What do you need to be aware of when you buy a submersible pump?

The name says it all: a submersible pump is immersed in a liquid, and it pumps away water that is of an undesirable quality.

There are different types of water pumps:

  1. submersible puddle pumps

  2. high-pressure submersible pumps
  3. submersible pumps fitted with a float, a built-in float, or a float switch
  4. submersible pumps for clean water, for dirty water/wastewater, for water with solid particles.

If you are looking for a submersible pump, we will be happy to help you find the appropriate model. Please refer to the pump configurator on our homepage. If you specify your wishes and requirements, the configurator will work out which pump best fits your situation, and you will be assured that you are choosing the right one.

Submersible puddle pumps

A puddle pump has an inlet at the bottom to draw in water, and can be ideal if the water level is not too high. Its inlet is situated only a few millimetres away from the surface so that the water can be drained to a very low level. Check here our submersible puddle pumps.

High-pressure submersible pump

This type of submersible pump has more power than a regular model, and can be used as a garden pump or to connect a high-pressure cleaner.


In principle, practically all submersible pumps are fitted with a float that automatically activates the pump if it is located in water. Some models have either a built-in or an external float, and others also have a float switch, which gives the option of letting the pump switch on/off automatically or not. 

Clean water, dirty water/wastewater, or water with solid particles

When you buy a pump, check the type of water it is able to process: for instance, only clean water or dirty water. Dirty water is cloudy and contains sand. Draining your cellar can usually be done with a clean-water pump, but the water in a septic tank is considered to be highly contaminated. Solid particles are referred to as anything larger than a grain of sand. Please also check the pump's specifications, which specify the size in millimetres of the solid particles the pump is able to process.

Other things you need to take into account when buying a pump include:

  1. The space where the pump with a float needs to be situated;
  2. Whether there are possibilities for connecting it;
  3. The capacity required, or rather, the size of the tank;
  4. Where you want the water to come from and to which location you want it to drain. This refers to delivery head and suction depth.
