Star ES07S 3/4 HP Cast Iron Shallow Well Jet Pump - Made

The Star ES07S is a 3/4 HP cast iron shallow well jet pump built to draw water from single-pipe shallow well installations. Designed for suction depths between 0 and 25 feet, it supplies a steady flow for residential properties needing up to 930 GPH (3,520 LPH) and water pressure up to 50 PSI.

At the center of the unit is a continuous-duty uni-frame 56 motor that operates on either 115V or 230V power. It utilizes a capacitor start mechanism to deliver strong starting torque, while integrated thermal overload protection guards the internal wiring against excessive heat. The pump housing is made of cast iron and includes a carbon/ceramic mechanical shaft seal, an ejector for easy servicing, and an integrated pressure switch.

Routine maintenance and setup are supported by practical physical features. A dedicated priming port simplifies adding water to the system before starting, and an accessible drain plug allows you to clear the housing quickly when preparing for winter. Every unit is 100 percent factory tested before leaving the facility and is backed by a 2-year limited warranty.

Because this model is built strictly for shallow wells, it cannot operate with suction lifts greater than 25 feet or on two-pipe deep well configurations. Buyers with deeper water sources will need a dedicated deep well pump instead.

Verdict: The Star ES07S is a dependable choice for homeowners who need a durable cast iron pump for single-pipe shallow wells up to 25 feet deep. Its flexible dual-voltage motor, integrated service ports, and factory-tested construction provide consistent daily water pressure.
