Motor Horsepower: 0.5 HP

Voltage: 115V

Wire Count: 2 Wire

Diameter: 4 inch

Shipping Weight: 33 lbs

Universal Product Code: 697666450531

Powered for Continuous Operation: All ratings are within the working limits of the motor as recommended by the motor manufacturer. Pump can be operated continuously without damage to the motor.
Field Serviceable: Units have left hand threads and are field serviceable with common tools and readily available repair parts.
Sand Handling Design: Our face clearance, floating impeller stack has proven itself for over 40 years as a superior sand handling, durable pump design.
FDA Compliant Non-Metallic Parts: Impellers, diffusers and bearing spiders are constructed of glass filled engineered composites. They are corrosion resistant and non-toxic.
Discharge Head/Check Valve: Cast 303 stainless steel for strength and durability. Two cast-in safety line loops for installer convenience. The built-in check valve is constructed of stainless steel and FDA compliant BUNA rubber for abrasion resistance and quiet operation.
Motor Adapter: Cast 303 stainless steel for rigid, accurate alignment of pump and motor. Easy access to motor mounting nuts using standard open end wrench.
Stainless Steel Casing: Polished stainless steel is strong and corrosion resistant.
Hex Shaft Design: Six sided shafts for positive impeller drive.
Engineered Polymer Bearings: The proprietary, engineered polymer bearing material is strong and resistant to abrasion and wear. The enclosed upper bearing is mounted in a durable Noryl® bearing spider for excellent abrasion resistance.

Important: Any well with a high static water level may allow the pump to operate off the curve and outside its recommended range. We recommend using a "Dole" flow restriction valve to throttle the pump to prevent upthrust damage to the pump and motor. The maximum flow must be restricted to within the pump's recommended operating range.

Installation Tips

Installation Brief

This 4 inch submersible well pump should be installed to match its 115V, 2 wire, 1 phase electrical requirements and intended operating range.

Confirm the pump model, 4 inch diameter, and 115V 2 wire 1 phase motor match the installation requirements.
Install the pump in the well and use the two cast-in safety line loops as provided on the discharge head.
Make electrical connections for the 2 wire motor according to the applicable installation instructions and code requirements.
Verify the pump will operate within its recommended range.
If the well has a high static water level, restrict maximum flow within the pump's recommended operating range to help prevent upthrust damage.
