14/12/2012 When configured in parallel, the flow rate of 1200 gpm is split equally through each pump (400 gpm each), and each pump develops a head of 800 ft. Thus, the total flow is: Q T = 400 + 400 + 400=1200 gpm. And the common head across each pump is H 1 = H 2 = H 3 = 800 ft. To conclude, pumps in series have a common flow rate with heads being additive.احصل على السعر
Parallel operation of unmatched pumps When pumps operate in parallel, the flow rate at any given TDH point is additive. In the case of pumps that have identical operating characteristics, the flow would double. For example, two pumps that each had a capacity of 100 M3/hr at 50 M TDH would have a combined capacity of 200 M3/hr at 50 M TDH.احصل على السعر
