The MD80 Drainjetter has a number of good advantaged, it is brilliant for drains up to 300 metres long and 250mm diameter. The high pressure pump has an out-put of 80bar and a working pressure of+/- 15bar and 120l/m flow at the nozzle head. The high speed water coming out of the adjustable nozzle through the rear facing holes drives the hose up the drainpipe. At the same time this back flow of high speed water flushes the sediment from the drain.
The hose has been specially developed and manufactured for this machine with a pressure rating of 80bar lengths of 100, 150, 200 and 300 metres that can be supplied on the reel. The retrieval of the hose from the drain is a VEE belt system driven off the water pump.
