Submersible Pump: Types, Advantages & Disadvantages

Submersible Pump


A submersible pump is similar to a centrifugal pump with the same design as a diffuser or turbine pump; this help makes their shape compact.

These are usually of the multistage type of pump, so that the higher heads can developed.

The motors and pumps are compact units that are immersed in water during the operation; the unit is mounted in a vertical configuration.

There is a common shaft above the pump motor; the pump is connected to the mounting main by flanges and is suspended in it.

Between the pump and the motor, suction is provided; however, there is no suction problem as the pump is submerged.

A non-return valve is provided at the end of delivery; submersible motors are water-filled, water-lubricated squirrel cage type motors.

The axial thrust generated by the pump is absorbed by the thrust bearings at the bottom of the motor.


Sealing is provided to prevent well water from entering the motor and mixing with the water already filled inside.

Submersible pumps are efficient, maintenance-free, silent and long-lasting.

Types of Submersible Pump:

Bladder Submersible Pump:

The bladder pump is a non-contact, constructive displacement, pneumatically operated pump that uses compressed air.

The use of bladder pumps for groundwater sampling requires a controller that enables flow rates and cycles on the floor to be controlled.

Grinder Submersible Pump:

This is a wastewater drainage machine.

Once the wastewater contained in the tank reaches a selected stage, the pump will activate, grind the waste right into an effective resolution, and pump it into a central sewer system or septic tank.

Grinder pumps may be installed in basements or yards.


Well Submersible Pumps:

These are highly efficient devices that use centrifugal force to drain water from the underground reservoir in your home.

The type of well water pump you need depends on the depth of the well and how many horsepowers is needed to successfully pump the water.

Borehole Submersible Pumps:

These pumps are a type of submersible pump, which is used to regulate water or provides in various mining, farming, deep wells, rainwater retention and petroleum seize functions.

Fountain Submersible Pump:

Fountain pumps are designed to provide water movement and for equipment used for aesthetic functions and aeration in residential.

Utility Submersible Pumps:

Utility pumps are devices that are capable of pumping large amounts of fluid in a short period of time.

Typically, these devices are made of plastic, thermoplastic or stainless steel.

Submersible Pump Installation:

  1. Inspect the well, in search of indicators of exterior damage to the casing, test the depth and level of standing water.
  2. Inspect provided components.
  3. The motor is fitted to the pump.
  4. Split Drop Cable to Motor Cable to Supply Cable Split Kit.
  5. Lay the pump assembly next to a water well.
  6. Roll out the mounting main as well as the drop cable.
  7. Attach the drop cable 4-6 m (13.1–19.7 feet) in addition to the mounting main with 4-6 turns of grey duct tape.
  8. Check that the fittings are tight and that the cables are safe and sluggish to permit a stretch.
  9. If the load of the assembly can’t be safely managed, a curler made from the wheel of the automobile can be used.

Advantages of Submersible Pump:

1. Safe:

These pumps are a lot safer than different kinds of pumps as all probably harmful components of the pumps are stored underwater.

It is often coated and rarely consists of the potential for tampering the internal elements and valves.

2. Noise Level:

Submersible pumps rarely produce small quantities of noise because it’s submerged underwater.

Helps soften the sound caused by the pump.

Ordinary pumps are positioned exterior walls or sums, causing a considerable amount of noise.

3. Efficiency:

Compared to ordinary pumps, submersible pumps are extra environment friendly because it pumps liquid that’s closer to the pump; subsequently, it has fewer functions than regular pumps.

As these pumps are positioned inside the abstract, it could actually simply detect the water level.

Disadvantages of Submersible Pump:

1. These pumps have a short life because it collides together with your pond and sits.

2. It can also be tough to clean and keep as it’s sitting on the backside of the pond.

3. There is a chance that the pump might be starred and lose its seal, thus causing the liquid to enter the motor housing and trigger substantial harm to the unit.

Application of Submersible Pump:

  • Single-stage pumps are used for drainage, sewage pumping, industrial pumping, and slurry pumping.
  • They are also common with aquarium filters.
  • Multiple stage submersible pumps are usually discharged below the borehole and are used in water streams, water wells, and oil wells.
  • It should only be used for pumping clean and cold water that is non-corrosive and non-abrasive to the pump material.
  • It is used for irrigation in drinking water supply installations, pressure boosting air conditioning systems, industrial plants, cooling water systems, fountains, seawater desalination etc.

Frequently Asked Questions:

What type of pump is a submersible pump?

A submersible pump is a type of centrifugal pump that is completely submerged in liquid and pumps.

What is a submersible pump used for?

Submersible pumps are efficient for ejecting septic tanks.

Which submersible pump is best?

1. Crompton Greaves Self Priming Monoset Pump Mini Sapphire II- 0.5HP.
2. Kirloskar 40S Mini Water Pump 1Hp.
3. Kirloskar Jalraaj 0.5 HP Water Pump.

How does a submersible pump work?

A submersible pump pushes water on the surface by converting rotary energy into kinetic energy into pressure energy.


The submersible pump was powered by a method of power or generator of its personal energy supply.

This decreased fuel costs and noise generated by works

This was the identical sample for each the principle energy model and the generator-powered model, which was largely sound-proof.
