If you are looking for a stainless steel dirty water pump suitable to pump for more than three consecutive hours, you can opt for the professional DAB FEKA VS 750 M-A.

Pros and cons

Stainless steel and cast iron
Very robust
Processes large solids
Switches on/off automatically
Drifting float, which may get caught behind things

The Extrema 400/11 Pro is the medium-range model in TIP's Extrema series. This partly stainless steel pump is highly suitable for processing dirty water, because it is able to process solids up to 40 mm, with a capacity of a maximum of 24,000 l/h. A true powerhouse and at a competitive price. The accompanying connecting pieces allow you to instantly connect your own hose or one from our product range to the pump.

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 40 cm
Switches off automatically at a water level of 25 cm
In manual mode (fastening/raising the float), this pump drains water to a level of 8 cm

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

Summary

The hose that can be used for this device is 2" in diameter
The pump is of German make and therefore robust and sustainable.
The pump's maximum submersion depth is 7 metres
Fitted with a vortex impeller for processing mud and solids (prevents clogging up)
Float for switching the pump on/off automatically. Can also be used manually
Thermal overload protection. The pump switches off when overheated

TIP

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.
