The Goulds GS is part of the Submersible Well Pump Series which is designed for use in minimum 4″ diameter water wells. Each pump end below is close coupled to a premium Centripro motor. Designed with a stainless steel construction for strength and corrosion resistance, these pumps feature two cast-in safety line loops for installer convenience.
Submersible Well Pump Series, GS pumps are built for dependable operation and long service life. The casing is corrosion resistant stainless steel, the impellers are Noryl and the diffusers are Lexan for excellent abrasion resistance, with all non-metallic parts being non-toxic and FDA compliant. The floating impeller stack provides superior sand handling and durability, while proprietary engineering polymer bearing provides additional abrasion and wear resistance. The enclosed upper bearing is mounted in a durable Noryl bearing spider for excellent abrasion resistance. The discharge head also includes a built-in stainless steel check valve.
The motor shaft has a six sided hex shaft design for positive impeller drive, while the motor adapter is Cast 303 stainless steel for rigid/accurate alignment while providing easy access to motor mounting nuts using a standard open end wrench. The motor is powered for continuous operation within the motor limits without damage. In general, the GS series units are easily field serviceable with common tools and readily available Goulds Pump Repair Parts.
Please note that 3-Wire pumps require a control box for operation. Control box sold separately.
