The Advantages of Submersible Pumps

October 2022

As their name suggests, submersible pumps are often made to be immersed underwater. These pumps are used by many industries, including homeowners, for wet wells, irrigation, oil production, and other purposes. A submersible pump often referred to as an electric submersible pump (ESP), is a machine with a hermetically sealed motor tightly connected to the pump body. The fluid that is to be pumped is immersed beneath the entire system.


The primary characteristic that sets apart a submersible pump from other pumping equipment is that it stays immersed in water. Since the internal components are entirely sealed off and do not come into touch with any foreign substances, you may install this pump inside a tank, well, or any other kind of container without having to worry about it being damaged. A submersible pump's motor is enclosed inside an oil-filled container and directly attached to the pump's body. Since the motor is kept sealed and insulated while it is powered by electricity, there is no danger of electrocution. 


In general, submersible pumps are very dependable and effective in challenging environments. They are constructed with durable iron castings and epoxy to prevent corrosion. They are widely used in Sewage Treatment, Wastewater Management, Wells, Mining, and Oil & Gas industries. They are mainly popular owing to the benefits that they offer.


Energy-Efficient


The flow range in which submersible well pumps typically operate is relatively tiny. They are always multistage pumps to suit a wide range of good depths. A more bottomless well requires more stages and higher pressure to achieve a static head. Manufacturers of pumps can produce very effective pump designs by matching the number of stages with a tolerable small flow range. A skilled well driller's correct measurement of the well performance and the pump's proper sizing on the well are the keys to achieving the most efficient pumping application.


No Priming Required


Additionally, submersible pumps are employed when it is challenging to prime a typical end-suction centrifugal pump. A submersible pump does not require priming because its suction input is underwater. Remember that a flow induction sleeve must be used to compel water to flow through the motor when utilizing a submersible well pump in an application other than a well (such as a pond, wet well, stream, etc.) to prevent overheating.


Designed to Manage Solids


Most submersible pumps are made to handle both liquids and solids without locking up while in use. It can be perfect for emptying an old well or pumping out a flooded basement. Selecting a submersible pump that promotes its ability to handle solids will help you make a long-lasting buy.
