Pump Curves: diaphragm_pump_1in_full
Representative pump performance curves for common HVAC and plumbing pump families — total head (ft), efficiency (%), BHP, and NPSHr at multiple flow rate (GPM) operating points
| pump family | flow gpm | bhp (hp) | efficiency pct (%) | notes | npshr ft (ft) | total head ft (ft) |
|---|---|---|---|---|---|---|
| diaphragm_pump_1in_full | 5 | 1.2 | 38 | Low flow; efficiency reflects air consumption overhead | 3 | 76 |
| diaphragm_pump_1in_full | 10 | 1.8 | 48 | Mid-range; AODD efficiency limited by air overhead losses | 4 | 70 |
