Question 1

What is progressive cavity screw pump?

Accepted Answer

A progressing cavity pump is a type of positive displacement pump and is also known as a progressive cavity pump, progg cavity pump, eccentric screw pump or cavity pump. It transfers fluid by means of the progress, through the pump, of a sequence of small, fixed shape, discrete cavities, as its rotor is turned.

Question 2

What is the difference between progressive cavity and screw pump?

Accepted Answer

These differ from a progressive cavity pump in that they are typically used for pumping lubricating fluids. Screw pumps are all metal pumps and are typically used for nonabrasive fluids. They also can pump at much higher discharge pressures that a progressive cavity pump.

Question 3

What is a progressive cavity pump used for?

Accepted Answer

A progressing cavity pump excels when handling highly viscous fluids which are required to be moved long distances (discharge pressure up to 48 bar). Typical fluids may include slurry, mashes, pulps, dough from waste water treatment plants, anaerobic digestion facilities and paper recycling plants.

Question 4

What are the progressive cavity screw pump parts?

Accepted Answer

Progressive cavity screw pump parts are the components that make up a pump, such as the rotor, stator, shaft, seals, bearings, coupling, and drive motor. They work together to move fluids using a rotating screw-shaped rotor and a helical-shaped stator.
