WebApr 24, 2013 · Centrifugal pumps are frequently operated in parallel to achieve higher system flows, to enhance system flexibility or to provide greater pump redundancy and hence better system availability. For very large projects, limited availability of sufficiently large pumps or limits on driver size or electrical starting current may dictate the use of … WebJul 3, 2007 · Therefore, pushing out the PQ curve along head (series) will usually result in a higher resulting flow than pushing the PQ curve along flow (parallel). The exception lies with pumps with very large head and low flow (RD-30, RD-05, etc.) in which case you would probably get better flow by using parallel pumps. WebFor identical pumps with similar functions, if the pumps arranged in series, the total head is increased without a change to maximum discharge. On the other hand, for pumps arranged in parallel to one another, the discharge is increased without any changes to maximum head.

WebThe objective of this experiment is to determine the operational characteristics of two centrifugal pumps when they are configured as a single pump, two pumps in series, and two pumps in parallel. 4. Method. Each configuration (single pump, two pumps in series, and two pumps in parallel) will be tested at pump speeds of 60, 70, and 80 rev/sec. WebTheoretical background A pump is a device to move fluid through mechanical action. Pumps consume energy to perform mechanical work in order to move the fluid the frictional force and gravitational force. Pumps are often used together to enhance either the flow rate or the delivery pressure beyond that available from the single pump. Two typical options include …

WebPumps while operating in series would develop other properties irrespective of heads, they will develop some excess flowrate when compared to them individually, Each pump … WebPumps running in parallel will increase flow (Q), but not head (H). Pumps are operated in parallel when two or more pumps are connected to a common discharge line and share the same suction conditions. Water pressure boosting applications use, for example, pumps from the CR range to ensure steady flow through a common discharge line.
