Brief introduction
YL rotary lobe pump is self-priming, valveless, positive displacement pumps. With the characteristics of low rotation speed and high output torque, pump shows its 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.

Pump 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 Structure
Complete pump consists of bare shaft pump, coupling& shield, gear reduer with motor and baseplate. You can only have our bare shaft pump.
