What is rotery pump?

A rotary pump is a type of positive displacement pump that works by trapping fluid between rotating components and a stationary casing or housing. The rotation of the components produces a suction effect, drawing fluid into the pump and then pushing it out under pressure.

Rotary pumps are commonly used in a variety of applications, including industrial processes, chemical handling, oil and gas production, and wastewater treatment. They are typically designed to handle viscous liquids and are available in several configurations, including gear pumps, lobe pumps, and screw pumps.

One of the advantages of rotary pumps is their ability to deliver a steady flow of fluid, even at high pressures and over long distances. They are also relatively compact and can be used in systems that require a small footprint.

However, rotary pumps require regular maintenance, including lubrication and replacement of wearing parts, to ensure reliable operation. They may also be unsuitable for handling abrasive or corrosive fluids, depending on the materials used in their construction.
