Goulds WS0712BF - 3/4 HP 230V Single-Phase Submersible Sewage Pump

The Goulds WS0712BF is a 3/4 HP, 230V single-phase submersible sewage pump from Goulds WS Series (Model 3887), part of Xylem’s Goulds Water Technology line. It is rated to handle solids up to 2" spherical through a 2" NPT threaded companion flange (3" flange available separately, order no. A1-3) 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: 3/4 HP
• Voltage / Phase: 230V Single-Phase, 60 Hz
• Speed: 1750 RPM
• Discharge: 2" NPT threaded companion flange (3" flange available separately, order no. A1-3)
• 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: 145 GPM
• 15 ft. TDH: 116 GPM
• 20 ft. TDH: 86 GPM
• 25 ft. TDH: 48 GPM

Construction:

• Impeller: cast iron, semi-open, non-clog, dynamically balanced with pump-out vanes for mechanical seal protection
• Casing: cast iron, flanged volute type, for maximum efficiency - designed for easy installation on an A10-20 slide-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, 300-series stainless steel, threaded design with a locknut to guard against damage on accidental reverse rotation
• Fasteners: 300-series stainless steel

Applications: Homes, water transfer, sewage systems, light industrial, dewatering/effluent, and commercial applications - anywhere waste or drainage must be disposed of quickly, quietly, and efficiently.

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.
