Horizontal split case pumps are the most common type of Fire Pump. These pumps are specially tested for fire-service applications where reliability of performance is of vital importance. They are characterized by easy access to all working parts, rugged construction, liberal water passages, and efficient operation. They are specified when the source of water is located above the surface of the ground and will provide a positive suction pressure to the pump at any performance point. There are several capacity ratings of Aurora approved Fire Pumps available ranging from a minimum of 250 GPM. Single stage or multi-stage pumps are available dependent upon discharge pressure requirements.

Aurora complies with PERFORMANCE requirements for fire pump service with its standard production pumps. Therefore, to the Fire Pump user this feature means:

1. Lower initial cost.

2. Quicker delivery from stock.

3. Parts interchangeability with Aurora pumps specified elsewhere in your building reduces spare parts inventory and simplifies maintenance.

The fact that Aurora pumps meet the rigid requirements of Underwriters Laboratories and Factory Mutual Research is testimonial to the high quality of Aurora Pump products.

Aurora Pump offers the only true line of vertical split case Double Suction type pumps approved and listed for fire service. Vertical Fire Pumps provide distinct advantages over horizontal pump constructions.

1. Less floor space required.

2. Inline piping arrangement allows piping in any direction in most cases.

3. Elevated motor protects against potential flooding if the pump station is in a low area.

4. Components are register fitted to prevent misalignment.

Aurora's Horizontal Splitcase Fire Pumps: Model 481 (single stage) and Model 485 (two-stage) Fire Pumps can be electric- or diesel-driven. One major advantage of the diesel-driven Fire Pump is that it provides uninterrupted service in the event of a power failure. Aurora's diesel driven fire pump packages come standard with an Aurora Splitcase Fire Pump, driver and controller. We offer additional items such as Main Relief Valve, Waste Cone, Fuel Tank and Accessories, Test Manifold, Hose Valve, Flow Indicator & Jockey Pump and Controller that might be necessary for individual jobs, but are not standard.
