<strong>SHURflo</strong> <strong>Bronze</strong> Pedestal Self-PrimingFlexible Impeller PumpsRefer to form L-4082 for General Operating <strong>and</strong> Safety Instructions.Description<strong>SHURflo</strong> bronze, pedestal, self-priming, positive-displacement, flexible impeller pumps provide a nearly pulseless flow with nometal-to-metal contact. This pedestal pump drive series includes a 303 stainless steel drive shaft with heavy-duty ball bearing<strong>and</strong> carbon graphite bushing, providing for direct drive or pulley operation. Features include: bronze <strong>and</strong>/or brass pumpbody, cam <strong>and</strong> cover; st<strong>and</strong>ard Buna-N mechanical seal with carbon ceramic faces <strong>and</strong> Nitrile impeller.Uses: H<strong>and</strong>le a wide range of industrial, marine, agricultural <strong>and</strong> commercial applications where non-abrasive fluidscompatible with pump wet-end construction component materials are pumped. Pumps are suitable for the transfer ofnon-lubricating fluids, mild abrasives, fluids containing small particles in suspension, <strong>and</strong> a wide variety of viscous fluids suchas petroleum-based oils, silicone greases, <strong>and</strong> hydraulic fluids. These units are ideal for water drainage transfer, barrelemptying, machine coolant recycling, <strong>and</strong> an assortment of related utility activities.NOTE: Flexible impeller failure will occur immediately if pump is run dry, <strong>and</strong> this is not covered under warranty. Use cautionto not touch the pump if you have dry run it, because it will be extremely hot.• Flows up to 36.5 GPM at 3450 RPM.• Maximum discharge pressure is 25 PSI (60 ft. of head).• Max. RPM: 3450.• Suction lift to 13.5 ft.• Buna-N mechanical seal with carbon ceramic wear faces <strong>and</strong> 18-8 stainless steel components.• Maximum viscosity up to 500 SSU <strong>and</strong> 25 PSI (60 ft. of head) at 1725 RPM or run at reduced speeds to h<strong>and</strong>le a wide rangeof pump fluid viscosities (up to 2500 SSU) <strong>and</strong> specific gravity (up to 1.3). DO NOT pump oils or petroleum derivatives withoptional neoprene impellers. (Maximum torque loads are found in the performance chart.)• Pumps can operate bi-directionally (reversible).• Temperature range with Nitrile impellers is 0°F - 180°F (optional neoprene impellers is 15°F - 130°F).• Includes a 303 stainless steel drive shaft with heavy-duty ball bearing <strong>and</strong> carbon graphite bushing, providing for directdrive or pulley operation.BRONZE MODELS – Excellent for water-based fluids. Features include: bronze <strong>and</strong>/or brass pump body, cam <strong>and</strong> cover; st<strong>and</strong>ardBuna-N mechanical seal with carbon ceramic faces <strong>and</strong> Nitrile impeller. Wet-end parts are constructed from bronze, brass, Nitrile,carbon, ceramic <strong>and</strong> stainless steel (18-8, 303 <strong>and</strong>/or other 300 series).REPAIR IMPELLERS AND OPTIONS – St<strong>and</strong>ard impellers are Nitrile, <strong>and</strong> they <strong>and</strong> the optional neoprene impeller can belocated in the repair parts list pages in this manual.NOTE: <strong>Bronze</strong> <strong>and</strong> <strong>316</strong> stainless steel flexible impeller pumps are also available as close-coupled models for custom installation. They areequipped with motors.FLEXIBLE IMPELLER PUMPSWARNING: Do not use to pump flammable or explosive fluids such as gasoline, fuel oil, kerosene, etc. Do not use in flammable<strong>and</strong>/or explosive atmospheres. When pumping hazardous or dangerous materials, use only in a room or area designated for thatpurpose. For your protection, always wear proper clothing, eye protection, etc. in case of any malfunction. For proper h<strong>and</strong>ling techniques<strong>and</strong> cautions, contact your chemical supplier, insurance company <strong>and</strong> local agencies (fire dept., etc.). Failure to comply with this warningcould result in personal injury <strong>and</strong>/or property damage.Source: Owner’s Manual L-4095 (12/09)74www.shurfloindustrial.comEffective 1/1/2011Form 45-SHU
