What does a pump do?
A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action, typically converted from electrical energy into hydraulic energy. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps.
How does pump increase pressure?
Centrifugal pumps increase the pressure of the liquid by using rotating blades to increase the velocity of a liquid and then reduce the velocity of the liquid in the volute.
What is an overhung pump?
An overhung centrifugal pump uses one impeller installed on a shaft that is suspended at one end by bearings. Between bearing centrifugal pumps are favoured over overhung centrifugal pumps whenever higher flow rates, higher pressures, and heavier loading of the pump will occur.
