Best 1.5 hp irrigation pumps
Researched by Deal.ai's shopping agent across stores on November 2, 2026. Prices below are today's.
Top pick: Goulds GT15 IRRI-GATOR. Goulds is the name irrigation installers trust, and the GT15 is the classic 1.5 HP centrifugal sprinkler pump — 115/230V, rated 4.9/5 from buyers, and it's the one I'd put on a permanent lawn system.
Who the others suit:
- AQUASTRONG 1.5 HP — the easiest all-rounder if you want big flow (4250 GPH, 108 ft head) and a simple plug-in setup for a sprinkler zone.
- Pearl Thor 15 / THOR 15F16S — solid cast-iron centrifugal choice when you want a 1.5" FNPT inlet and 115/230V flexibility.
- Acquaer 1.5 HP shallow-well — light-duty jobs: draining, transfer, a small garden.
- Pearl self-priming shallow-well jet pumps — for pulling from a shallow well or cistern with pressure control built in.
- Munro LP150B — heavy, high-flow commercial duty.
Check your suction lift and pipe size before buying: centrifugal pumps need a flooded or near-flooded suction, jet pumps handle a lift.
