What is a submersible pump?

As the name suggests a submersible pump is a pump that can be submerged under water.  Sometimes called a bell pump,  these pumps are located within the reservoir of water that needs pumping out. The motor is hermetically sealed and close-coupled to the body of the pump. With the components hermetically sealed they cannot be damaged by the liquid they are intended to pump.

Submersible pumps are suitable for draining waste and clean water or sewage containing soft solids.

How do submersible pumps work?

A submersible pump operates by pushing, as opposed to drawing, liquid during the pumping process. Designed to pump excess water from flooded spaces, these robust pumps can continue working while fully submerged underwater. Pushing water requires less energy, than drawing water – making the submersible pump a popular choice for applications that require continuous operation.

Submersible pumps need to be submerged to operate, this allows the motorized impeller to draw water into the pump. The submersible pump uses direct pressure through the hose to remove the fluid. This allows the pump to cover a greater distance than a suction pump.

The submersible pump is a centrifugal pump, its impellers are designed to transfer rotational energy from one or more driven rotors This movement gives water both kinetic and pressure energy.  When the water passes each impeller, the pressure gain is multiplied.

Submersible pumps use a float switch. This is used to monitor water levels and control the motor. The float switch will automatically turn off the motor when the water reaches a pre-determined level. The float switch will reactivate the motor when required. Submersible pumps operate independently of user input and are fitted with an alarm to alert the occupier if there is a fault outside of scheduled maintenance.

Applications for submersible pumps

Submersible pumps are very reliable. Due to the fact they are continuously submerged, and therefore more difficult to access and maintain,  submersible pumps are designed to be robust with a long life cycle.

Submersible pumps are generally made with iron castings and protected against corrosion with coated epoxy. There are many applications for submersible pumps, including:

  • Emptying Ponds
  • Dredging
  • Water Wells
  • Bore Holes
  • Mines
  • Marine Applications
  • Flood Water Removal
  • Sewage Treatment
  • Sump Pumping
  • Powering Water Features
  • Draining Building Sites

Advantages of submersible pumps

  • Priming: Submersible pumps are self-priming because they operate below the surface of the fluid to be pumped. There is no requirement to be primed.
  • Cavitation: Submersible pumps are not prone to cavitation.
  • Efficiency: A submersible pump has the head pressure of the liquid on the suction end to help it operate. This means it does not require as much energy to draw in the liquid that requires pumping, resulting in a more efficient process.
  • Noise: Because they are fully submerged, these pumps are generally quieter in operation.


What to consider when buying a submersible pump

  • Type Of Water – Dirty Or clean?
  • Discharge Height
  • Discharge Rate
  • Power Back Up
  • Suction Depth
  • Outlet Size
  • Bore-Well Size
