Which Type Of Pump Do I Need? – Submersible Pumps

In this month’s ‘Which type of pump do I need?’ guide we are looking at the different types of Submersible pump to continue on our quest to help you decide which type of pump is best for your application. Last month we covered Process Pumps.

A submersible pump is a self-contained unit with a built-in sealed motor, which pumps effectively when completely submersed in fluid. Submersible pumps are used in a variety of applications including sewage and drainage.

Grinder Pumps

A Grinder Pump is a centrifugal pump equipped with a grinder system at the pump inlet, which cuts larger particles and fibres into a homogeneous wastewater mass. As a result, the risk of clogging is reduced to a minimum. However, this pump is not suited to pumping media with a high content of sand and they consist of more wearing parts, therefore requiring additional ongoing maintenance and spares.

Applications: For sewage, when there’s a high head application and pump systems with smaller pipe diameters, where the flow is typically lower, for example, remote areas or single houses.

Borehole Pumps

Selecting appropriate submersible borehole pumps is a specialist area. A submersible water pump for boreholes needs to work effectively when it’s submerged in water. This means its built-in motor must be completely sealed. Boreholes are increasingly used by organisations that consume a high volume of water as they access water from the plentiful supplies under the earth’s surface. However, there are many variables including the depth of the water and its properties. If you choose a submersible Borehole Water Pump that’s not strong enough for the job, it will lack efficiency. The right Borehole Water Pump will play a key role in energy saving and in water-efficiency.

Applications: produce growers, car-wash companies, swimming pool operators, mining, farming, deep wells, rainwater reticulation and petroleum capture.

Vortex Submersible Pump

The Vortex Impeller creates a revolving mass of water, which forms a whirlpool. As a result, similarly to a Grinder Pump, a vortex impeller minimises the risk of clogging. However, Vortex Pumps are a better choice when the pumped liquid has a high content of sand.

Applications: sewage & stormwater, particularly when dealing with high sand content.

Submersible well pump

For deep wells that require a large amount of lift, Submersible Well Pumps are the best option. A submersible pump functions differently from a jet pump in that it pushes water upwards instead of pulling the water from the well. Submersible pumps are much more efficient than jet pumps, and they are perfect for situations where there is a wide separation in elevation between the water level and the pump.

Applications: instances where water needs to be drawn from a deep well.
