W-type cryo rotary pump

Sturdy and simple structure, standard type W shape.

Outstanding performance for transporting all types of liquids! This is a highly versatile rotary pump that can be used for high polymer polymers, chocolate, asphalt, and more. There is also a stainless steel SW type for the wetted parts. Inside the casing of the rotary pump, there are two fan-shaped blades that rotate in sync via a pinion gear, with no contact between the blades themselves. Additionally, there is no contact with the casing or cover. As the blades rotate, the chamber pressure on the suction side (the pressure in the space between the two blades and the casing) decreases, allowing liquid to enter. As the blades continue to rotate, the liquid moves along the inside of the casing toward the discharge side. Furthermore, the blades interlock, and the liquid is expelled from the pump.
