Jim Nelson’s Helpful Hints: The New Troubleshooting Tool

Throughout the year we diagnose hundreds of pump and equipment problems over the phone and have found that in most cases it isn’t a pump problem, but rather a system problem. Sometimes the best tool you can use to help us determine your pumping issue is a camera.

By sending us a few well snapped pictures from your camera, of the pump and/or system, will give us a greater understanding on diagnosing your pumping issue. In addition to visuals, if we know the suction pressure, discharge pressure, and air inlet pressure, most problems can be solved quickly.

Jim Nelsons Helpful Hints: Diaphragm Cycle Life vs. Maximum Flow Rate

I often receive phone calls from end users about diaphragm cycle life and the first few questions I ask are:

  1. What pump are they using?
  2. What chemicals are they using and at what temperature?
  3. Is it a suction lift application or a flooded suction?
  4. At what flow rate are they operating the pump?

After discussing these questions I find that several customers are running the pump at full throttle instead of selecting a larger pump in the beginning process of the pump selection.

Operating a larger pump at half throttle would extend the diaphragm life, consume less air consumption and overall provide less wear and tear on the equipment.
