what is a submersible pump
A submersible pump or sub pump, electric submersible pump “ESP” is a device that has a hermetically sealed motor tightly joined to the pump body. The full assembly is submerged in the fluid to be pumped.
The submersible pumps flick fluid to the surface, rather than jet pumps, which create a vacuum and rely upon meteorological pressure. Submersibles use pressurized fluid from the surface to send a hydraulic motor downhole, in the place of an electric motor, and are used in heavy oil applications with heated water as the motive fluid. The primary benefits of this type of pump is that it prevents pump cavitation, a issue associated with a high elevation difference between the pump and the liquid surface.
Types of submersible pumps
Various categories of submersible pumps are used in wells, tanks, and similar application. The main types of these pumps are explained below.
1- Grinder Pumps:
The sewage grinder pumps are designed to operate with raw sewage and solid discarded materials. Grinder pumps soften the solids utilizing their cutting blades before pumping the waste. While on a larger scale for sewage waste, a grinder pump functions similarly to a household garbage disposal. It pulverizes solids and other hard discarded material up into fine slurry and then transfers it into the sewer system.
This pump design is manufactured to be used in residential and commercial applications as well as high-pressure sewage systems including long-distance pumping, high lifts, and pressurized municipal sewer lines. For directly pumping into a septic tank, the utilize of a sewage grinder pump is not advised.
2- Bladder pumps:
In situations where high-integrity samples with low flow rates are necessary, and peristaltic pumping is not a feasible choice, the bladder pump systems provide an effective alternative to customers.
Utilizing a submersible stainless-steel pump along with a coupled controller/compressor at the well surface, the bladder pump system is utilized to control air pressure to direct water samples to the surface. Furthermore, using a disposable polyethylene bladder within the submersible pump ensures the prevention of air and water mixing.
3-Macerator pumps:
A macerator pump is joined to a toilet that grinds up solid discarded utilizing a high-speed rotational blade. It then pumps the discarded into the sewerage system.
Macerators are fabricated to pump out the discarded materials and wastewater from toilets without relying on a regular drainage system. They are employed in bathrooms located at a distance from the main drainage systems.
4- Utility pumps:
The submersible utility pumps are capable of removing standing water, clearing clogged sinks, draining window wells, and performing various other tasks. When choosing a utility pump, the most crucial factor to consider is portability. Utility pumps are best utilized in small spaces where conventional water pumps just won’t fit. The inlet size on the pump will tell you how fast you can pump the water through the pump and outflow it elsewhere. A utility pump with a float switch is great too because they automate the pump by activating and deactivating it in response to changes in water levels.
Urgent and semi-regular pumping applications are ideal for utility pumps, as long as the water does not have debris or solids in it. Utility pumps are not intended to pump solid items at all, so do not utilize one for cleaning dirty water with solids, and do not utilize this pump for sewage-type applications.
5- Condensate pumps:
A condensate pump is a centrifugal pump utilized in condensers to convey the condensed steam as water “called condensate” in a vacuum “near vapor pressure”. In an uncovered circuit, the condensate pump shifts the condensate into a tank “feed water tank”. Nevertheless, it sends the condensate into the boiler feed pump via a low-pressure feed heater in a closed circuit.
6- Booster pumps:
Booster pumps elevate the low flow of water in systems or industrial facilities and convey the water from a lake, pond, or storage tank for domestic or commercial purposes. For instance, a household that does not receive insufficient pressure from the city water source may require a pump to enhance the low pressure of the water flow. A hotel requires a large commercial booster pump to transport of water to the upper floors.
A booster pump is also utilized to re-pressurize water from a storage tank and distribute it throughout a home. For instance, in a rain harvesting system, water is collected in a storage tank. To utilize it for purposes like flushing toilets or washing laundry, the water must be transferred from the tank into the house.
7-Solids handling submersible pumps:
These submersible pumps can transport solid material through the pump without any obstruction or interference from entry to discharge. Spherical material with a diameter of 3 inches to 14 inches or more can move via these submersible pumps.
8- Borehole pumps:
Borehole pumps are centrifugal pumps conducted by a submersible motor. As long as they typically draw into the fluid straight without a suction line, they recommend being constantly submerged in the fluid.
These pumps are engineered as single and different-stage pumps joined to the submersible motor. Fall under the application, the motor can be located up or under the pump.
