Product description

Within this series, DAB provides two types of pumps for reusing rainwater. Depending on the required pressure / water pressure, one may choose between the:

In addition, there is also the option of choosing a more professional series, the so-called Aquaprof Top series:

The main difference between the Basic and Top line is that the Basic line measures the rainwater level using a float switch and therefore has no rainwater level display features. The Top line on the other hand has a probe and can therefore display the rainwater level on a screen.

The DAB Aquaprof Top 40/50 is an advanced system for reusing rainwater in the home and companies. This saves you on costs and water consumption, allowing you to recoup your investment within a relatively short time. One of the main benefits of this system is that it directly switches to the regular water network once the rainwater is depleted. In other words: guaranteed water supply.

Water supply guaranteed

In some situations, it will be essential that water is always available. This may not always apply to irrigation, but it is definitely crucial when it involves supplying water for toilets, washing machines, or other appliances. In these situations, this pump is extremely suitable. It may be useful if you are not 100% certain whether the source contains sufficient water. The pump can offer a solution in the form of an automatic switch, which ensures water is always drawn, but instantly switches to the water mains system when the source has run dry.

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.


DAB is one of the best-selling brands of water pumps for consumers as well as for professionals. These pumps adhere to a very high standard of quality, with each pump being tested manually by a staff member before it is put on the market. This is the only way DAB can guarantee that you obtain the absolute best. They have a solution regarding almost any situation, whether it involves an industrial application or simply spraying a garden. DAB's professional quality is also reflected in its consumer line. The DAB pumps we replace for people are usually over ten years old.

Automatic activation / deactivation

This pump switches on or off automatically if you open or close a water point that is connected to the pump. In many cases, this feature is a considerable advantage: for example, when irrigating a garden with a hand-held sprayer, or supplying a toilet or washing machine with rainwater. It is also useful if you want to increase the water pressure in your home. Unlike standard garden water pumps, water pressure pumps - because of the difference in pressure - 'notice' when one or more water points are opened or closed. This is how the pump knows that it needs to start or stop. Standard water pressure pumps (which are mounted to a tank) are equipped with a mechanical switch, and the more advanced ones have electronic switches. Both systems have advantages and disadvantages. The mechanical switch is reliable but can either not be set or it is difficult to do so, while the electronic version can be set but is dependent on electricity.
