Goulds 18HS10 – 18 GPM, 1 HP Required, 8-Stage, 4" Submersible Well Pump End (Motor Not Included)

The Goulds 18HS10 is a 1 HP, 18 GPM 4" submersible well pump from Xylem’s Goulds Water Technology HS line, built for continuous-duty residential and light-commercial groundwater supply from 4" or larger wells. This water end (motor not included -- ordered separately) is built around an 8-stage pump end.

• Horsepower: 1 HP Required
• Stages: 8
• Recommended Flow Range: 6-28 GPM (Best Efficiency Point: 18 GPM)
• Discharge Connection: 1-1/4" NPT
• Minimum Well Diameter: 4"
• Rotation: Counterclockwise (CCW), viewed from discharge end
• Approx. Pump-End Length / Weight: 14.3" / 4.5 lbs
