Horizontal split case pumps are the most common type of fire pump. 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 500 GPM, NM split case pumps can be driven by either an electric motor or diesel engine. NM’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.

Commercial Field: five-star hotels, hospitals, schools, supermarkets, office buildings, large-scale commercial complex, highway tunnels, subway stations, railway stations, airports; Fire-fighting Engineering Companies;

 

 

How It Works:

The most common split case pump is a single-stage, between bearing, non-self-priming centrifugal volute pump. The design of the pump allows for easy removal of the pump’s top casing to enable easy access to the pump’s components without interfering with the motor or the piping system.

The independent bearing casing allows for easy maintenance without the need for removing the pump’s top casing. The pump’s double volute design minimizes the radial load on the shaft, increasing component life and reducing vibrations to provide a quiet operation.
