Goulds 50L03 – 3 HP Required, 4-Stage, 6" Submersible Pump End (Motor Not Included)

The Goulds 50L03 is a 3 HP, 4-stage 6" submersible pump end from Xylem’s Goulds Water Technology L Series, built in stainless steel for high-capacity water supply from 6" and larger wells. This is a water end only -- the motor is ordered and packaged separately and must be sized to at least 3 HP with a 4" NEMA-dimension diameter.

• Minimum HP Required: 3 HP (motor not included -- ordered separately)
• Stages: 4
• Required Motor Diameter: 4"
• Recommended Flow Range: 17-70 GPM (Best Efficiency Point: 50 GPM)
• Discharge Connection: 3" NPT
• Minimum Well Size: 6" / 8"
• Rotation: Counterclockwise (CCW), viewed from discharge end
• Approx. Length / Weight: 20.6" / 25 lbs
• Pump Body Diameter: 5.59"
• Maximum Fluid Temperature: 140°F (60°C)

Construction:

• Discharge Head, Check Valve Support & Motor Adapter: Cast stainless steel (ASTM CF-8 / AISI 304)
• Impeller & Diffuser: AISI 304 stainless steel -- new design for improved efficiency
• Shaft, Shaft Coupling & Spacer: AISI 431 stainless steel -- removable, heavy-duty splined coupling for maximum load-carrying capability; four-fluted shaft eliminates impeller keys
• Check Valve: Stainless steel, positive-sealing, built into the discharge head
• Bearings: Replaceable silicon carbide bearings for excellent abrasive handling and wear resistance; thrust bearing is PTFE + graphite
• Shaft Sleeve & Bushing: Tungsten carbide
• Wear Rings: Technopolymer PPO (engineered polymer)
• Elastomers: EPDM
• Strainer, Tie Rod & Cable Guard: AISI 304 stainless steel
• Fasteners: All stainless steel

Applications: High-capacity commercial, municipal, agricultural, and industrial water supply from 6" and larger wells -- irrigation, dewatering, water treatment, and other applications requiring sustained high-volume groundwater delivery.

Installation note: water end and motor are ordered and packaged separately -- select a compatible motor at or above the minimum HP shown, matching the required motor diameter above. A control box is required for single-phase motors; a magnetic starter with Class 10 overloads is required for three-phase units.
