Common Pump Formula - M.G. Newell
www.mgnewell.com(Net Positive Suction Head available) NPSHa = Pa ± h s – h fs – Pvp (+h s for flooded section) (-h s for suction lift) where: Pa = pressure absolute above fluid level (bar) h s = static suction head (m) h fs = pressure drop in suction line (m) Pvp = vapor pressure (bar a) Or
OPERATING AND MAINTENANCE MANUAL
www.montgomerycountymd.govJul 17, 2003 · any positive suction inlet pressure, reducing the amount of work done by the pump. For example, if the required discharge pressure is 120 PSI (8 BAR), and the inlet pressure is 45 PSI (3 BAR), the pump must only produce the difference in pressures of 75 PSI (5 BAR). This contributes to low engine and pump speeds with reduced maintenance.

QUICK GUIDE FOR PUMP SELECTION
www.dabpumps.comThis means that this pump will work correctly, always and when the level difference between the end of the suction pipe and the pump suction port is less than or equal to 6.5 m. In this example hs= 5 m, i.e. less than 6.5 m, hence the selected pump will work good. EXAMPLE 8 @ THEORETICAL SELECTION 2 STOREYS 1 STOREY hs=5m hg=hs+hi=5m+6m=11m hi=6m
