Product description

This is a powerful submersible dirty water pump that can be used to process large amounts of dirty water/wastewater with solids up to 30 mm.

Water level

This pump is fitted with a float switch, which means that it switches on/off automatically based on the water level.

  • Switches on automatically at a water level of 39 cm
  • Switches off automatically at a water level of 20 cm
  • In manual mode (fastening/raising the float), this pump drains water to a level of 5 cm.

If you are looking for a pump that leaves less water/switches on automatically sooner, you can opt for a submersible puddle pump.


  • The hose that can be used for this device is 1.5" in diameter
  • The pump is produced in Germany and is therefore robust and sustainable
  • The pump's maximum submersion depth is 5 metres
  • Fitted with a vortex impeller for processing mud and dirt
  • Float for switching the pump on/off automatically; can also be used manually
  • Thermal overload protection; the pump switches off when overheated

TIP is a German manufacturer, specialising in water pumps for consumers. They have a very interesting range of mainly Inox or stainless steel pumps, fully tailored to the consumer market. Their products range from high-capacity submersible pumps at highly competitive prices to good stainless steel borehole pumps for situations in which water needs to be pumped up from a level deeper than eight metres. Furthermore, TIP is very good at accommodating the consumer. For example, some pumps come with a kit designed to start up immediately, while others are fitted with handy features, such as a top outlet or a baseplate.

Stainless steel / Inox

In some situations, stainless steel, which is also called Inox steel, can be very handy, and is prescribed in particular with regard to drinking water. Drinking water must remain pure and may not contain corrosive elements, which is the reason that stainless steel is used. Furthermore, a stainless steel pump is also resistant to lime, which tends to stick to surfaces, but is not able to do so with smooth, stainless steel surfaces. Cast iron is usually the counterpart of stainless steel, but these pumps are prone to corroding and are therefore used mainly for irrigation. A final advantage of stainless steel is that it is lighter than cast iron and is therefore easier to move.

Float for automatic activation / deactivation

This submersible pump is fitted with a float, which ensures that the pump is switched on and off automatically. Each pump has its own variables relating to the level at which the pump switches on or off. Robust wastewater pumps usually have a high level of activation and deactivation. They will start operating relatively late and stop relatively soon, unlike puddle pumps, which switch on sooner and switch off later. Check the pump's specifications for these variables. There are three types of floats: a floating one, which is attached to a cable; a float arm; and an integrated float. The first type needs more space because it may float in any direction, while the float arm needs less space, as it only moves up and down, and generally has higher operational reliability. Finally, there is the internal float, which is integrated in the pump and therefore needs the least space. We see these internal floats mainly in puddle pumps, because they need to operate in small spaces.

Frequently asked questions

How does a float work and what can I do with it?
A float ensures that your pump switches on and off automatically at a certain water level. This is very practical if you want to use the pump in frequently flooded spaces, because with a float the pump does not need to be switched on and off each time the space is flooded. If you want to use the pump manually, the float should be raised or fastened with a piece of rope or tape.

At what water level does the pump switch on/off automatically when the float is used?
This submersible pump switches on automatically at a water level of 390 mm and off at a water level of 200 mm. To ensure that the entire space does not maintain a water level of 200 mm after the pump automatically switches off, the device is often placed in a sump pit. This ensures that the pump is situated lower in the space, so that the device continues pumping until a water level of 200 mm has been reached in the sump pit. In this way, the rest of the space is pumped practically dry, with only some water left in the pit.

In what situations can I use this pump?
This pump is suitable in the following situations:

  • for draining a cellar and/or crawl space
  • in a permanent setup, for example, to automatically drain a cellar/crawl space once the water level has been reached
  • for draining a basin
  • for draining a swimming pool
  • for draining a pond or ditch
  • for draining a construction pit and other wastewater sources.

What is the difference between the Maxima 18000, the DAB NOVA 300 M-A, and the DAB FEKA 600 M-A?

  • The Maxima 18000 is a starter model for pumping dirty water that can be used in almost any situation involving wastewater. This pump is also available with a higher pump capacity: namely, the Maxima 24000, which can process 24,000 litres per hour.
  • The DAB NOVA 300 M-A is a dirty water pump suitable for slightly smaller solids (up to 10 mm). As a result, this pump can be particularly useful for flooded cellars/crawl spaces that contain just a little more sand or gravel.
  • Of all four models, the DAB FEKA 600 M-A is the most advanced and robust dirty water pump. Owing to its robustness and internal technology, this submersible pump can be used, for example, as a faecal pump in a manure pit or sewer system.

Can this pump be set up in small spaces?
This pump requires a space with a minimum diameter of 25 centimetres and can therefore be set up practically anywhere.

Is the pump supplied ready for use?
Yes, this pump is supplied with every component needed for immediate use. You only need to attach a discharge hose to transport the drained water to a particular location. The discharge hose in our product range is suitable for this pump.
