We get this question all the time, How long should my pump last? So I decided to put together this quick and easy rule of thumb guide. Please understand that every single pumping application out there is unique. There are likely thousands of factors that contribute to the overall life expectancy of a pump. This guide is intended to be used as a point of reference as to what can be typically expected out of a pump.
The first rule
Not every pump is created equal. A common real life example, in nearly all duplex pump systems (two pumps) almost never do both pumps fail at the same time. Although, in a typical configuration, they each shared 50% of the work load. I like to say that even if a pump fails it does not mean that a better pump exists. I go back to an old saying, fool me once, shame on you, fool me twice, shame on me. If your pump has failed, take a second look at the application, verify the pump is a good fit. I also recommend doing a little research on the pump, and if you find positive reviews, then consider going with the same model again. A little common sense goes a long way in making the decision to switch to another pump.
The List
If your pump exceeds the Average Life Expectancy listed below, you have exceeded the average life expectancy and your pump was likely well selected for the application.
