Reduce Mean Time to Repair in your High Head Pumps

These pumps usually sit in cramped or remote locations. As a result, there are few opportunities for visual inspections that could prevent early failure. On top of the adverse conditions, the design of the pump is also relevant. They need to accomplish maximum flow and minimal leakage. However, a robust casing may difficult the access to certain components, affecting maintenance efficiency.

There is a new series of high head pumps with an improved design that reduces mean time to repair (MTTR) and maintenance costs. A new hinge kit solved the issue of ready access to the hydraulics. The machine has a 'swing door' that allows quick access to the inside. These high head pumps also have a single bolt to remove the impeller.

The new design includes a semi-cartridge seal that can be changed from the front. This feature allows changeout without dismantling the pump and reduces mean time to repair. And an integral seal oil bath prevents damage if the pump runs dry. Besides, the new breed of high performance pumps has a closer impeller with deflector vanes. It keeps the seal clean and improves shaft balance on the shaft and impeller.

In conclusion, through a number of design innovations, traditional issues regarding maintenance have been addressed. If all these features meet in a single machine, mean time to repair (MTTR) improves by up to 30%.
