Ashland Water Group EFSWJ5 Shallow Well Jet Pump 1/2 Hp

Product Description

The ASHLAND WATER GROUP EFSWJ5 is a cast iron shallow well jet pump rated at 1/2 HP for residential and light commercial water supply applications. It delivers up to 7 GPM and is designed for wells with a suction lift up to 25 feet. The motor runs on dual voltage — 115 or 230 volts, factory set at 230V — giving installers flexibility when matching existing electrical service. A built-in overload protector guards the motor against thermal damage. The stainless steel shaft, heavy-duty bearings, balanced rotor, mechanical seal, and insulated windings make this a durable, field-serviceable unit for licensed plumbing and water system contractors.

The EFSWJ5 is suited for shallow well water supply systems in residential settings where the static water level stays within 25 feet of the pump. Typical installations include private well systems, irrigation supply, and pressure booster setups. The corrosion-resistant nozzle and venturi assembly are appropriate for use with hard or mildly aggressive water. Suction connection is 1-1/4 inches and discharge connection is 1 inch, fitting standard threaded piping common in residential plumbing.

Installation Notes

Installation should be performed by a licensed plumber or water systems contractor in accordance with local plumbing codes and IPC guidelines. Shut off all electrical power at the breaker before wiring or servicing the unit. Verify supply voltage matches the selected motor tap before energizing — the pump ships set for 230V. Prime the pump and suction line fully before first startup to prevent dry-run damage to the mechanical seal.
