How to Measure the Total Head for a Centrifugal Pump
Centrifugal pumps are rated by flow output at various resistance levels. Charts provided by the manufacturers, called "pump curves," show the flow rate along the horizontal axis and the resistance level along the vertical axis. The resistan... Read More »

Why the centrifugal pump is called high discharge pump?
for a simple reason because it has high discharge than any other available pump. the centrifugal pump uses the centrifugal force to push out the fluid centrifugal force = (mass *velocity2)/radius. hence centrifugal force is directly proport... Read More »

A centrifugal pump develops suction by constantly maintaining a low pressure zone at the eye of the impeller, this drops causes a differential pressure compared to atmospheric pressure that can draw liquid in, creating a vacuum head. A reci...

A centrifugal pump depends on the velocity imparted to the liquid by the impeller to produce the increase in pressure you see at the discharge. This means if the fluid being pumped has a higher density then the pressure produced will be hig...

Thottling the discharge valve will increase pressure "developed" within pump. Static discharge pressure is the same as geodetic head, P = 80 m ~ 8 bar. Higher flow means higher power requirement, if the power too high, consequently the moto...
