Classification and Types of Pumps

Classification of pumps

The pump is a mechanical device used for raising liquid from lower level to higher level. This is achieved by creating low pressure at the pump inlet and high pressure at the pump outlet. Due to low inlet pressure, the liquid rises from where it is available. High outlet pressure …

NPSH of Pump

NPSH

In a centrifugal pump, the pressure of the fluid at all points within the pump must remain above saturation pressure. Otherwise, cavitation occurs in the pump. Net positive suction head (NPSH) determines the adequate pressure of the fluid to avoid cavitation. The total suction head in meters absolute determined at …

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 …

Centrifugal Pump Working Principle

Centrifugal Pump

Centrifugal Pump Working Principle: Centrifugal pump uses centrifugal force to transfer fluid (Liquid & gas) from one pressure to higher pressure or one place to another place with the help of pressure difference. Fluid enters the pump at the center of the impeller. The rotating action exactly flings (throws) the …
