The Biggest Problem with Pump Life

Posted on 13 June 2019

Did you know that 90% of pump failures occur because the wrong pump has been selected or installed?

Your business can spend thousands of dollars trying to maintain a particular type of pump and even replace parts because it is not performing to its optimal capacity. All this money, time and energy is then wasted. Whether you are looking to install a pump or have already done so and worry that it is the wrong piece of equipment for your application, let us look at how Global Pumps can remedy this situation for you.

Why the Right Pump Matters

A pump is a pump, right? It simply moves fluids from one location to another, so surely the cheapest option is the best? It is understandable why you might think this way, especially when you are trying to save your business or your bank account from unnecessary expenditure. But in the long run, installing the right pump for the job provides you with a number of advantages:

  1. Safety: With the right pump, you can be confident that there will be no leaks in your system.
  2. Maintenance: As mentioned above, if you are having problems because the wrong pump has been installed, then you will see failure in valves, impellers and other components of your pump because it is being used for an application which it was not designed for. This quickly incurs significant expenses to remedy through part replacement and maintenance. The right pump limits the amount of maintenance required and therefore reduces costs over the long term.
  3. Efficiency: With the right pump installed, you will see huge gains in terms of efficiency. This means pumping larger volumes of material, faster. Whatever your end goal is, this means that you are getting the job done in a timely manner, which will further reduce costs. More than this, efficiency also delivers a reduction in energy usage. With the correct pump then, you reduce operating costs.

 

How the Wrong Pump Causes Failure

When looking at the specifics of why the wrong pump causes failure, there are a large number of reasons which can result in breakdowns, part erosion and even hazardous outcomes. Just a small selection of why these pumps fail, includes:

1. Pumps built from materials which are designed to handle water like liquids and is being used to transport abrasive or corrosive substances. This means that a pump is being exposed to difficult environments which exceeds its manufacturing limits. The result? Failure and leakage.

2. The net positive suction head (NPSH) is incorrectly selected before installation. The NPSH is used to measure the likelihood of cavitation brought about by flashing (evaporation). Again, this occurs when the pump is being asked to handle higher suction lifts for which it was not designed. See our related blog on why your suction line is important.

3. Incorrect evaluation of the best efficiency point (BEP). The best efficiency point informs pump users of the ideal parameters to get the best out of their pumps. When this is exceeded, problems such as cavitation then occur. See our related blog: what is cavitation?

4. Significant environmental changes. This happens when a pump owner changes the materials being pumped, thinking that the already installed pump can handle such a change. However, if the pump is not designed for that specific scenario, then failure will occur.

5. Low quality pump installation also leads to early failure and other problems. Unless the pump has been vetted by an experienced company such as Global Pumps, then you cannot be certain that it will perform to the highest of standards.

6. Likewise, due to budget constraints, owners sometimes prefer the cheapest option. But if the cheapest option is not designed for those specific circumstances, it will fail.

7. In other cases, owners may feel familiar with the specific type of pump and therefore use the same model across a factory. This works in some situations; however, if those pumps have been asked to handle different materials at different pressures and flow rates, then this blanket solution will not work.
