Series and parallel pump configurations are illustrated in Fig. 11.16a,b. The choice of series or parallel pumps for a particular application depends on many factors, including pipeline elevation profile, as well as operational flexibility.

Two typical options include parallel and series configurations of pumps. Specific performance criteria must be met when considering these options.

Pump in Parallel. With pumps in parallel, the flow rates are additive with a common head. The flowrate Qt is split between the inlet into Q1 and Q2. Each pump develops the same head H at the corresponding capacity. Thus, the first pump

Thus, the first pump at capacity Q 1 develops the same head H as the second pump at capacity Q 2. This commonality of head across parallel pumps is the most important feature of pumps installed in parallel.
