NFPA20 Horizontal Split Case Fire Pump For Schools / Supermarkets 1500gpm@300 Feet
A split case pump is a type of centrifugal pump in which the pump’s casing is split into two separate chambers.
This type of pump is different from an inline pump or an end suction pump in which the discharge nozzle and the
suction nozzle are both included in one chamber.
There are two main types of the split case pump. When the casing is split along a vertical plane with respect to the
impeller, it is referred to as a vertical split case pump. When the casing is split along a horizontal plane, it is referred
to as a horizontal split case pump. The later type of casing design is more economical in applications that require
significantly higher flows, and its impeller can be supported using bearings on two sides, which is an advantage for
larger, higher flow pumps.
The split case pump has both the discharge and suction connections in the lower half of the pump casing, in an opposing
configuration to each other. The pump’s impeller is normally mounted on a shaft that is supported by bearings on two sides.

Advantage:
First-Class international technical standards
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.
