NFPA20 Standard UL Listed FM Approved 500GPM @ 312 feet Horizontal
Split Case Fire Pump
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.

HSC Pumps are engineered for reliable operation upon demand. All
fabricated parts are standardized and accurately machined for true
alignment, increasing overall durability. Precision balancing of
all rotating components provides mechanical dependability, reliable
operation and minimal maintenance. Impellers are constructed with
double inlets that practically eliminate end thrust while boosting
operating efficiency.ic tests.
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.
