Hi Gents,
briefly, we got re circulation pump (D&S) (35 l/s 15.4m & SH-19m) for a tank capacity of 1500 cu.mtr with single suction & discharge (please find attached sketches. pump was giving 10 psi at discharge which was overlooked and modified the system to 8 suction &12 discharge as attached.
After tested, of course it has been found that field data not matched with manufacturer data.
crucial things is when the system reduced to very low profile as single suction and single discharge and pump was over sized, then why it gives low flow?
could anyone diagnose the actual error ( please be noted, velocity head and pressure gauges elevation also included in the calculations to obtain the tabulated results.
Thank you.
