Types of water this pump can handle
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.
Dry-running protection
The name says it all: this pump is protected from running dry. Most pumps cannot, if at all, operate dry for long, which usually ends in the pump immediately burning out and/or seizing. For example, this could happen if the source has run dry and the pump can no longer draw water from it. Garden and booster pumps are particularly sensitive to running dry. Some borehole pumps and somewhat more advanced garden pumps are already equipped with built-in dry-running protection. Others can be easily fitted with a dry-running protection system: for example, with a separate one or with the DAB Control-D. This definitely guarantees that the garden or booster pump will not run dry.
Grundfos
Grundfos is one of the largest pump manufacturers in the world. They have managed to obtain a substantial share in the industrial market, and have achieved this by supplying the highest quality products over a period of several decades. As a result, Grundfos pumps are currently used in many installations and situations. Not surprisingly, your central heating system may also be fitted with a Grundfos circulation pump. Grundfos was originally a Danish company but it is now represented in many countries all over the world. In addition to manufacturing central heating pumps and targeting the industrial market, Grundfos also sells several garden and booster pumps, and has a line of very robust, high-quality submersible pumps.
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.
Quiet
This pump is labelled as being 'quiet'. Of course, like any electric appliance, a pump can be heard, but special attention has been given to its noise level. Thanks to its ultra-low noise level, the pump is highly suitable to be placed indoors, without being disturbing. The perception of noise is subjective, of course, but no other pumps are quieter than these.
