Pumps in Series Vs Pumps in Parallel Pharma

2021-8-5  Just tell me whether u need to connect pump in parallel or series?? if you connect pump in series then the 2nd pump should have a higher capacity than 1st pump, if you connect the pumps in parallel, then the coupling should be good, otherwise there will be lack of flow co-ordination between pumps.

2017-9-1  1. Pumps in series: Head is added, not the flow rate 2. Pumps in parallel: Flow rate is added, not the head However, for parallel case, not sure what I'm missing but find it not so intuitive to visualise why heads are not added. How the energy is dissipated in this case, by overheating the pumps? There could be two cases in parallel case, I.

Parallel and Series Pump Application Xylem Applied

2012-10-16  There may be many reasons to use parallel or series pumps instead of a single, larger pump. These may include: • Lower initial cost • Lower installation cost • Increased redundancy • Easier maintenance, • Lower operating cost, and • Significant energy savings.

Modeling Pumps in Parallel and Series Bentley

2018-12-26  Two pumps in series result in an effective pump with twice the head at the same discharge. For example, two pumps that can individually operate at 150 gpm at a head of 80 feet connected in parallel will have a combined discharge of 2·150 = 300 gpm at 80 feet. The same two pumps in series would pump 150 gpm at 2·80 = 160 feet of head.

Parallel operation of unmatched pumps When pumps operate in parallel, the flow rate at any given TDH point is additive. In the case of pumps that have identical operating characteristics, the flow would double. For example, two pumps that each had a capacity of 100 M3/hr at 50 M TDH would have a combined capacity of 200 M3/hr at 50 M TDH.
