The submersible pumps from

Everyone can suffer from it: flooding. It can happen in a basement under a home, but also in parking garages, distribution centers and shopping centers. Waterlogging can be caused by a lot of rainfall or flooding, but often the cause is rising groundwater or a broken pipe. Buildings that are equipped with a (parking) basement are especially sensitive because water always flows to the lowest point. Underground spaces are also often equipped with water pipes that can cause damage. You can use a submersible pump to quickly solve the problem of flooding.


What is a submersible pump?

Submersible pumps are capable of pumping large quantities of liquids. Characteristic is that the pump is always lower and the water is pumped up into the pump by means of the motor. This motor determines the pump capacity that is displayed in the number of liters per hour. The motor also determines the head. The head is the number of meters that the water can be pumped up. The special thing about the engine is that, unlike most engines, it is not air-cooled. The pump is always in the water, so air cooling is impossible. The cooling takes place through the pumped water. This is often also the reason that the pump must always be completely in the water before it can be started. The pump is therefore also equipped with a switch that is controlled by a float. This float indicates whether the pump is still completely in the water. When the pump becomes dry, it will emit a signal.


The benefits of submersible pumps

A big advantage of submersible pumps is that they are compact. For pumping water, whether it is from a residential cellar, a business premises or from a pond, the pump can simply be inserted and removed after draining. In the webshop of you will find a choice of various pumps, from light pumps to heavier pumps. Therefore, there is always a pump that meets your needs.

Another advantage is that these pumps and pump sumps can handle various types of water and liquids. Whether your home or business space is sufficient with normal water or sewage, most pumps can handle this. Pond water on the other hand contains a lot of sand, there are also special pumps for that. Or maybe you have a swimming pool and you want to pump out the chlorinated water. Most pumps and pumping stations can also handle liquids with chemicals.

If you require a fixed submersible pump to pump large quantities of liquid, then pumping pits made of concrete or plastic are a good solution. All the excess water or waste water is then pumped away from the fixed connection. But we also have a sufficient range of submersible pumps for lighter jobs. The most important thing to pay attention to is the capacity that a pump can handle and the head. Depending on the capacity of the pump, Diederen Afwateringstechniek always has a suitable pump for you. Still need advice on wells or other products? Then contact us.
