WebNov 19, 2015 · "Deadhead" is a carryover term from centrifugals that does not apply to PDs. A PD pump cannot be "deadhead-ed" without destroying something (shaft seals, casing, discharge piping, motor, etc.). I'd like to understand the motor side more if I could. Probably should be a completely different thread. WebA centrifugal pump is dead-headed when it is operated with no flow through it, for example, with a closed discharge valve or against a seated check valve. If the discharge valve is closed and there is no other flow path available to the pump, the impeller will churn the same volume of water as it rotates in the pump casing.
WebCentrifugal pumps are used in series to overcome a larger system head loss than one pump can compensate for individually.
