Double Suction Split Case Fire Fighting Water Pump COS-F150-6050
(2000gpm 110m)
Description
A fire fighting water pump is a centrifugal pump which is used for
pumping fire-fighting water. Fire-fighting pumps can be designed
for transportable use (e. g. on fire-fighting vehicles or as
portable fire pumps) or for stationary use (e. g. hydrants,
sprinkler systems).
The XSF series Horizontal Split Case Fire Fighting Water Pumps are
engineered based on advanced hydraulic model. All fabricated parts
are standardized and accurately machined. Precision balancing of
all rotating components provides mechanical dependability, reliable
operation and minimal maintenance. Impellers are constructed with double inlets that practically
eliminated end thrust while boosting operating efficiency.
Split Case Fire Fighting Water Pump feature a heavy shaft and short bearing span that reduces shaft
deflection to a minimun, providing longer packing and bearing life
and lower maintenance costs, while requiring less floor space.
Fire pumps play a vital role as the first response to a fire
situation, saving countless lives and property from destruction.
They are usually found in manufacturing and industrial facilities,
housing complexes, power plants, schools, hospitals, airports,
commercial buildings and offshore oil platforms. A fire pump is the
component responsible for supplying the adequate water pressure to
fire sprinklers and hose standpipes in order to control or contain
a fire. Ruhrpumpen’s centrifugal pumps combine the latest in
hydraulic design with decades of application experience to meet
today’s fire security requirements
Fire fighting water pumps are usually in idle state. They are only
operated for testing water / water mist systems or foam systems,
and in the event of fire. This is why reliable start-up and fast
ramp-up to full pump power output (also after prolonged standstill)
is of particular importance.
Features
* Exceptional hydraulic efficiencies
* Double entry reduce end thrust force, increase efficiency and
bearing life
* Stainless steel impellers and shaft as standard
* Reduced efficiency degradation
* Comply to FM and/or UL standards (NFPA 20, UL448 and FM1311)
