Goulds WS1018B - 1 HP 208V Single-Phase Submersible Sewage Pump

The Goulds WS1018B is a 1 HP, 208V single-phase submersible sewage pump from Goulds WS Series (Model 3886), part of Xylem’s Goulds Water Technology line. It is rated to handle solids up to 2" spherical through a 2" NPT discharge, running at 1750 RPM. The table below shows this pump’s flow rate at four fixed total dynamic head (TDH) points, so you can match it to your specific lift and distance requirements.

• Horsepower: 1 HP
• Voltage / Phase: 208V Single-Phase, 60 Hz
• Speed: 1750 RPM
• Discharge: 2" NPT
• Solids Handling: 2" spherical
• Liquid Temperature: 104°F (40°C) continuous, 140°F (60°C) intermittent
• Power Cord: 20 ft standard, optional lengths available

Flow Rate at Fixed Head (TDH):

• 10 ft. TDH: 183 GPM
• 15 ft. TDH: 152 GPM
• 20 ft. TDH: 123 GPM
• 25 ft. TDH: 95 GPM

Construction:

• Impeller: cast iron, semi-open, dynamically balanced, non-clog design with pump-out vanes for mechanical seal protection (silicon bronze impeller available as an option)
• Casing: cast iron, volute type, for maximum efficiency - designed for easy installation on an A10-20 guide-rail or base-elbow rail system
• Mechanical Seal: silicon carbide vs. silicon carbide sealing faces for superior abrasion resistance, stainless steel metal parts, BUNA-N elastomers
• Shaft: corrosion-resistant stainless steel, threaded design with a locknut to guard against damage on accidental reverse rotation
• Fasteners: 300-series stainless steel

Applications: Home sewage systems, dewatering/effluent service, and water transfer.

Warnings: This pump must be connected to electrical service protected by a Ground Fault Circuit Interrupter (GFCI) where required by code. Failure to do so may result in serious personal injury or death and property damage.

Do not run this pump dry for extended periods or operate it outside its rated flow and head range. Follow the manufacturer’s wiring, grounding, and float-switch/control-panel instructions for your specific installation.
