Goulds WS0312BHF - 1/3 HP 230V Single-Phase Submersible Sewage Pump

The Goulds WS0312BHF is a 1/3 HP, 230V single-phase submersible sewage pump from Goulds WS Series (Model 3887BHF, High Head), 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 3500 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: 1/3 HP
• Voltage / Phase: 230V Single-Phase, 60 Hz
• Speed: 3500 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: 86 GPM
• 15 ft. TDH: 48 GPM
• 20 ft. TDH: not rated at this head (shutoff head is approximately 18-19 ft)
• 25 ft. TDH: not rated at this head (shutoff head is approximately 18-19 ft)

Construction:

• Impeller: cast iron, enclosed, non-clog, dynamically balanced with pump-out vanes for mechanical seal protection - a smaller-diameter, higher-speed design that trades some low-head flow for substantially greater head capability
• 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
• Bearings: upper and lower heavy-duty ball bearings
• Power Cable: severe-duty rated, oil and water resistant, with an epoxy seal at the motor end for a secondary moisture barrier
• Fasteners: 300-series stainless steel

Applications: Homes, water transfer, sewage systems, light industrial, dewatering/effluent, and commercial applications requiring higher discharge head than the standard 3886/3887 series.

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.
