Powered for Continuous Operation:
All ratings are within the working limits of the motor as recommended by the motor manufacturer. Pump can be operated continuously without damage to the motor.
Field Serviceable:
Units have left hand threads and are field serviceable with common tools and readily available repair parts.
Sand Handling Design:
Our face clearance, floating impeller stack has proven itself for over 40 years as a superior sand handling, durable pump design.
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 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. 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 for positive impeller drive.
Engineered Polymer Bearings:
The proprietary, engineered polymer bearing material is strong and resistant to abrasion and wear. The enclosed upper bearing is mounted in a durable Noryl® bearing spider 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 pumps recommended operating range.
Goulds 18GS07422C is a 4 inch stainless steel submersible well pump rated for 18 GPM with a 3/4 HP, 230V, single-phase, 2-wire motor.
