Npsh progressive cavity pumps
WebNOV manufactures Mono™ progressing cavity pumps and pump parts and has a wide product range suitable for the pumping of fluids within the waste water, chemical, food, beverage, paper, mining, mineral processing, marine, agricultural and oil and gas sectors. WebEfficiency is less affected by pressure. Positive displacement pumps can be run at any point on their curve without damage or efficiency loss. Suction lift. Standard centrifugal pumps cannot create suction lift. Positive displacement pumps create a vacuum on the inlet side, making them capable of creating suction lift.

Web2 mei 2024 · The required NPSH hsv for pressure decreases at the pump impeller inlet to the minimum pressure, which should be lower than hsv. Keeping an eye on fluid temperature will also keep cavitation at bay because the conditions for vaporization become more favorable as liquids heat up. WebProgressing cavity pumps belong to the group of positive displacement pumps. The main components are a rotating rotor and a stationary stator. The rotor, hinged or elastically attached on one side, is a round-threaded screw. On the output side, the axial position oscillates. The hollow stator is elastic and has the same pitch length as the rotor.
