How Rotary Pumps Work
Rotary pumps are positive displacement pumps that use rotary motion instead of reciprocating motion in their pumping action. There are several types of rotary pumps, including vane pumps, lobe pumps, and gear pumps. Each type works differently but all of them are based on the same positive displacement principle.
Vane pumps work by using vanes mounted to a rotor that rotates inside a cavity. The vanes move between the rotor and the walls of the cavity, creating a vacuum that pulls the liquid into the pump. This liquid is then transported around the rotors and eventually discharged.
Lobe pumps use counter-rotating intermeshing rotors to create suction. The suction pulls the liquid into the pump and transports it around the rotors. These pumps are commonly used for applications where high viscosities make centrifugal pumps uneconomical.
Gear pumps also rely on a positive displacement principle. These pumps consist of two gears that are driven by an electric motor. As the gears rotate, they create a vacuum that pulls the liquid into the pump. The liquid is then transported around the gears and discharged.
Rotary pumps are versatile and can be used in a variety of applications. They are particularly useful for applications that require high viscosity fluids and for those that require handling “wet” oil. Each type of rotary pump works differently, so it is important to understand how each works in order to determine which type is best for a particular application.
