There are several different variations of pumps in active use today and they vary widely from each other in working principle, design, function, capacity, useability, features, etc. However, all pumps will break down from time to time.
When they do, the pump must be repaired or even replaced, depending on the reason why it broke down. Get to know the primary reasons that lead to a pump’s failure, so that you can take quick and appropriate actions to remedy the situation as quickly as possible.
Poor Design and Construction
All water pumps must be designed and manufactured for the respective environments in which they will be installed and operated. Their design and construction must meet the durability requirements to withstand the expected pressure which originates from their own pumping actions, as well as the surrounding environmental factors.
Cheaper, generic pumps from dubious brands are often significantly cheaper, but those initial savings come at a much higher long-term cost. Poorly made heavy duty industrial pumps in particular will break down frequently, before going out of commission permanently soon after. It’s always a good idea to do your research and invest in adequately equipped pumps from a reputed brand that offers extensive warranty.
Pump cavitation is not easy to explain as even the experts do not yet agree on a universal and comprehensive definition. Nevertheless, the problem itself can be easily defined in less scientific terms. When air bubbles are both formed and collapsed in rapid succession within any fluid or liquid being pumped, the resulting changes in pressure will also create constant shockwaves within the pump.
Over time, cavitation can and most often will cause severe damage to the pump’s metallic parts, and the seals. This can be a very serious issue, as pump cavitation is a potential accident waiting to happen in an industrial setting. Fortunately, this is a preventable problem and you can find out how to prevent pump cavitation here.
Using even the world’s best pump for a job that it was not built to handle will lead to problems. This is the most common reason why pumps break down due to overloading. If you are using a pump that does not have the capacity to handle the workload it is being used to handle, overloads and malfunctions are inevitabilities. If the type of pump being used was not originally designed to handle the type of liquid or fluid it’s pumping, that too can only lead to failures.
Take some time and get to know your options for the different needs first. Then, choose a type and capacity that well exceeds your expected requirements. Ensure that the power supply used is adequate (look for the energy consumption ratings). Do make sure that all employees operating the different pumps are adequately trained to operate that specific make and model.
Mishandling and wrong usage are among the most common reasons responsible for pump breakdowns. Finally, get your pumps inspected for the first signs of damage or failure to prevent the problems even before they become damagingly apparent.
