Total Tools Water Pumps

1.       Centrifugal Water Pumps

Any pump that induces flow or raises pressure of a liquid which results in a pumping action are centrifugal water pumps. It is used in over 95% domestic and industrial applications as the preferred hydraulic pump. Centrifugal pumps are low in cost, maintenance and are simple to operate. As a result they are used universally.


2.       Peripheral Water Pumps

Also known as regenerative or turbine pumps, peripheral water pumps appear like centrifugal pumps. The internals are different in the way they can develop high discharge heads at low flow rates. The fluid in a peripheral pump is pumped into a peripheral channel, which is around the edge of the casing. The curves do not flatten as the fluid flow decreases which is unlike standard centrifugal pumps. With increasing pressure, the fluid moves along the circumference for the inlet to the outlet of the casing.

Peripheral pump application requires careful evaluation of the maximum pressures which can be developed at zero flow condition.


3.       Self-Priming Water Pumps

Standard centrifugal pumps can’t handle any air. Self-priming centrifugal water pumps prevent air binding by mixing it with water. This creates a fluid that is like pure water and can be pumped normally. The pump will then get rid of the air and move the water only like a standard centrifugal pump.
