Sanitary bare shaft lobe pump

Bare shaft pumps are pumps that require no drive and range in size from 1" to 10". The flow range is 0.05-50.4L/r. The first choice in pump family to transfer the liquid which has high viscosity, high denstiy, high solid and strong corrosion. Protect the original product without damage.

Products Details

Bonve sanitary bare shaft lobe pump are self-priming, valveless, positive displacement pumps. With the characteristics of low rotation speed and high output torque, pump shows his talents to transfer high viscosity liquid products. Its unique working principle works with a strong drive system, ensure that the pump can output a strong driving torque at low speed, can guarantee continuous, non-stagnant transferring, and ensure that the transferred material not damage, viscosity can be as high as 1500000CP.

                                     

Working principle


Bonve sanitary bare shaft lobe pump


Bi-wing rotor diagram



Tri-lobe rotors diagram




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.

Rotor types


According to the different medium, Bonve rotor designed has Single-wing, Double-wing, Tri-lobe, and Multi-impeller type, and all of these rotors can be interchanged in one pump.

Seal types


According to the different characteristics of the medium, Bonve offers the mechanical seal with different material and structure. The normal types used are single face and double-face.
