35GS10412CL

Key Features

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.

Overview

Goulds Water Technology Overview

The Goulds Water Technology 35GS10412CL 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 model delivers 35 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 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.
