Gear Reduction Rotor Pump is a common industrial pump, usually used to transport liquids or viscous substances. Its working principle is to use gear transmission and the rotational motion of the rotor to achieve the suction and discharge of liquid. This type of pump usually consists of one or more gears and rotors, whose movement creates a vacuum and draws liquid in from the inlet and then discharges the liquid through the discharge port.

Rotary Gear Lobe Pump

Gear Reduction Rotor Pump are often used in applications requiring high pressure and high flow, such as the delivery of lubricating oil, hydraulic oil, fuel, etc. Due to its simple structure, reliable operation and high efficiency, it is widely used in industrial fields.
