According to Gorman-Rupp:
Pumps operating in parallel
- In parallel, two pumps can simultaneously discharge a greater amount of water than the individual one.
- Hence boost the discharge, if two pumps are connected in parallel.
- hnet = h1 = h2 = h3 = hn
- Qnet = Q1 + Q2 + Q3 +..... Qn
Pumps operating in series
- When two pumps are connected in series at the same flow rate the series pump yield high heads as compared to the individual heads produce by each pump.
- hnet = h1 + h2 + h3 +......hn
- Qnet = Q1 = Q2 = Q3 = Qn
