Non-Clog Wastewater Pump Quality System ISO9001 Certified Environmental Management System ISO14001 Certified FLAP VALVE TYPE 1 Air-Powered Double-Diaphragm ENGINEERING, PERFORMANCE & CONSTRUCTION DATA No-lube, no-stall design 0 to 140 gallons per minute (0 to 530 liters per minute) 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 2". The W09 model designation indicates a wastewater unit (W) which pumps roughly 9000 gallons of water per hour(09). The W09-2 has 2" flange connections. And the W09-3 features 3" 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 W09-2 and W09-3. All types available for W09-2 and W09-3. When specifying or ordering, please state model designation, as well as type.

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 chemcals, fats, greases and many oils and solvents. Generally attacked by strong oxidizing acids, ketones, esters, nitro hydrocarbons and chlorinated aromatic hydrocarbons. EPDM Shows very good water and chamical 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. RUPPLON® (Urethane) Shows good resistance to abrasives. Has poor resistance to most solvents and oils. For specific applications, always consult "Chemical Resistance Chart", Technical Bulletin. Warren Rupp, SANDPIPER® and Rupplon® are registered tradenames of Warren Rupp, Inc. *Definite reduction in service life. **Minimal reduction in service life at ends of range.
