Pump Reconditioning Process and How It Can Save You Money

September 25, 2018

Pumps are reliable devices. Even when they're in service, day-after-day, for weeks and months on end, they function reliably. By design, it's a set of stringently enforced engineering values and production standards that make sure they're equipped with this long lifespan. Even when those features wane, there's a pump reconditioning service to provide a lifespan reclaiming support service.

Maintenance Estranged Pumps

In some hypothetical factory, a place that ignores its pumps and fittings, equipment is aging prematurely. In a centrifugal pump, its volute is cracked. Head pressure is fluctuating, and the leaking mess is creating a messy puddle on the factory floor. Elsewhere, the bearings on a rotating assembly have seized. The circuit breakers are tripping, the electric cables are overheating, and the quarterly power bill is spiking high. What do the equipment owners do to fix these issues? They use a patch-it-and-fix-it mindset. Replacing a bearing, maybe adding a few litres of lubricant, or by replacing a burnt out motor, they keep the facility ticking over. Avoiding this debacle, pump reconditioning services overhaul or "recondition" aging parts.

Reconditioning Services Save The Day

As mentioned in past posts, reconditioning work acts like a full-on equipment face-lift. For those damaged motors, their bearings are replaced. Their electrical windings are pulled, then a rewinding service is applied. It's not a cheap process, but it's more cost-effective than the alternative. Reconditioned pumps return to their connections, plinths and bays in peak operational condition once more, with freshly minted windings, newly replaced and lubricated bearings, and more. Progressive cavity pumps, well, these screw-like constructs have obviously been designed to rival their rotary/volute-equipped cousins, especially when it comes to reconditioning work.

Helical Pump Reconditioning

Just to review the matter, the screw section inside a progressive cavity pump will age over time. Abrasive mediums cause the alloy strengthened surfaces to pit and score. The scratches are repairable, at least at first, by opting for a resurfacing procedure, one that double-coats the shaft in an abrasion-resistant finish. However, left unresolved, the cost-effectiveness issue goes out the window, for that damage accumulates and deepens. Suffering from its subtractive wounds, it's much harder to replace a heavily abraded rotor. There are welding techniques and several other additive repair techniques, of course, but the results of those operations can vary.

Cost effective repair strategies are, more often than not, regarded as time-sensitive solutions. Energy losses accumulate when bearings rust and squeal. Motor windings, perhaps suffering an electrical continuity issue in one phase of their windings, burn out completely when the matter isn't properly addressed. Meanwhile, on helical pumps, fluid pocket integrity is destroyed by geometrically irregular rotors, at least until a shaft reconditioning service rescues those prematurely failing rotors and their elastomeric stators.
