The following additional issues should be considered when installing a centrifugal pump that is supplied from a trailer:
- Minimize the length of the flex lines, as the trailer's
flexible transfer hose adds even further to the overall piping length connected
to the suction fitting. The longer the piping length, the greater the chance
for heat leak and cavitation problems.
- Make sure the trailer transfer hose is supported in the middle of
its length to prevent the hose weight from applying unnecessary stress on the
suction fitting.
- Use a "witch's hat" strainer in the suction line. Be sure that the open surface area of the strainer is 1.5 times the diameter of the suction piping. A differential pressure gauge should be used across the suction strainer.
