Rebuild Your Pump

Believe it or not, pump repair can be a blessing in disguise. The pump breakdown allowed our engineer's a chance to examine and re-engineer it, so it is better than new, with improved operating efficiencies and the chance to lead a longer, and more productive life.

But why wait for a costly breakdown to occur? Let our experts check out your pumping equipment, NO MATTER WHAT MAKE OR MODEL. We will get it in peak shape and then set up a preventative maintenance schedule to keep it operating at it's best.

Contact one of our QRC operations to arrange for them to visit your facility and give your pumping equipment a whole new lease on life.

Trends towards pump repair:
» When a pump breaks down or becomes worn, customers have two choices. They can replace it or they can have it repaired.

» Today the cost savings of having it repaired are 20-80%

» In many cases the quality of the repaired part/pump will exceed the quality of the original. Because our engineers have the benefit to see how the existing pump performed-or failed to perform- in a specific application. Based on the condition of the pump and a history of it's performance, our pump engineers can rework the design to prevent a particular type of wear or corrosion or other problem. Our technical specialists are in the best position possible to choose the appropriate metals or exotic alloys for the application.

» Rebuilding pumps creates an opportunity for design modifications that can improve strength or efficiency.

» An increase in the separation between shaft critical speed and actual pump speed can reduce a pump's vibration and sensitivity to imbalance.

» Material thickness can be adjusted to ensure resistance to cracking, if cracking has been a problem.

» There are at least three main causes of damage to pumps:
      » Wear- Internal Recirculation
      » Corrosion
      » Running outside the desired pump operating
         range-Cavitation-Surging

» Wear- The pump technical specialist analyzes the failure circumstances to determine what variables are responsible. In some cases, just the shaft and frame will be preserved and the rest of the pump is rebuilt. Wear also occurs because the pump components are not hard enough to resist erosion from dirty water, solids and other abrasives. Dozens of new materials and coatings are available in the marketplace today. This is good time to pool the resources of the plant engineer, the pump specialists and the material/coating specialists to determine the optimum alloy or coating.

» Corrosion- The pump specialist begins by identifying the variables responsible for the corrosion condition. Analysis of the pumpage with respect to operating conditions, temperature, PH and other factors will provide the useful data to make the optimum material selection.

» Pump Operating Range- Each pump has an optimum operating range to provide both good hydraulic and mechanical performance. Operating outside this range will result in one or many of the following: cavitation, surging, high vibrations, high temperature rise, high thrust values, accelerated internal recirculation, reduced mechanical seal life and bearing life.

Conclusion:

The value of analyzing the precise cause of a pump's degradation whether it be wear, corrosion or off pump desired operating range, appears over the long term in substantial capital savings. To replace a pump that performed below par with another just like it, hoping for another short period of just-adequate performance, does not make good sense. The sensible approach- and appropriate approach from an engineering/reliability standpoint- is to assess the cause of the pump's degeneration, and use this information to repair or replace the pump with an improved model. In many cases, repair proves the more economic solution both in the short term as well as the long term.
