What is a Submersible Water Pump?

Submersible water transfer pumps are simply pumps that can be fully submerged within a fluid that requires pumping. They were originally developed in Europe and their use spread to the USA in the 1950s. While some people had initial reservations about the reliability of this type of pump, it proved to be highly dependable and highly successful. Today, submersible pumps are available in a wide range of different sizes and can be used in a wide variety of commercial, residential, and industrial applications.

A complete unit that’s entirely encased

A submersible pump is a complete unit: the motor, electrical and mechanical controls are entirely protected by a cover and frame. The motor and turbine bowl are directly attached to each other, and the power is supplied directly to the motor via waterproof cables. There must be a considerable amount of liquid running continuously through the pump in order to maintain the proper temperature and ensure that the system doesn’t overheat. To safeguard the longevity of a submersible pump, it is fitted with a cut-off mechanism that is designed to protect the pump from overload. In the event of a motor stalling, the power will be cut immediately to protect the motor windings from damage.

As previously mentioned, this kind of pump is available in a variety of dimensions to suit many different applications. The smaller pumps range from 0.75kw to 2.2kw and are suitable for use within residential and light commercial settings. These small pumps are usually able to accommodate solids up to a top diameter of 55mm. For industrial and construction applications, heavier duty pumps that can cope with waste and solids up to 65mm are usually required. The pumps can be installed singly or by fitting two pumps together. The dual system is usually the preferred option for industrial applications as it not only offers a greater capacity, should this be needed, but a second pump provides backup should one unit fail. It also means that there is less wear and tear on each individual pump which increases the longevity of the system.

In addition to fully submersible pumps, semi-submersible water pumps are also available. These are especially suitable for draining containers, barrels and basins and are designed to convey corrosive or abrasive products. Once again, they come in a variety of sizes to suit different applications and are an easy-to-maintain option that is also extremely cost-effective to operate.

The benefits of submersible pumps

There are many benefits of using a submersible pump, the main one being that it can be used in areas that are located below ground level. They’re a great choice for use in areas that are susceptible to flooding and particularly useful in areas where contaminated water may damage a conventional pump motor. They’re also ideal for areas where space is limited or for use in deep wells. As they are practically inaudible when working, they’re the perfect solution for areas where a quiet pump is required.

The pump of choice for many domestic and industrial applications

Pumps that are submersible are highly efficient, safe and cost-effective pieces of equipment that can be used for multiple applications in multiple settings. They’re also extremely reliable and extremely long-lasting. They’ve come a long way since they were first introduced and are now routinely used for situations where a pump is needed in a setting that’s located below ground level or when the pump must be submerged in liquid.
