Starite ProJet™ SN Series Features The ProJet SN Series Pumps provide excellent performance with good pressure for wells to 25' deep. Self-priming after the priming chamber has been filled with water. Used in Shallow Well / Tank Applications to feed water systems & sprinkling for homes, farms and cottages. Key Features & Benefits for Starite ProJet SN Series Pumps • Quality construction: Close-grained cast iron body. Drain port provided for easy winterizing. • Built-in Jet: High-strength Lexan nozzle and venturi for maximum resistance to corrosion and abrasion. Clean-out plug provided for ease of service. • Noryl impeller: Precision-molded for perfect balance...ultra-smooth for highest performance and efficiency. • Precision-Molded Diffuser: Pump primes faster, handles more air, with multi-port, precision-molded, reinforced polypropylene diffuser. • Mechanical Shaft Seal: Precision lapped and highly polished carbon-ceramic, stainless steel construction. Internal design guarantees continuous water lubrication. • Motor Winding: Superior insulation materials protect against excessive moisture and contaminants...assure prolonged motor life. • Balanced Rotor: Die-cast under high pressures for uniform performance and greater efficiency, dynamically balanced. • Heavy-Duty Ball Bearings: Shielded, permanently lubricated bearings, 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. • Dust-proof cover: All electrical components are protected from dirt, dust and insects by a dust-proof canopy; ventilating air cannot contaminate vital switching components. • Pressure Switch: Professional quality, allows cut-in adjustments ( 30/50 Preset from Factory ) Pump Construction Information • Body: Close-grained cast iron • Nozzle: High-strength Lexan® • Venturi: Lexan • Impeller: Noryl® • Diffuser: Reinforced polypropylene • Shaft: One-piece threaded, 416 grade stainless steel • Base: Steel, 12 gauge Operation & Use Guidelines • Maximum Liquid Temperature: 140°F • Maximum Inlet Pressure: 50 PSI • Average Priming Time (in minutes) at 15 Feet: SNC = 2.3; SND = 1.7; SNE = 1.3; SNF = 1.1 • Average Priming Time (in minutes) at 25 Feet: SNC = 6.4; SND = 4.4; SNE = 4.4; SNF = 2.6
