Submersible pump sucks up the stuff
AUTO on/off operation, controlled by a float switch, is incorporated on a portable 25mm (1in) submersible pump.
Clarke Power Products claims its Hippo 2A electric pump is capable of pumping up to 85 litres/min (18gal/min), and lifting the liquid to within 3mm (0.1in) of the base of whatever container it is housed in.
Powered by a 240V electric motor, the Hippo pump is supplied with auto-thermal overload, 10m (33ft) of water-proof cable and an anti-silt filter base. Price is £72 (0181-986 8231).
