Powerful Makita 400W submersible pump for dirty water. 140L/min flow, 5m head, handles solids up to 35mm. Automatic float switch.
The Makita 400W Submersible Dirty Water Pump is a robust and reliable solution for a wide range of demanding drainage and water transfer tasks. Engineered for efficiency and durability, its 400W motor provides substantial pumping power, capable of handling dirty water with solids up to 35mm in diameter, making it ideal for construction sites, flooded basements, garden ponds, and agricultural use.
This pump features a high flow rate of up to 140 litres per minute, allowing for rapid water removal. It offers a maximum head (vertical lift) of 5 metres and can be submerged to a depth of 5 metres, providing versatile placement options. A key feature is the automatic shut-off mechanism controlled by an adjustable float lever, which prevents dry running and protects the pump from damage when the water level drops too low.
Constructed for tough conditions, the pump is suitable for draining basins containing muddy water, emptying wells and storage tanks, and lifting water for irrigation purposes. Its design allows it to handle clean water with particles up to 5mm and has a minimum suction level of just 40mm, enabling it to pump water down to very low levels.
For user convenience, it is supplied with a UK mains plug (Type G), ready for immediate use. The compact and submersible design makes it easy to deploy directly into the water source without the need for complex priming procedures.
