WebNov 18, 2015 · Generally speaking, for a PD pump, the max discharge pressure is when something breaks, or the motor gets overloaded and dies. BigInch (Petroleum) 20 Nov … Shutoff (a.k.a. zero-flow or dead-head) occurs at about 130 ft. The design condition falls very close to the pumps best-efficiency-point (BEP). Provided there is adequate NPSHa, the pump will operate down to approximately 60 ft of head and produce a flow of approximately 1380 GPM at 60 ft. See more For the sake of example, today were going to look at a selection made for the following design condition: 1,000 GPM at 100 ft. Here is one possible pump selection that might be a good fit for that operating condition: … See more The first piece of information provided by a pump curve is the flow that the pump will develop at any given operating head. The curve that provides this information is called the pump … See more In addition to head and flow, most pump performance curves will also provide efficiency information. See more The maximum (17) and minimum (15) trim curves also tell us the possible conditions that the pump could be modified to meet in the future by installing an impeller of a larger or smaller different trim.
