AUP Series Residential and light commerical wastewater removal, water transfer, circulation, and dewatering Durable stainless steel & engineering composite housing Non-clog vortex Impeller Detachable base strainer Large solid handling capability 2 years limited warranty Constructed with stainless steel and engineering composites with glass fiber reinforcement, Alita submersible pumps are both lightweight and corrosion resistant. With seal components utilizing high precision Silicon Carbide mechanical shaft seals with surface approaching the hardness of diamond, every model of Alita pumps are capable of operation under corrosive and abrasive conditions. AUP Series Submersible Water Pumps # Stainless Steel Motor Housing # Fiberglass Reinforced Engineering Composite Body # Detachable Base Strainer # Non-Clog Vortex Impeller For Free Passage of Large Solids & Fibers # Continuous Duty Submersible Pump FEATURES VORTEX IMPELLER FOR TOUGH-TORQUE FLOW Real Non-Clog performing volute impeller made of Fiberglass Reinforced Plastic (FRP) provides continuous operation with minimum abrasive wear and eliminates clogging and binding. Pumping is accomplished by induced high speed vortex which increase fluid pressure and minimize particle contact or entanglement of fibrous matter in wastewater and sludge. DETACHABLE STRAINER Dual use effluent and sewage handling design. Protect against damage from passing large rocks or metal objects. Safe guard for frog and fish. LARGE SOLID HANDLING PASSAGE For heavily polluted wastewater containing slender matter, long fibers and small or large solid particles. Suspended solids handling capacity: 35 mm (1.38 inch) in diameter ABRASION AND CORROSION RESISTANT Pump casing made of 304 stainless steel and fiberglass-reinforced engineering composite. The materials are strong and lightweight with high resistance to rust, corrosion, abrasion and impact. RUGGED MOTOR Motor housing: Stainless steel - corrosion resistant and good heat dissipation. Motor: Oil free (air filled electric induction motor). Designed for durable continuous operation. HIGH QUALITY MECHANICAL SEALS Double Silicon Carbide mechanical seals (impeller side) in lubricant chamber. SiC provide greater hardness (approaching diamond), withstanding of pumping pressure, corrosion and abrasion resistant, self-lubrication and temperature fluctuation tolerance. BUILT-IN OVERLOAD & THERMAL PROTECTION Self resetting automatic protection for motor against overload or overheat conditions.
