Automatic Pressure Regulator: Faster acting and quieter design eliminates "hunting" for correct drive pressure. New, improved stem and guide are precisely molded to assure efficient, trouble-free performance on all deep wells

Quality Construction: Close-grained cast iron pump body and base are specially treated to resist corrosion

Noryl Impellers: Precision-molded for perfect balance

Pressure Switch: High quality. Differential and cuttin/cut-out pressure settings are adjustable

Mechanical Shaft Seal: Precision-lapped and highly polished carbon-ceramic, stainless steel construction

Dustproof Cover: All electrical components are protected from dirt, dust and insects by a dustproof canopy

Dynamically Balanced Rotor: Rotor is diecast under high pressures for uniform performance, greater efficiency

Heavy-Duty Ball Bearings: Permanently lubricated sealed bearings are extensively tested to ensure extended life and smooth, quiet operation

Pump and Motor Shaft: Stainless steel for maximum corrosion resistance; one-piece threaded shaft for positive impeller drive and alignment
