The right pump for a construction site is the one matched to the water, the lift and the power on site, not the one with the biggest flow figure. For most groundworks that means a submersible dewatering pump that tolerates grit and runs hard, sized to keep the excavation dry as fast as the water arrives.
We supply site and civils contractors, groundworkers, self-builders and plant hire, with pumps the hire fleets trust, in 110V and 230V, and engine-driven where there is no power. All held in UK stock for next working day.
General dewatering of digs, trenches, foundations and manholes. Submersible contractor pumps that run continuously and handle grit and small stones.
Featured: Tsurumi LB480, LB800 and LB1500; EVAK Drainox 400/750 and Drainox 1500; Tsurumi HS2.4S; Tsurumi OM5 and HSD2.55S. See site drainage and dewatering pumps.
Where fines settle and block a standard intake, you need an agitator or a pump built for abrasive water.
Featured: EVAK Trenchman 400 (built-in agitator, 15 mm passage); BBC Semisom 262 and 635; Arven Regal 304 stainless; Arven Mizar VOX. A matched Silty Trench Dewatering Kit is on the way.
Site puddle and flood clearance to a few millimetres off a slab or in a shored pit.
Featured: Stream SPK530; Stream SPK450A (110V); EGO 500 GI and GI LS; Tsurumi LSC2.75S; EVAK Residox 750. See puddle pumps.
Petrol and diesel pumps that sit on the bank and draw through a suction hose.
Featured: Honda WB20, WB30 and WX10; Tsurumi TE, TEF/TEW, TDS and TD petrol; DryMax diesel. See engine-driven pumps.
Transformer-fed pumps for 110V sites, same kit otherwise.
Featured: Stream SPK450A; Tsurumi LB480 and 50PNI2 in 110V. See 110V pumps.
Matched site kits, with the pump, hose, strainer and fittings sorted for the job, are being built for construction: a Contractor Dewatering Kit (Tsurumi LB480), a Silty Trench Kit (EVAK Trenchman) and a High-Flow Dewatering Kit (APP HD-15). In the meantime, see the pump kits range.
We are engineer-led and hold UK stock for next-day. We supply hire-grade brands such as Tsurumi, carry 110V and 230V across the contractor range, and keep spares. If the lift, distance or ground conditions make the job harder than a catalogue pick, our engineering review service covers the projects that need sizing and calculations.
Many of these are FPS Engineered™ combinations, specified and matched by our team. Learn more about FPS Engineered™.
A submersible contractor pump sized to the inflow, not the headline maximum, and one that tolerates grit. If the water is silty, choose a pump with an agitator such as the EVAK Trenchman. See site drainage and dewatering pumps.
Use an agitator pump that keeps fines in suspension, such as the EVAK Trenchman, or an abrasion-resistant pump built for gritty water. A standard clean-water intake will clog as silt settles.
110V for transformer-fed sites, 230V where there is building mains. Many contractor pumps are offered in either voltage with identical performance. See 110V pumps.
An engine-driven pump that sits on the bank and draws through a suction hose, sized by its outlet. See engine-driven pumps.
Match the pump to the rate the water arrives, not the biggest flow figure on the box. Vertical lift and hose length reduce the delivered flow, so allow headroom or check the duty.
Buy where a pump earns its keep across enough jobs; hire for one-off peaks. We supply spares so a bought pump keeps working.
