Non-Clog Wastewater Pump Quality System ISO9901 Certified Environmental Management System ISO14001 Certified FLAP VALVE TYPE 1 Air-Powered Double-Diaphragm U.S. Patents # 5,996,624 & 6,241,487 INTAKE/DISCHARGE PIPE SIZE ENGINEERING, PERFORMANCE & CONSTRUCTION DATA 0 to 260 gallons per minute (0 to 988 liters per minute) No-lube, no-stall design. This SANDPlPER ® is designed specifically for the processing of municipal and industrial wastewater. Its solids handling capability and special features make it the ideal choice for safe, sealless pumping of waste materials. • Sealless. • Self-priming. • Designed to easily pump abrasive, viscous slurries. • Swing-type check valves handle spherical solids to 3". The W15 model designation indicates a wastewater unit (W) which pumps roughly 15,000 gallons of water per hour(15). The W15-3 has 3" flange connections. And the W15-4 features 4" flange connections. When specifying or ordering, please state model designation, as well as type. • Easy-access check valve clean-outs. • In-line serviceable wet end. ESADS+Plus: Externally Serviceable Air Distribution System. • Top suction - bottom discharge porting. All types shown below are available for both W15-3 and W15-4.

Shows good solvent, oil, water and hydraulic fluid resistance. Should not be used with highly polar solvents like acetone and MEK, ozone, chlorinated hydrocarbons and nitro hydrocarbons. NEOPRENE All purpose. Resistant to vegetable oils. Generally not affected by moderate chemicals, fats, greases and many oils and solvents. Generally attacked by strong oxidizing acids, ketones, esters, nitro hydrocarbons and chlorinated aromatic hydrocarbons. RUPPLON® (Urethane) Shows good resistance to abrasives. Has poor resistance to most solvents and oils. EPDM Shows very good water and chemical resistance. Has poor resistance to oil and solvents, but is fair in ketones and alcohols. Santoprene® Injection molded thermoplastic elastomer with no fabric layer. Long mechanical flex life. Excellent abrasion resistance. For specific applications, always consult the Warren Rupp Chemical Resistance Chart.
