The Draper SWP330/1100 is a 1100W submersible dirty water pump designed to rapidly remove muddy, debris-laden water from flooded basements, construction sites, and other demanding environments. Unlike standard clean water pumps, this submersible pump is built to handle thick, contaminated water containing solids up to 35mm in diameter — particles that would quickly clog or damage a conventional pump. With a maximum output of 330 litres per minute and a maximum head height of 9 metres, it delivers the performance needed for serious site drainage and flood clearance. The automatic float switch monitors water levels continuously, switching the motor on and off as required without the need for manual intervention. This makes the pump well suited to unattended operation in basements, excavations, or anywhere water levels fluctuate. Thermal overload protection provides an additional layer of safety, cutting power to the motor automatically should it overheat. An automatic air bleed valve prevents air locks from disrupting pump performance, while the 10-metre power cable provides useful reach from a power source. The pump accepts hose adaptors in 25mm, 32mm, and 40mm diameters to suit common site hose sizes. At 6.46kg with an integrated carry handle, it remains easy to transport and position on site.
