Part number- PPM300HP65

The engineers at Banjo have designed the poly pumps to protect the engine seal in the event of pump seal failure. The 3" Honda pump is separated from the engine by 1/2” and a special slinger/engine seal that protects the engine from any corrosive fluids when installed. This new slinger design is the best in the poly pump industry at protecting your engine. For additional seal protection, small vanes are moulded into the backside of the impeller. During operation, these vanes pump out a major portion of the liquid from the seal area which reduces pressure. The internal operating pressure of the pump is approximately 50 PSI with the seal area operating at only 5 PSI. This leaves enough liquid in the seal area to lubricate and cool.
