When dealing with pumps in your industrial pump operation, it’s important to make sure all the gears are in place. At Cortech Engineering, we’re all about helping pump users get the most out of their equipment and maximize efficiency in every application. In this article, we want to highlight some of the most common mistakes made in industrial pump operations.
- Operating the Pump in Reverse
All pumps are designed to run with either a clockwise or counter-clockwise rotation, depending on the type of pump. A common mistake is made when the pump is operated in the reverse rotation of its design. This is especially problematic for ANSI pumps with threaded shafts and impellers that have no way to prevent the impeller from backing off.
- Ignoring the Operating Manual
This is perhaps the biggest mistake we see, and it is easy corrected. Pump owners and all operators should take the time to review the instruction and operating manual (IOM) before using the pump. It should regularly be referred to during operation so that it is run correctly and maintained as needed. Every pump is a little different and it takes time to understand how to operate it for optimal results and increased lifespan.
- Forgetting to Put Oil in the Bearing Housings
It’s very important to know that a majority of pump manufacturers do not put oil in the pump bearing housings before they are shipped. There are many restrictions against shipping with the oil (a hazardous material) inside the housings; therefore, operators need to make sure that they put the oil in the bearing housings before operating the pump. Otherwise, damage will occur without proper lubrication.
- Running a Second Pump without System Adjustments
Too many operators may decide to install a secondary pump and run it parallel next to an existing pump, thinking it will increase the output. This works some of the time; However, it often causes more problems than it solves. Make sure the system is designed to handle and control two (or more) pumps before using multiple parallel pumps.
- Confusing Suction Pressure with NPSHA
Net Positive Suction Head Availability (NPSHA) and suction pressure are not the same thing. It is very important to understand how the impeller and fluid intake process works in any given pump, so that is properly installed, operated, controlled, monitored and maintained. This will help you generate the desired flow rate, operate the pump efficiently and maximize the life of the equipment.
