Over the last month I have done three jobs on pumps. <ul type="square"> [*]Changed impeller on Volvo inboard,23Hrs use and signs of deterioration of rubber [*]Scrapped washing machine and salvaged pump (it might come in handy)Rigid plastic impeller goodness knows how many hours and gallons it has pumped over 13 years,no sign of damage or deterioration [*]Cleaned out pump in pond similar impeller to washing machine rigid plastic not touching casing and has pumped about 26280 Hrs no sign of deterioration or wear [/list]
Question is why cant we use rigid non sweeping impellers to push water round an engine,as it would appear to be an intrinsically more reliable way to move water about.Or is there already a better pump on the market I haven't stumbled across?