Submersible borehole pumps are connected in tank farms and as cavern pumps. Borehole pumps are more expensive than deep-well pumps.
9-Oil filled pumps:
These types of pumps are widely utilized in different places, including water lifting in wells as well as the water supply for agricultural forms, residential areas, factory drainage systems, and hill areas.
These machines can be posted in cool areas since oil cannot be frozen. The gelation and refurbishing of these pumps are simple. These pumps refer to the cleaning water such as the dams, pools, or rivers.
These pumps have a longer service life than water-filled submersible pumps, these pumps may have a circumjacent impact because of oil pollution. Additionally, they are more costly than water-filled submersible pumps.
10- Bottom suction pumps:
Bottom suction pumps are widely utilized for lake, pool, river, and mining dewatering. They are designed with a guide sleeve beneath the pump. These pumps use the water from the base and effectively confirm the high-quality cooling feature of the electric motor.
These pumps are campaign and emergency pumps. The establishment of bottom suction pumps is Ponder to be simple compared to other types of pumps.
11- Dry pit submersible pumps:
Dry pit submersible pumps are in the first instance made for applications where the pump unit is immersed in liquid. These submersible pumps are now utilized in dry well stations in which the wet well and the dry pump chamber are joined. Dry pit submersible pumps have changed the old centrifugal pumps.
12-Deep well pumps:
Deep well pumps can be utilized in well-water applications from 18′-27′ and more than 550′ in some conditions, making them a good option for wells that are narrow or deep. Just make sure to accept the proper pump size and the right two or three-wiring option for the application.
Deep well submersible pumps enjoy all of the advantages listed earlier, plus have the benefit of coming with a built-in check valve to ensure system pressure and backflow. Because these pumps are sealed and utilized underwater, they are virtually maintenance-free and are designed with corrosion-resistant materials.
13- Stainless steel pumps:
They are well enough coated with stainless steel, and thus, they have better acidic resistance. The full body of the pump can be immersed in the water while running.
14- Water cooler pumps:
Water cooler submersible pumps are typically employed in water supply for the factory, farmland, and residential areas. The motor of a water cooler submersible pump can be installed for working under the water. It can be filled with new water. These pumps are perfect in cases where high-quality water is utilized.
Application of submersible pumps
Submersible pumps are utilized in these factories: like drainage, firefighting, deep well drilling, irrigation, mine dewatering, artificial lifts, slurry pumping, sewage pumping, water wells, oil wells, seawater handling, and sewage treatment.
One of the main advantages of a submersible pump is that it can be directions below the bottom level without causing any access problems. They are thus fixed in a range of environments, such as:
- Where there is a specific space
- Agricultural programs

Operating capacity of submersible pumps
Submersible pumps come in a wide range of various sizes, depending on the particular application for which they are intended. Mini models can be utilized within homes or in light industrial settings and have a power consumption of between.
76kw and 2.2kw, flexible solids to a maximum of 65mm in diameter. For heavy-duty applications, such as in construction and factory applications, greater pumps are present and these can typically handle discard and solids up to 55mm.
How does submersible pumps work
A standard submersible pump works in a reasonably basic way. It starts by transforming rotary power into kinetic energy by using pressure power pulled in from the pump. As the water goes via the pump, it goes via the intake and is then pressed via the rotation of the impeller and into the diffuser. The water will then flow up to the outer layer where it can be used suitably.
Without dwelling excessively on the mechanical future, people interested in this pump should also keep a few different elements in mind. First of all, your pump must be plugged at all times to offer an advantage.
If it comes out of the water, it may end up overheating or undergoing other problems. These are quite minor and should not be too hard to stop if you take the time to follow the full operational options of this pump.
In this way, these pumps are reflected in multistage centrifugal pumps. Every operates in a vertical direction to produce a bigger amount of pumping power. The hydraulic motor in-house of the pump is regularly a closed-cycle pump, though it may also be an open cycle in some situations. The distinctions between the two aren’t that main to consider because both work in very parallel ways.
A submersible pump also has a multitude of various operational utilized to keep in mind. For instance, they can be utilized to drain fluids from the biggest field to keep their water levels accepted. They can also be utilized to shift sewage, manage pond filter processes, and even be utilized in oil wells.
The types that we offer are often utilized to pump water for wells in homes. This diverse range of methods makes them a beneficial tool to keep in mind for your assistance.
