This pond pump from PondXpert boasts the lowest running costs we have ever seen from a filter pump! Despite the generous flow rate of 5000lph the engineers at PondXpert have managed to develop an efficient motor to create this flow requiring just 26 watts of power! The pond pump comes complete with a 20-40mm hosetail so will accept 20-40mm hose (3/4\" to 11/2\"). If your pond water runs too low the pump will automatically detect this and switch itself off to avoid damage. This pond pump is designed to run continuously \'24/7\' servicing a pond filter system or waterfall. * Saving based on higher wattage of typical specification pumps on the market. based on pump running 24/7 for 365 days per year.
