Proper Maintenance of Self-priming Pumps

industrial centrifugal pumpHave you ever thought about how the fluid pumping process in your industrial or mining applications works? The pump utilises centrifugal force to produce a pressure difference in a particular fluid. This pressure difference causes the pumping action.

In applications where air interacts with water in impellers, it becomes hard for regular pumps to function, hence the need for speciality pumps. Self-priming pumps are among these advanced types, which mix air and water to form a resultant fluid that has the same characteristics as water. Maintaining these speciality pumps requires special care.

Cleaning the Impeller

When debris from the work environment accumulates in impellers, it causes blockage and lowers the pressure necessary for fluid movement. Removing the debris minimises chances of jamming and boosts pump performance.

Clearance around the Electric Motor

Pumps use electric motors that depend on air for cooling. Thus, your engine should have enough clearance for circulation of air. Eliminate any object around the motor and clean any present dirt or dust.

Inspect the Recirculation Ports

The ability of such pumps to prime depends on the proper functioning of recirculation ports. Any blockage around the recirculation ports will compromise the functionality of the pump. Regular cleaning of this port will ensure that your pump maintains its priming ability.

Look Out for Leaks in the Suction Line

Contrary to popular belief, these pumps require a small quantity of fluid in the suction line for proper priming. When there are obstructions in the line, they will trap air and affect the priming ability of the pump.

Self-priming pumps overcome the issue of air combining with water, which is prevalent in mining, industrial and construction applications. Proper maintenance of the pump will extend its durability.
