Goulds LSP0311AV - 1/3 HP 115V Single-Phase Submersible Sump Pump

The Goulds LSP0311AV is a 1/3 HP, 115V single-phase submersible sump pump from Goulds LSP Series, part of Xylem’s Goulds Water Technology line. It is rated to handle solids up to 3/8" spherical through a 1-1/2" NPT discharge, running at 3450 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.

• Voltage / Phase: 115V Single-Phase, 60 Hz
• Speed: 3450 RPM
• Discharge: 1-1/2" NPT
• Solids Handling: 3/8" spherical
• Max. Submergence / Working Pressure: 10 ft
• Liquid Temperature: 104°F (40°C) maximum
• Power Cord: 10 ft standard, 20 ft optional

Flow Rate at Fixed Head (TDH):

• 10 ft. TDH: 29 GPM
• 15 ft. TDH: 20 GPM
• 20 ft. TDH: 5 GPM
• 25 ft. TDH: not rated at this head (shutoff head is approximately 20 ft)

Construction:

• Casing & Impeller: glass-filled thermoplastic
• Motor Casing & Fasteners: stainless steel
• Shaft: hard-coated 400-series stainless steel for improved corrosion resistance
• Shaft Seal: a double-labyrinth lip-seal system - three lip seals plus a V-ring, backed by an impeller counter-blade system that keeps solids away from the seal
• Bearings: upper and lower heavy-duty ball bearings, permanently lubricated for extended service life

Applications: Basement draining, water transfer, and dewatering.

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.
