Goulds WW0511 - 1/2 HP 115V Single-Phase Submersible Sewage Pump

The Goulds WW0511 is a 1/2 HP, 115V single-phase submersible sewage pump from Goulds WW Series (Model 3872), part of Xylem’s Goulds Water Technology line. It is rated to handle solids up to 2" spherical (full-vortex impeller) through a 2" NPT discharge, running at 1550 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: 1/2 HP
• Voltage / Phase: 115V Single-Phase, 60 Hz
• Speed: 1550 RPM
• Discharge: 2" NPT
• Solids Handling: 2" spherical (full-vortex impeller)
• Liquid Temperature: 104°F (40°C) continuous, 140°F (60°C) intermittent
• Power Cord: 10 ft standard, 20 ft optional

Flow Rate at Fixed Head (TDH):

• 10 ft. TDH: 69 GPM
• 15 ft. TDH: 34 GPM
• 20 ft. TDH: not rated at this head (shutoff head is approximately 18 ft)
• 25 ft. TDH: not rated at this head (shutoff head is approximately 18 ft)

Construction:

• Impeller: glass-filled thermoplastic, full-vortex design with pump-out vanes for mechanical seal protection
• Casing & Base: rugged glass-filled thermoplastic for strength and corrosion resistance
• Motor Housing: cast iron for efficient heat transfer, strength, and durability
• Mechanical Seal: carbon-rotary/ceramic-stationary faces, BUNA-N elastomers
• Bearings: upper and lower heavy-duty ball bearings
• Fasteners: stainless steel

Applications: Residential sewage systems, dewatering, and water transfer - 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.
