FEATURES

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
Precision machined, close grained cast iron pump body and base are specially treated to resist corrosion.

Noryl Impellers
Precision molded for perfect balance, and ultra-smooth for highest performance and efficiency.

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

Motor Windings
Superior insulation materials protect against excessive moisture and contaminants to ensure prolonged motor life.

Mechanical Shaft Seal
Precision lapped and highly polished carbon-ceramic, stainless steel construction. Internal design guarantees continuous water lubrication for maximum protection.

Dustproof Cover
All electrical components are protected from dirt, dust and insects by a dustproof canopy. Ventilating air cannot contaminate vital switching components. This eliminates the most common cause of motor failure.

Balanced Rotor
Rotor is die cast under high pressures for uniform performance and greater efficiency; dynamically balanced.

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

Pump and Motor Shaft
One piece threaded shaft for positive impeller drive and alignment. Shaft is stainless steel for maximum corrosion resistance.
