WATER PUMP REPAIR KIT

770 119 00 WATER PUMP REPAIR KIT is the core of your dust suppression and flushing system. It pushes water from the tank, through the lines, and right down to the bit face. Without it, you're not just dealing with a dust storm; you're looking at premature bit wear and potential overheating of your down-the-hole hammer or drill string components. It’s all about maintaining that critical flow to clear cuttings and keep temperatures in check.

You’ll start noticing a few things when this pump begins to give up the ghost. The most obvious is usually a drop in water pressure at the bit, which means more dust billowing out of the hole. Sometimes you’ll hear it too – a change in the pump's normal hum, maybe a grinding noise if the bearings are going, or even just a general sluggishness in the water flow. If you're running a DTH hammer, that lack of cooling water can really shorten its life, not to mention the mess and visibility issues from all the dust.

When you're swapping one of these out, make sure you properly flush the system beforehand. Debris in the lines is a common killer for new pumps. Also, don't forget to check all your hose clamps and connections upstream and downstream. A small air leak on the suction side can cause cavitation and ruin a fresh pump quicker than you'd think. It’s not just about bolting on the new one; it's about making sure the whole circuit is clean and sealed.
