area. Up to six chamber charges are displaced with each drive rotation– depending on the rotor type. When the rotor is at a standstill, the pump seals off almost completely.
PUMP ROTOR TYPE
Butterfly rotors: used to transfer liquid with middel or small particles, with low damage and low pulse. Capacity is smaller than tri-lobe rotors.
Tri-lobe rotors: Common type. Capacity is higher than other rotors, performance is better. But it has certian breakage to the particles.
PUMP STRUCTURE ADVANTAGES
PUMP TECHNICAL FEATURES
Sanitary Feeding Pump
All parts contacting with material are made of stainless steel which is conforming to sanitary standard.
Heating Jacket Design
Lobe pump with heating jacket preserves the heat, without coagulation when pumping liquid which is easy to be coagulated .
Water flushing or Oil-lubricated mechanical seal
Preventing equipment normal operation on the end surface of the mechanical seal from coagulation during feeding high viscosity liquid, and the service life mechanical seal in bad environment can be ensured.
Almost Have No Consumable Parts
There don't have any damage on the part during the rotor pump is operating (except mechanical seal), all parts contacting with material is made of stainless steel. A pair of rotors run synchronically during operating in a space with each other, no contact, there won’t be any damage in theory, so the rotor pump can work at temperature of 220℃ in all environments.
