A borehole pump lifts water from deep underground sources: drilled boreholes, wells, reservoirs and storage tanks. The pump and its sealed motor sit fully submerged below the water level and push water to the surface, which is why borehole pumps handle depths that no surface-mounted pump can reach.
We supply submersible borehole pumps for private water supply, agriculture, irrigation and industrial abstraction across the UK, with ranges from Calpeda, Ebara, Lowara, Pentair and Pentax. Browse the ranges below, or send us your borehole test data and we will size the pump for you: call +44 1332 913500.
A borehole pump is a slim, vertical multistage pump built to fit inside a drilled borehole, typically 4 inch (around 100 mm) or 6 inch (around 150 mm) in diameter. The pump end is a stack of impellers and diffusers: each stage adds pressure, so deeper boreholes and higher pressures simply need more stages. Bolted below it is a sealed submersible motor, powered through a submersible cable and cooled by the water flowing past it.
Because the whole unit works below the water level, it pushes water up rather than trying to suck it up. That removes the suction lift limit, priming problems and cavitation risk that rule out surface pumps on deep sources.
The pump hangs in the borehole on a riser pipe, with a check valve above it to stop water draining back when it switches off. At the surface, a control box handles starting, overload protection and dry-run protection, and on pressurised supplies the pump usually feeds a pressure vessel so it is not cycling on every tap opening. Dry-run protection matters: the motor relies on surrounding water for cooling, so every installation should have a level probe, pressure switch or current monitor fitted.
Sizing starts with the borehole itself, not the pump. The inputs that matter are the borehole diameter, its tested yield, the static and pumping water levels, the flow rate you need and the total head (lift plus friction plus delivery pressure). An oversized pump draws the borehole down faster than it recharges and ends up running dry; an undersized one never delivers the flow. Send us your borehole test data and application details, and we will specify correctly, including cable sizing and control gear.
Standard construction suits clean groundwater, with stainless steel specified for aggressive, high-chloride or potable water and specialist options for sandy or contaminated sources. We stock submersible borehole pumps from Calpeda, Ebara, Lowara, Pentair and Pentax, and as independent specifiers, we match the pump to the borehole rather than defaulting to one brand. Borehole pumps are close cousins of our multistage pumps, and for surface boosting from a storage tank, see our booster sets.
Planning a new borehole installation or replacing an existing pump? As experienced borehole pumps suppliers, we can help you choose the right solution, call us on +44 1332 913500 with your borehole details and application.
It depends on your borehole diameter and yield, the flow you need and the total head. 4 inch pumps cover most domestic and light agricultural duties; 6 inch and larger suit irrigation, industrial and municipal flows. Send us your borehole test data and we will size it for you.
Submersible borehole pumps can lift from depths of several hundred metres; the practical limit is usually set by the number of stages, motor rating and cable sizing rather than the borehole depth itself. Tell us your water levels and we will confirm what your duty needs.
Yes, but private supplies used for drinking or cooking fall under the Private Water Supplies Regulations, so the water must be tested and treated appropriately. On potable duties we can specify pumps with WRAS-approved materials.
No. The submerged motor is cooled by the water around it, so dry running damages it quickly. Every installation should include dry-run protection, typically a level probe, pressure switch or current monitor, which we supply alongside the pump.
Cost is driven by borehole diameter, the head and flow required, construction material and the control gear needed. Rather than quote a generic figure, send us your borehole details and we will price the right pump for the duty: request a quote.
