For Water Use Ductile Cast Iron Made Centrifugal Fire Pump With UL/FM/NFPA20 Certification
Horizontal Split Case:
Horizontal Split Case (HSC) pumps are given their name due to the “split”” design of the casing, where the casing cover can be lifted off of the pump to expose the internal components. These components include the impeller, bearings, pump shaft, and so on. HSC pumps have two bearings, located on either side of the impeller, which are useful to withstand the large amount of vibration and thrust forces often caused by water turbulence in the suction piping.
The pump casings are often designed to handle higher working pressures, and are often heavier. The durability of the HSC design allows the pump to be used for very large water flows – often in excess of 5000 GPM. It should be noted that an HSC pump is not always mounted horizontally, it is possible to have the same durability design features and have the pump designed to be mounted vertically.
The fire pump starts when the pressure in the fire sprinkler system drops below a threshold. The sprinkler system pressure drops significantly when one or more fire sprinklers are exposed to heat above their design temperature, and opens, releasing water. Alternately, other fire hoses reels or other firefighting connections are opened, causing a pressure drop in the fire fighting main.
Fire pumps are needed when the local municipal water system cannot provide sufficient pressure to meet the hydraulic design requirements of the fire sprinkler system. This usually occurs if the building is very tall, such as in high-rise buildings, or in systems that require a relatively high terminal pressure at the fire sprinkler in order to provide a large volume of water, such as in storage warehouses. Fire pumps are also needed if fire protection water supply is provided from a ground level water storage tank.
Types of pumps used for fire service include: horizontal split case, vertical split case, vertical inline, vertical turbine, and end suction.
