I know TDH is Total discharge head minus total suction head (plus if it is suction lift).My feeling is that if you calculate the TDH then you can determine the flow rate from the pump curve. For a cen

We have 2 Pumps runs parallel. Pump Discharge before Turaround 70-72#. Pump Discharge right after Turnaround 65# of last year. We have about 7# differences ever since. First we thought that might be

Reliability of the supply of compressed air to your process(es) is what really matters.Variable speed drives add additional potential reliability risks with no (yes NO!) efficiency advantage for powe

It is the responsibility of the valve manufacturer to establish the pressure ratings for their products. The design professional should consult the manufacturer's published information and not assum

Here is some more information:The elevation difference between the pump and the reservoir (really an 18,000 gal concrete tank) is about 300 ft. The well pumps through the distribution system to the t

Remember that NPSH and cavitation are two different issues. When there is head falloff because of insufficient NPSH, the cavitation is so advanced that it blocks the flow passages. Damage can occur

Irecall a reference made to the rotation of EMD Marine Engines and the relationship to fresh water pumps on the engine. I recall seeing, in a parts book I believe, a drawing referring to the "Construc
