These pumps are specifically designed and tested for fire service applications where reliability of performance is of vital importance. Split case pumps are characterized by:• Easy access to all working parts; • Rugged construction; • Liberal water passages; and• Efficient operation. Split case fire pumps are specified when the source of water is located above the surface of the ground and provides a positive suction pressure to the pump at any performance point. Single-stage or multistage pumps are available dependent upon discharge pressure requirements.Aurora split case fire pumps are built per the rigid standards of NFPA 20 and are listed by Underwriters Laboratories (UL) and approved by Factory Mutual (FM). Available in a broad range of operating pressures and flows from a minimum of 250 GPM, Aurora split case pumps can be driven by either an electric motor or diesel engine. Aurora’s UL-Listed, FM-Approved fire pump packages also include the system controller, with a full range of options and accessories available to complete the NFPA-compliant fire pump package. In addition to horizontal split case pumps, Aurora also offers split case performance in a vertical format. Vertical fire pumps provide distinct advantages over horizontal pump constructions.• Less floor space is required.• In-line piping arrangement allows piping in any direction in most cases.• Elevated motor protects against potential flooding if the pump station is in a low area. • Components are register-fitted to prevent misalignment.3WWW.AURORAPUMP.COMSPlit CASe FiRe PUMPSPump Features1. Computer Machined major components with 360 degree registered fits to assure concentricity of parts.2. Integral Bearing Arms eliminate bearing misalignment and simplify maintenance.3. Enclosed Impeller Design provides high efficiency and performance.4. Dynamically Balanced Impeller is keyed to the shaft and secured by adjustable shaft sleeves.5. Double Suction Impeller balances hydraulic thrust loads.6. Cast Iron Drip Rim Base directs condensation and any stuffing box leakage to drain.7. Short Bearing Span holds shaft deflection to .002" at face of stuffing box at maximum load.8. Internal Water Seal Passages between volute and stuffing box cannot be damaged.9. Interwoven, Graphite Impregnated T.F.E. diagonally cut packing rings seal the pump shaft.10. Stuffing Boxes are extra deep for proper sealing. Split packing glands simplify packing maintenance.11. Double Row Thrust ball bearing.12. Grease Seals and nonsparking neoprene rotating slingers protect both bearings during pump operation and washdown.13. Bearings selected for 50,000 hour minimum life at maximum load. Average bearing life 5 x minimum.14. Split Case Design simplifies disassembly. The suction and discharge piping and shaft alignment are not disturbed.15. O-Ring Sealed Shaft Sleeves prevent corrosion of the shaft. This eliminates the need for stainless steel shafts.16. Case Wearing Rings and throttle bushings protect the casing from wear and are easily and inexpensively replaced.17. Bronze Shaft Sleeve prevents shaft wear, is slip fit over the shaft, keylocked, and extends the entire length of the seal box.18. Certified Performance Test with Positive Suction Pressure is provided for each fire pump for customer approval. Pumps are also hydrostatically tested per NFPA 20 at no less than 250 psi.6543217891011131415 16171812HORizOntAl SPlit CASeVeRtiCAl SPlit CASe800 AIRPORT ROAD, NORTH AURORA, ILLINOIS 60542 WWW.AURORAPUMP.COMBecause we are continuously improving our products and services, Pentair reserves the right to change specifications without prior notice.AF-02-1033 11/26/12 © 2012 Pentair Ltd.
