Capable of shifting a huge 4200-litres of water every hour, this powerful 400w electric pump from German manufacturer Einhell is ideal for the draining of hot tubs, swimming pools, cisterns, water butts, & similar tanks containing large volumes of clean water (it's highly recommended as a way to water plants etc directly from a rain-barrel). The Einhell BG-SP 400 RB couldn't be easier to operate: just connect-up the pressure hose; place the unit into the water to be pumped-out; switch on; & watch as the tank is swiftly drained. Einhell's provision of an infinitely variable float-switch means you can choose the water level at which the pump kicks in. Thanks to its integrated filtration system, the Einhell BG-SP 400 RB Rain-Barrel Pump will cope with dirt & debris particles up to 3mm in diameter. A carry handle means you'll find it easy to move the pump with from place to place; while the provision of a universal connector works to enhance flexibility-of-use. The Einhell BG-SP 400 RB has a stainless-steel drive-shaft, so it will cope easily with regular periods of continuous operation. Durability is further enhanced by its rust- & impact-resistant plastic housing.
