Submersible pumps are used for pumping drinking and utility water from boreholes, wells, and collection tanks. They are fully submerged in water, from where they push the water column to the points of use, allowing them to pump water from depths of up to 150 meters while maintaining the required pressure in the system.
The specific shape and small diameter of the pump (from 74 mm) allow installation even in narrow boreholes. The cooling of the submersible pump is ensured by the flow of surrounding water, which gives borehole submersible pumps high performance. The same effect can be achieved with a cooling jacket. If necessary, the borehole pump can also be used to pump other liquids without mechanical impurities. Submersible pumps allow the pumping of clean water with an acceptable amount of sandy material or other abrasive substances in the range of 50 to 150 g/m3.
You can choose from a wide range of borehole pumps. We recommend purchasing a complete set, which includes everything you need (including a pressure tank, built-in electronic control unit for maintaining constant pressure, etc.). Another option is to purchase individual components separately.
A well-chosen submersible pump will ensure a constant supply of water from your own source for many years. Additionally, you can easily extend its lifespan with proper care.

Submersible borehole pumps are used for pumping groundwater both for domestic use and for the gradual removal of excess groundwater reserves. If necessary, the borehole pump can also be used for pumping other liquids without mechanical impurities. If there is a large amount of sandy material and other abrasive substances in the borehole, it is necessary to clean the water borehole first, for example with a submersible vibration pump.
Submersible pumps are fully submerged in water (below the dynamic water level of the borehole), from where they push the water column up to the collection points, allowing them to pump water from depths of up to 150 meters. This distance is called the head (denoted as H) and, together with the flow rate (the volume of water pumped, denoted as Q), are important parameters for selecting a submersible water pump. Both values are provided by the manufacturer and differ for each type of pump, so it is important to choose a submersible water pump specifically for the particular borehole conditions.
Submersible borehole pumps are designed for long-term submersion and are manufactured from a diameter of 74 mm, making them suitable for use even in very narrow boreholes. However, it is necessary to leave sufficient space between the pump casing and the borehole wall. The flow of surrounding water provides cooling for the pump, which allows the deep well pump to have high performance and provide a constant water supply. If the necessary cooling of the borehole pump cannot be ensured by water flow, the same effect can be achieved by installing a cooling jacket.
When selecting a submersible borehole pump, it is important to consider the yield of the borehole (otherwise, dry running of the pump could occur) and other factors that affect the lifespan of the pump. Submersible pumps with a frequency converter can adjust the output to achieve a constant water pressure even in the event of fluctuations in the electrical grid voltage.
An advantage of the submersible pump is its easy installation, which is possible both in a vertical and horizontal position (a stainless steel cable is used for suspending the pump in the borehole). The pump includes a connection cable, which can be extended if needed for deeper boreholes.
Before purchasing a submersible borehole pump, don't forget to prepare your borehole for water pumping, and then simply choose from a wide range of submersible pumps from leading manufacturers Grundfos and Wilo.
