Performance — Will It Do What You Need?
Find your suction lift and read across to the discharge pressure your sprinklers need. Each figure is gallons per minute from A.Y. McDonald’s published table; the last column is the shut-off pressure at that lift.

Reading it: zones needing 30 PSI with the water 10 ft below the pump get 32 GPM from the 1 HP, 51 GPM from the 1 1/2 HP and 56 GPM from the 2 HP. Lift costs flow at every pressure.
Zero flow is the shut-off point — a ceiling, not a working point. Curve figures are digitized from the published curve in the Pumps by Baker catalog, rev 3/26, p. 285, and rounded down; the GPM table is A.Y. McDonald’s printed performance, p. 286.
Before You Buy — The Limits That Decide the Fit
| Maximum pressure |
46 to 50 PSI at shut-off with no lift, falling as lift rises. |
| Suction lift |
Self-priming; published to 25 ft of lift. |
| Power |
Single phase: 1 and 1 1/2 HP switch between 115V and 230V (shipped at 230V); 2 HP is 230V only. |
| Pairing |
Single unit. |
