Campbell 7509JP Deep Well Jet Ejector 0.5 Hp

Product Description

The CAMPBELL 7509JP is a single-stage deep well jet ejector designed for use with 0.5 HP jet pump systems. The ejector assembly creates the suction needed to draw water from depths in the 40 to 80 foot range by converting pressure energy into velocity energy through a venturi nozzle and diffuser configuration. This component is installed downhole in the well casing as part of a deep well jet pump setup. It is typically handled by licensed plumbers or water well service contractors working on residential potable water supply systems.

This ejector is suited for single-pipe or two-pipe deep well installations where static water levels fall between 40 and 80 feet below grade. It is paired with a compatible above-ground jet pump motor and pump body to form a complete deep well water supply system. Typical applications include rural residential homes, farmsteads, and light commercial buildings that rely on drilled wells for their primary water source.

Key Features

• Single-stage ejector design matched to 0.5 HP pump configurations
• Engineered for deep well applications with water depths from 40 to 80 feet
• Venturi-based operation requires no downhole moving parts, reducing maintenance needs
• Designed for installation inside the well casing as part of a two-pipe jet pump system

Compatibility

Designed as an OEM-style replacement ejector for single-stage deep well jet pump systems rated at 0.5 HP with operating depths in the 40 to 80 foot range.

Installation Notes

Installation should be performed by a licensed plumber or certified well contractor in accordance with local plumbing codes and applicable IPC guidelines. Shut off all power to the pump system and relieve system pressure before removing or installing the ejector assembly. Ensure the nozzle and diffuser are free of debris before lowering the ejector into the well casing. Do not overtighten threaded connections on plastic or brass fittings, as this can crack the ejector body or distort the sealing surfaces.
