What is Pump Cavitation?

Pump Cavitation

In a centrifugal pump, the flow area at the eye of the pump impeller is usually smaller as compared to the flow area of the pump suction piping. When the pumped liquid enters the eye of the pump, the decrease in flow area results in an increase in flow velocity. …

Difference between Centrifugal pump and Reciprocating pump

Difference between Centrifugal pump and Reciprocating pump

Difference between Centrifugal pump and Reciprocating pump Centrifugal pump is a rotodynamic pump that uses kinetic energy to transfer fluid from low pressure to high pressure while the reciprocating pump uses a piston (suction and discharge stroke) to transfer fluid. Centrifugal pump is the most popular pump as compared to …

Reciprocating Pump Working

Reciprocating Pump

Reciprocating Pump Definition: The reciprocating pump is a positive displacement pump works on the principle of a reversing piston motion within a cylinder. During suction stroke, it sucks liquid and during discharge or return stroke, delivers liquid under pressure. One way valve installed on both suction and delivery side to …

Positive Displacement Pump

Positive Displacement Pump

Positive Displacement Pump Working Principle: Positive displacement pump trap liquid at the suction of the pump and pushes that quantity of liquid out to the discharge of the pump. The pressure produced by a positive displacement pump depends upon the amount of force exerted on the piston. Positive displacement pump …
