Max shut-off is the pressure at zero flow — the ceiling, not a working point. A dash means the pump will not deliver at that combination. Need help matching a duty point? See our jet pump sizing guide or call 1-888.510.4036.

Overview
A.Y. McDonald · 92000 / 93000 Series
Heavy-duty cast-iron centrifugal pump covering the widest horsepower range in its class — booster, irrigation, transfer, and HVAC duty from 1/3 through 3 HP, single and three phase, with heads to 150 ft.

Single & Three Phase
Heads to 150 ft / 65 PSI
Noryl or No-Lead Bronze Impeller
Four-Position Discharge
Rear Pull-Out Service
Pump sitting above the water? The Workhorse is an end-suction centrifugal — it runs best on a flooded suction or with a foot valve. If the pump must lift and self-prime from a pond, tank, or shallow source, choose the self-priming 8900 E-Series Sprinkler Pump.

Overview
The A.Y. McDonald 92000 (single-phase) and 93000 (three-phase) Workhorse is a heavy-duty end-suction centrifugal pump built to cover an unusually wide range of duties from one platform — booster systems, farms, light industry, lawn sprinkling, irrigation, air conditioning, cooling-tower circulation, and general water transfer.
Eight single-phase sizes and six three-phase sizes span 1/3 through 3 HP, so the pump is matched to the duty instead of the duty forced onto the pump. A precision-molded Noryl impeller (no-lead bronze available), NEMA square-flange motor, and cast-iron casing deliver dependable pressure to 150 ft of head. Rear pull-out construction services the motor and impeller without disturbing the suction or discharge piping. For non-potable service only.

Performance Curve
Key Advantages
Widest HP Range
1/3 through 3 HP in eight single-phase and six three-phase sizes — size precisely to head and flow instead of over-pumping.
Single & Three Phase
115/230 V single phase on smaller sizes, 230 V on larger, and 208/230/460 V three phase by wire selection.
Four-Position Discharge
Discharge rotates vertical or horizontal to suit the piping run, with three drain ports for complete winterizing.
Rear Pull-Out Design
Service the motor and impeller without breaking the suction or discharge connections — piping stays in place.
Noryl or Bronze Impeller
Precision-molded glass-filled Noryl standard; no-lead bronze impeller available for demanding service.
NEMA Square-Flange Motor
Capacitor-start, high-service-factor motor built to NEMA standards for ready local service availability.
Heads to 150 ft / 65 PSI
The 3 HP size develops 150 ft of shutoff head — strong pressure for booster and high-zone irrigation.
Cast-Iron, 175°F Rated
Heavy-duty cast-iron casing rated to 175°F maximum liquid temperature for continuous-duty transfer.

Suction & Priming — Read Before Installing
The Workhorse is an end-suction centrifugal pump, not a self-priming pump. Install it with a flooded suction (pump at or below the supply level) or with a foot valve and a primed suction line. If the installation requires the pump to lift and prime itself from an open source, select the self-priming 8900 E-Series Sprinkler Pump instead.
