Centrifugal pumps

Centrifugal water pumps for sale

Single stage centrifugal pumps are the most common pump for fluid transfer in high flow rate, low pressure installations. If a lower flow rate or a higher pressure is needed over what a single stage centrifugal pump can provide, a multistage centrifugal pump is a better suited alternative.Centrifugal water pumps are common single stage pumps, however due to the wide range of materials available centrifugal pumps can also be used for other low viscosity fluids such as fuel, oils and petrochemicals.

Pump Composition

Centrifugal pumps use rotating vanes called impellers, the impellers are closed in a casing and push fluid with centrifugal force. We can divide the pump into two main parts: a stationary part consisting of a casing (volute), stuffing box, and bearings. The second part: a rotating element which includes an impeller and shaft.

Pump Operation

Centrifugal pumps use kinetic energy to move fluid, this is done with a circular pump casing and an impeller.  A vacuum is created which draws fluid to the impeller through suction. The pump housing converts velocity of the fluid to pressure by containing and directing the fluid to the discharge valve. This is done by offsetting the impeller in the casing and maintaining a narrow space between the impeller and the casing at the cutwater. Centrifugal pumps can achieve very high flow rates by forcing fluid through without cupping it.
