Pumps Operation in Series and Parallel.
## Centrifugal pump operation is joined in series or in parallel to meet certain operational requirements. They are joined in series when the delivery head requirements are high as in the case of pumping in high-rise buildings or operating sprinkler systems etc. Two or more pumps may be joined in such a way that the delivery of one becomes the inflow into the other.
## Pumps Operation is joined in parallel when they have a common source and the pumping head is the same. In situations like pumping from rivers or a pond or dewatering foundations, pumps could be joined in parallel.
The pumps will now operate against the same head H = H1 = H2 =…. If the characteristics of the pumps differ too much, this relationship may not be applicable.
