Pumps for draining flooded basements, pumping wastewater in households, lowering groundwater levels, emptying pools, excavations, shaft pits, etc. Submersible pumps are designed for pumping clean or only slightly contaminated non-aggressive water with solid mechanical impurities up to a diameter of max. 10-12mm. For more demanding applications, it is necessary to use sludge pumps.
Although the pump can draw from depths of several tens of meters, it is often more economically efficient to move the pump down to the water source. Submersible pumps best fulfill this role. Submersible pumps are elongated cylindrical devices that fit well into a well. The lower half consists of an enclosed motor connected to an above-ground power source. The actual pump in the second half of the unit consists of impellers separated by a diffuser, which drives water into pipes and the water distribution system. In modern installations, the submersible pump, even outside your house, is connected by a pipe running underground to the basement. This horizontal pipe connects the well pipe to an adapter. The function of the adapter is to allow access to the pump and pipes from above the well while pumping water into the water supply pipe.
Submersible pumps for boreholes are used in boreholes and drilled wells for drinking water. They excel with a specific shape that allows them to be lowered into the borehole, but also with high performance necessary for pumping from great depths. In the e-shop, we offer brands Grundfos and Wilo.
Submersible pumps are more efficient than jet pumps – they can pump larger amounts of water with the same motor size. Their problem is that in the event of any malfunction, they will need to be removed from the protective casing, which is a job more suited for a professional technician. However, submersible pumps are generally very reliable and can function for up to 25 years. Therefore, replacing the pump is not frequent. Submersible pumps can also be used in shallower depths, but be cautious of impurities, mud, etc., which can shorten the lifespan of your pump. For heavily contaminated environments, we recommend sludge pumps.
