Pumps and their Applications

An example of a one of the oldest pumps is an Archimedes or Screw Pump.

This pump is designed for moving extremely large volumes of water under a low

suction lift and low discharge head pressure.

As the screw turns, the veins of the screw move the water up the gradient to the

higher receiving channel.

These pumps are often used for high volume water demands. This type of pump

is simple and reliable, but requires a large footprint, with limited discharge head

capability (or height the water can be lifted).
