Vibration is never good for any mechanical system and can put unnecessary strain on your entire pump. Vibration is most commonly caused by cavitation, running at excessive RPM, impeller imbalance due to blunt force, or operating outside the pump’s optimal efficiency range. Continuing to run a vibrating pump eventually leads to pump bearing wear, allowing the shaft to shift laterally from its mounting position causing it to flex and eventually fail.

Water Hammer

When operating a fluid dispersal system, there is risk of shock to that system from hydraulic forces exerted by the fluid being pumped. Imagine dropping a stone in a pond – the force applied by the stone sends shock-waves far away from the initial point of impact. This same force can be exerted on your system by a sudden stop in fluid movement, called a Water Hammer. When valves are shut off at high RPM, a shock-wave can be sent back down the pipes to the pump which can exert shearing forces on your shaft and potentially lead to a bend or complete breakage of the pump shaft. You can remedy this by lowering the RPM or disengaging the PTO before shutting off the valves. To further insure against damage from a Water Hammer, you can install a relief valve to vent the excess pressure and prevent it from reaching your pump.

These are only some of the most common factors that can lead to water pump failure, download our Centrifugal Pump Guide for more information on proper maintenance practices. With adequate care and mindful operation, the life of your pump and shaft will be long and fruitful.
