Submersible pumps are one of our bestsellers at Pump Sales Direct. Their popularity, in some part, derives from their versatility. Equally at home fighting fires (their cables are flame retardant) as they are handling seawater and extracting oil from thousands of feet into the Earth’s surface, submersible pumps have a wide range of uses. And having already brought you a guide explaining the ins-and-outs of how they work just a month ago, we thought it would only be natural to follow it up with a post explaining the different scenarios in which they can be used. To learn about the ways in which submersible pumps are used and why, carry on reading.
Supplying crops with water is as important a job as any – one that, in many cases, falls to submersible pumps. The future health of our food depends on the efforts of submersible pumps. Tasked with moving masses of water from one location to another, often with metronomic precision, submersible pumps certainly have an important and difficult undertaking on their hands. There are two forms of submersible pumps, or rather compositions of submersible pumps that are typically used for irrigation – deep-well submersible pumps and vertical turbine pumps. The major difference between the two is the location of the motor. In vertical turbine pumps, the motor is installed above ground and connects to the pump itself via a line shaft. Deep-well submersible pumps have a slightly more intricate and complex design – their motor accompanies them submerged in the water – and is designed accordingly to cope with the high pressure.
Drainage and wastewater
Multi-stage submersible pumps’ ability to pump water upwards against the action of gravity makes them a popular choice in the sewage and wastewater industries. In packaged pump stations, where drainage by gravity is not possible, submersible pumps have become particularly invaluable – so much so that they can be considered to have had a marked impact on the sewage pumping industry over the last fifty years. Their use isn’t just confined to the commercial world though; they are just as useful domestically. For homeowners with a swimming pool or a pond that needs draining, a quality submersible pump is a valuable ally.
The action of submersible pumps is essentially the same no matter what fluid it is pumping. While minor alterations may be made to account for differences in viscosity, submersible pumps appeal to those in the oil industry for the same reason they appeal to those in the wastewater field – submersible pumps are able to act against gravity. Where the use of submersible pumps with oil differs from those that are designed to handle water, is their ability to endure the variations in viscosity, temperature and depth that oil extraction often demands. Depths of over 4000ft are common and electrical submersible pumping systems are assembled to maximise durability and productivity even at such huge depths.
As you can see, submersible pumps have a plethora of potential uses – both commercial and domestic – and you will find a range of the highest quality submersible pumps here. If you have any questions about specifications or otherwise, please call or email us, we are happy to help.
