Goulds 25CS10 – 25 GPM, 1 HP Required, 7-Stage, 4" Submersible Well Pump End (Motor Not Included)

The Goulds 25CS10 is a 1 HP, 25 GPM 4" submersible well pump from Xylem’s Goulds Water Technology CS4 line, built with an all-stainless-steel water end for continuous-duty residential and light-commercial groundwater supply from 4" or larger wells. This water end (motor not included -- ordered separately) is built around a 7-stage pump end.

• Horsepower: 1 HP Required
• Stages: 7
• Recommended Flow Range: 8-33 GPM (Best Efficiency Point: 25 GPM)
• Discharge Connection: 1-1/4" NPT
• Minimum Well Diameter: 4"
• Rotation: Counterclockwise (CCW), viewed from discharge end
• Approx. Pump-End Length / Weight: 13.6" / 8 lbs
• Maximum Head with VFD: 460 ft (see performance curve)
• Wiring/Starting: Requires a separately purchased 1 HP, 4" NEMA-dimension submersible motor.

Construction:

• Discharge Head & Motor Adapter: Cast AISI 303 stainless steel for strength, durability, and rigid motor-to-pump alignment -- two cast-in safety line loops for installer convenience
• Casing, Bowl, Shaft & Shim: AISI 304 stainless steel, hex-shaft design for positive impeller drive; coupling is AISI 304 SS with powder-metal construction
• Impeller: Noryl® -- FDA-compliant, corrosion-resistant, non-toxic engineered polymer
• Diffuser: Lexan® -- FDA-compliant engineered polymer, resistant to abrasion and wear
• Bearings: Proprietary engineered polymer bearings; upper bearing spider is Noryl® GFN2
• Check Valve: Delrin® poppet with a BUNA (FDA-compliant) seal and AISI 302 SS retaining ring -- top-serviceable, spring-loaded, screws into the discharge head for easy removal on drain-back systems without disassembling the pump

• Cable Guard: AISI 304 stainless steel
• Pipe Connection: Quad-Lock Technology -- 4 permanently roll-formed grooves for durable, secure sealing
• Sand Handling: Face-clearance, floating impeller stack -- field-proven for over 50 years of superior sand-handling durability

Applications: Residential and light-commercial water wells, farm and irrigation wells, and deep-well water supply systems requiring dependable, sand-tolerant, all-stainless-steel submersible service.

Installation note: field-serviceable with common tools. Follow the pump manufacturer's wiring and grounding instructions; motors must be sized and protected per the specifications above.
