Generator Guru Says:
The Impeller is the rotating part of the Pump that screws to the end of the Crankshaft accelerating the water outward from the centre of the Pump casing. When changing this part we would suggest changing the Mechanical Seal as wear to one will damage the other. This Seal sits behind the Impeller. It retains the water flowing through the Pump and maintains the pressure on the Impeller needed for the Pump to function efficiently.
Also be sure to inspect the Volute Casing for wear or cracking. These do not fail often, but can get broken by any parts which may have broken off the Impeller. A full failure of either part can result in the whole pump being smashed apart, as the engine turns the Pump at 3000 to 3600 rpm, and any metal breaking off will surely do massive damage to the Pump workings and casing.
We also highly recommend you replace the O-Ring Seals when reassembling the Pump. Old O-Ring seals can crack and pinch, causing loss in pressure and water leakage from the Pump casing.
