Common Human errors on buying a Pump

Avoiding this can greatly improve the efficiency and reliability of your pumping system and avoid costly damage and safety issues. Check out the list below to see if you have made these common mistakes.

  1. Underestimating the IOM

                   For each issue in the field, we were asked if the end user had read the documentation and user manual (IOM), so this issue was easily avoided. Many of the top 20 errors can easily be avoided by reading and monitoring the IOM before installing the pump. To mention it seems to be the stupidest mistake. Many industry experts consider themselves ignorant when reading the guidelines. It is always a good idea to read the IOM, even if no other employee reads it.

2. Operating the pump backward

The second most common mistake is reversing the pump, essentially reversing. This occurs when the pump must run clockwise (CW) but must run counterclockwise (CCW) or vice versa. I see this at least once a month. This is a serious problem for pumps that cannot interfere with the fan support, such as American National Standards Institute (ANSI) pumps with fan propellers and shafts.

3.NO oil in bearing

                    Contrary to popular belief, pump manufacturers do not add oil to the pump casing prior to shipment. This is because in most cases it is illegal to install an oil pump in your home. At least three US government agencies restrict this practice because oil is subject to dangerous goods regulations, especially in transit manufacturers generally avoid adding oil to the pump housing because the end user does not know which type or brand to choose. In addition, oil can easily leak, leak or become contaminated during transportation and installation. Most pump manufacturers, including manuals and pumps, issue specific warnings to top up bearing oil. Despite these precautions, starting a new oil-free pump is one of the most common mistakes end users make, and far more frequent than 40 years ago. The resulting damage is often significant and leads to unnecessary downtime and additional material and labor costs.

4.Pressure of Suction  with NPSHA

          A common misconception is that the pump “sucks” liquid from the suction system into the pump. This can be done remotely if the liquid is plastic (I think the fan is pressing on the eyes), but the system on the suction side is sufficient to direct the liquid into the bomb. If the suction-side system does not have sufficient “signal strength” (power scale), the analog telephone “call” is lost or faded. In other words, the pump is hollow.

5. Dual pump system

          “In a typical scenario, someone sees an additional pump installed and decides it is easier to start the solution and use a second pump. Two pumps are installed in one system. For those who are not trained in this, parallel operation of the second pump will logically increase the flow. In some cases, this may work, but in most cases, it will. Does not work. Unless the system is designed to operate two (or more) pumps at the same time (parallel), it is not necessary to use both pumps for problems.
