Pump Efficiency: positive_displacement_reciprocating
Centrifugal and positive displacement pump efficiency data — BEP efficiency, head, specific speed, and impeller type by pump classification and flow rate
| pump type | flow gpm | description | efficiency pct (%) | head ft (ft) | hp range | notes |
|---|---|---|---|---|---|---|
| positive_displacement_reciprocating | 10 | Reciprocating positive displacement pump (plunger/piston) | 82 | 1,155 | 3-15 | Ns and impeller_type not applicable. Efficiency nearly independent of pressure. Head = 500 psi typical. |
| positive_displacement_reciprocating | 25 | Reciprocating positive displacement pump (plunger/piston) | 85 | 1,155 | 7.5-30 | Chemical metering and injection service. |
| positive_displacement_reciprocating | 50 | Reciprocating positive displacement pump (plunger/piston) | 87 | 925 | 15-60 | Process and pipeline service. |
