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.
This pump is capable of draining flat surfaces, but not every submersible pump is a puddle pump. If you are dealing with flooding and want to drain a space 'dry', you will need a puddle pump. Some models can even drain water to a level of 0 to 1 mm. This type of pump is often used for cellars, crawl spaces, or basements, and may be a perfect solution if groundwater rises and floods your house or garden. There are two ways to use a puddle pump. If it is fitted with a float, the pump will be able to drain to a level of about 4 cm. However, only in manual mode is the puddle pump able to 'drain dry', which means you need to switch the pump off yourself when it no longer processes water. This is important because the pump cools itself with the water it pumps. Therefore, to avoid the pump becoming damaged, it must be set to manual mode to drain surfaces 'dry'.
