Progressive Cavity Pumps
Tips & Advice to help you make your decision on Progressive Cavity Pumps
Progressive cavity pumps function by collecting fluid in small cavities that exist around a screw-shaped mechanism. The fluid is moved along the pump as the rotor is turned. When the amount of fluid being handled needs to be closely measured or the fluid is viscous and cannot handle a great deal of shearing or compression, these types of pumps are ideal to use. When liquid is pumped through a progressive cavity pump, the mechanism turns and acts as a motor. This is useful to provide extra power when drilling a well, for example.
Progressive cavity pumps can be used in almost any industry, although they are often used in the food and beverage, oil, sewage, and paper industries. The processing of produce and meats require the use of progressive cavity pumps for both processing and waste disposal. In the dairy industry, these types of pumps are used to gently convey milk products without affecting their integrity. Progressive cavity pumps are integral in the sewage and waste treatment industry, both for transporting and processing industrial and municipal waste.
It is important to use a pump that guarantees quality and safety for your industry. When conveying hazardous liquids or those that require delicate handling, you will find it necessary to use these types of pumps. You can find out more about progressive cavity pumps at Business.com.
Progressive Cavity Pumps Key Terms
Address your manufacturing needs by learning progressive cavity pumps key termsBy Apryl Beverly Learning about progressive cavity pumps key terms can help you take care of difficult pumping situations. Progressive cavity pumps are positive displacement pumps that can be used to handle small metering and dosing, as well as high volume pumping. These pumps can be used to move nearly any fluid or solid. The following progressive cavity pumps key terms will help you learn what you need to know to efficiently manage your pumping needs.
Stators
Stators are progressive cavity pump components designed to allow unobstructed, seamless feeding to rotors. Stators can be made from iron, rubber, stainless steel, plastic, or various other materials.

Rotors
Rotors are located on the external part of the pump and work in tandem with stators to keep fluid flowing at a steady pace while the pump is in motion. Rotors are made from a variety of materials such as stainless steel or chrome plated hardened steel.

Pin-type universal joint
The pin-type universal joint is used to facilitate motion in the progressive cavity pump rotor. Progressive cavity pumps are manufactured with two wear-resistant pin joints attached to the rotor or the plug-in shaft head.

Discharge flange
Discharge flange is a normal connection designed to match the discharge pressure of pumps. The discharge flange ensures that progressive cavity pumps properly self-clean, optimizing performance.

Best efficiency point
The best efficiency point is the measuring point used to determine optimal flow control of progressive cavity pumps. For best performance, progressive cavity pumps should be run to the left and right of the best efficiency point.
