• 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 is a rugged, one-piece unit. Specially treated to resist corrosion. Drain port provided for easy winterization.
• Precision Machined Diffusers - for faster priming
• Mechanical Shaft Seal - Precision lapped and highly polished carbon-ceramic, stainless steel construction. Internal design guarantees continuous water lubrication for maximum protection
• Polycarbonate Impellers - Precision molded for perfect balance, and ultra-smooth for highest performance and efficiency
• Motor Windings - Superior insulation materials protect against excessive moisture and contaminants to ensure prolonged motor life
• 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 - Shielded, permanently lubricated 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
