This base class represents multiple identical pumps that are piped in parallel. An optional check valve in series with each pump is included. This class is used to construct the various multiple-pump models within Buildings.DHC.Plants.Combined.Subsystems.
In a parallel arrangement, all operating units have the same operating point. This allows modeling the multiple pumps with a single instance of any class derived from Buildings.Fluid.Movers.BaseClasses.PartialFlowMachine. Hydronics are resolved with mass flow rate multiplier components.
