Attributes of Submersible Pumps

The Different Attributes of Submersible Pumps 

Pumping liquid from a large body of water requires a pump solution that will be able to handle the quantities of liquid efficiently. Where most pumps are placed outside a body of water to pull water to the surface, submersible pumps are submerged to push water to the surface, making them ideal for several applications. With the submersible pumps available through Prochem Chemical Pump Manufacturers, draining or reducing water levels in the commercial, industrial, residential, and agricultural sectors has never been simpler.

Portable or Fixed

Submersible pumps are available in a variety of sizes, depending on whether they are needed for reducing groundwater, pumping water from groundwater to be used as drinking water or for fire-fighting, pumping dirty water, or draining wastewater. Portable smaller units are used within homes or light commercial settings and can accommodate solids in liquids up to 55 mm in diameter. Larger submersible pumps, used for industry and agriculture, are normally fixed in place and can handle solids up to 65 mm. The minimum and maximum depth that these pumps can be submerged is determined by the use.

How Deep Can Submersible Pumps Go?

Ebara Pumps - Submersible Pumps

In wastewater and sewage treatment, submersible pumps are needed to direct the flow of sewage water toward a treatment facility without losing its watertight integrity at depths of approximately 20 m. When mounted on a guide rail system, these pumps can be easily removed for inspection or service should the need arise.

The agricultural sector relies heavily on well or borehole water as their main water source. The depth that a submersible pump can be submerged depends on how deep the water table is. Reaching depths of up to approximately 457 metres below ground, submersible pumps can continuously or cyclically push water to pipelines for irrigation.

As mining operations require vast quantities of water to be removed whilst extracting product, dewatering submersible pumps need to reach depths of approximately 244 metres. As these pumps are relatively simple to install and self-priming, they require no additional ventilation or watertight doors. They are being used more frequently for the dewatering of open pit mines as well as underground mines.

From minimum depths of 15 cm or open water, submersible pumps can supply water in the event of incidents, such as fires.

Operating Cycles of Submersible Pumps

These pumps are designed to remain submerged, operating continuously from anywhere between 6 to 24 hours. However, it is advisable with some applications to have them running intermittently to extend their shelf-life. Increasing the longevity and running cycle of the pump depends on different factors, such as:

  • The quality of the pump
  • Electrical supply
  • The length of time the pump is being run for

Ensuring That the Right Sized Pump is Used for Application

For submersible pumps to operate effectively, the pump must have significant volumes of liquid running through them at any given moment. This maintains the correct operating pressure of the pump and prevents the system from overheating.
