Rotor pump is a volumetric pump that is driven by a pair of gears with a gear ratio of 1 to drive two rotors to achieve synchronous reverse rotation, creating a vacuum at the inlet during the rotation to draw in the liquid to be conveyed. It is also commonly referred to as a non-contact rotor pump.
The principle is that the two rotors in the pump are driven by two synchronous gears to rotate and complete the suction and discharge of liquid. The two rotor surfaces do not touch each other, so the viscosity of the applicable media is very wide, from low viscosity to semi-solid and particle-containing media.
The working principle of the rotor pump determines the high reliability in improving the viscosity reduction of the overpumped medium under high pressure, high temperature, high shear, stable quality, and shear-sensitive medium safety. Rotor pump has a simple working principle, small volume, light weight, low cost, safe sealing, no pollution, etc. It is not only suitable for oil-liquid media transfer, but also has a wide potential market in daily chemical, petroleum, pharmaceutical, food and other industries. Therefore, rotor pumps can perfectly replace screw pumps and centrifugal pumps in some occasions.
