Spitwater Australia , manufacturers of high pressure water cleaners, exclusively use Interpump pumps in all their pressure cleaners. Spitwater has been using Interpump pumps ever since its establishment in 1983. And Interpump have been manufacturing high pressure plunger pumps for the last 30 years.
Interpump pumps are built to last and that is why they are an integral part of every Spitwater high pressure water cleaner. All these pumps have an aluminium die cast crankcase with an oil level window, oil drain plug for easy maintenance and a vented dipstick. The head of the pump is made from forged brass with dual symmetrical inlet and outlet ports. It is affixed with 8 fixing bolts to prevent possible damage caused by pressure peaks or freezing.
Inside, the pump has a forged crankshaft with heavy duty tapered roller bearings and oversize connecting rods in “white bronze”. The connecting rod pins are in special, hardened steel. The piston guides are made from stainless steel or nickel plated hardened steel. The piston guide bushing is Teflon, graphite or bronze. Piston bolts are stainless steel.
The business end of the pumps used on Spitwater high pressure water cleaners feature hardened ceramic plungers with a highly polished finish to ensure long seal life. Oil seals are made from special compound. Water seals are also made from special compound but are reinforced with natural cotton fibres. The exclusive pump pressure sealing system prevents leakage and is constantly lubricated.
