Powered for Continuous Operation: All ratings are within the working limits of the
motor as recommended by the motor manufacturer. Pump is designed for continuous-duty operation without
damage to the motor.
Field Serviceable: Units have left hand threads and are field serviceable with
common tools and readily available repair parts for easy maintenance.
Sand Handling Design: Our face clearance, floating impeller stack
(a design that allows the impellers to move slightly to handle sand and abrasives) has proven
itself for over 40 years as a superior sand handling, durable pump design. Its multi-stage construction
also helps deliver pressure for moderate well depths.
FDA Compliant Non-Metallic Parts: Impellers, diffusers and bearing spiders are
constructed of glass filled engineered composites. They are corrosion resistant and non-toxic.
Discharge Head/Check Valve: Cast 303 stainless steel to provide a stainless steel
discharge head for strength and durability. Two cast-in safety line loops for installer convenience. The
built-in check valve is constructed of stainless steel and FDA compliant BUNA rubber for abrasion
resistance and quiet operation.
Motor Adapter: Cast 303 stainless steel for rigid, accurate alignment of pump and motor.
Its steel construction and corrosion resistance help support long-term reliability. Easy access to motor
mounting nuts using standard open end wrench.
Stainless Steel Casing: Polished stainless steel is strong and corrosion resistant.
Hex Shaft Design: Six sided shafts (a six-sided shaft for improved impeller drive) for
positive impeller drive.
Engineered Polymer Bearings: The proprietary, engineered polymer bearing material
(bearings made from durable, abrasion-resistant polymer materials) is strong and resistant to abrasion and
wear. The enclosed upper bearing is mounted in a durable Noryl® bearing spider (an impeller made from a strong,
corrosion-resistant polymer) for excellent abrasion resistance.
Important: Any well with a high static water level may allow the pump to operate off the
curve and outside its recommended range. We recommend using a "Dole" flow restriction valve to throttle the
pump to prevent upthrust damage to the pump and motor. The maximum flow must be restricted to within the
pump's recommended operating range. Typical uses include residential water systems and rural properties. It also
fits applications such as livestock watering and agricultural tasks.
Benefits
Durable stainless steel construction resists corrosion
Sand handling design helps improve performance in sandy well conditions
The Goulds Water Technology 25GS10412C is a GS series 4" submersible
well pump in the Goulds family of series 4 submersible pumps, built for homeowners
with private wells, agricultural property owners, light commercial managers, and contractors who need
dependable sand handling and long-term corrosion resistance. This 1 HP, 230V, 3 Wire with Control Box
model delivers 25 GPM and sits within a GS series range that includes minute sizes equipped
with different hp motors and flow capacities for different residential and light commercial needs, and features stainless steel construction with a
polished stainless steel casing, cast 303 stainless steel discharge head and motor adapter, and a built-in
check valve for durable construction and corrosion resistance.
Construction and Materials
Its floating impeller stack (a design that allows the impellers to move slightly to handle
sand and abrasives) is designed for sand handling, while glass-filled engineered composite impellers,
diffusers, and bearing spiders provide corrosion-resistant, non-toxic construction suited for continuous-duty
operation and easy maintenance with common tools.
Its multi-stage design uses 7 stages to deliver higher pressure performance, illustrating how Goulds 4 submersible pumps provide
the pressure needed for demanding residential, agricultural, and light commercial water systems.
Motor and Electrical Features
The motor includes built-in lightning and surge protection.
Additional features include left-hand threads for field serviceability, a
hex shaft (a six-sided shaft for improved impeller drive) for positive impeller drive, engineered polymer
bearings (bearings made from durable, abrasion-resistant polymer materials) for abrasion resistance, and two
cast-in safety line loops for installer convenience.

What size well pump is this?
It is a 4 inch diameter submersible well pump.
Can this pump run continuously?
Yes, it is stated to be powered for continuous operation within the motor manufacturer's working limits.
How does this pump handle sand?
It uses a face clearance, floating impeller stack design described as a durable sand handling design.
What materials are used in the pump construction?
It features a polished stainless steel casing, cast 303 stainless steel discharge head and motor adapter, and glass-filled engineered composite non-metallic parts.
Does the pump have a built-in check valve?
Yes, it has a built-in check valve constructed of stainless steel and FDA compliant BUNA rubber.
What wire size information is provided for this model?
For a 1 HP, 3-wire, 230V, single-phase motor, the listed maximum distances are 371 ft for 12 gauge, 592 ft for 10 gauge, 937 ft for 8 gauge, 1458 ft for 6 gauge, 2324 ft for 4 gauge, and 3689 ft for 2 gauge.
This 3-wire submersible well pump includes a control box and should be installed according to the Goulds instruction literature and applicable electrical codes.
Confirm the pump matches the application requirements for 25 GPM, 1 HP, 230V, single-phase, and 4 inch diameter installation.
Install the pump and connect the 3-wire motor to the included control box following the product instruction manual.
Use the provided wire gauge guidance for the distance from the service entrance to the motor.
Complete the discharge connection and verify the built-in check valve and safety line loop features are properly accounted for during installation.
If the well has a high static water level, restrict maximum flow to keep operation within the recommended pump range.
