Five Common Causes Of Damage For Submersible Water Pumps

Posted on

If a submersible water pump, such as those from a place like Coast Water Well Service Inc, is an important part of your construction project, you need to make sure your pump remains in good condition to stay productive and improve your company's bottom line.

Many submersible water pump malfunctions can be prevented by effective worksite design, equipment maintenance, and equipment inspections.

The following are five common causes of damage for submersible water pumps that you may be able to prevent with adequate vigilance and awareness:

Running of the pump with a low water level

If a pump operates in a situation where it cannot draw adequate amounts of water in, cavitation can occur. This causes damage to both the pump's diffuser and impeller.

Known as dry running, this can eventually destroy the entire pump and will dry out seal rubbers so that they will be likely to develop cracks that will let water seep through. 

Latex or other non-biodegradable material in water

Water that goes through a pump must be kept pure to prevent malfunctions. Any non-biodegradable substance can clog up a pump. A bad clog can completely destroy a submersible water pump.

The best thing to do to prevent malfunctions due to latex or other non-biodegradable materials in water is to install a filter. Filters can be fitted to submersible pipe design to ensure the purity of water and the efficiency of submersible pump operation. 

Lack of discharge piping

Discharge piping prevents and minimizes friction in a submersible pump system. Without discharge piping in a submersible water pump, dead heading can quickly occur.

This is a situation where a pump exhibits excessive vertical head and a great deal of stress is put on the pump shaft. A lack of adequate discharge piping can cause the pump shaft to break completely. 

Disconnected or damaged cable

Cables connecting components of a submersible water pump should be regularly inspected for damage.

Damaged cables can allow moisture into the pump that will detract from its efficiency and lead to malfunctions. It's especially important to inspect the seal arrangement of the cable to ensure that the air seal is not ruptured and letting in moisture.

Backwards rotation of the motor

Sometimes, improper wiring of a submersible water pump can make it so that the motor runs in the wrong direction. This will drastically reduce the efficiency of the pumping mechanism. Not only are efficiency issues seen, but malfunctions including cavitation and impeller problems can result.

It's important to inspect a submersible pump to make sure it rotates in the right direction to avoid reverse rotation malfunctions.
