Firefighting Applications Mutil-stage Vertial Turbine Fire Pump
With NFPA20 Standard Capacities 2500 Usgpm
This pump does come with a few disadvantages. Besides the
additional initial cost, these pumps can be challenging to service.
One must remove the pump or disassemble it, which often requires
use of a roof hatch in a room so that a crane can lift it out for
examination. Since these pumps are all custom-built, the lead times
can also be long – from 8 to 20 weeks depending on the manufacturer
and models. Special care must be made before operating a vertical
turbine pump for the first time – the shaft and impellers must be
properly adjusted to lift them off of the bowl casings prior to
Where the fire protection water source is located below ground or
deck level, the best technical pumping solution is the vertical
suspended multi stage turbine pump. With this type of unit the
impellers are fully immersed in the water maintaining prime at all
times. The pumps are driven by vertical electric motors or by
diesel engines through a right angle gearbox.
These pumps are helpful in areas where water is scarce, but also
when installing an above-ground water storage tank is not
desirable. An added advantage to a vertical turbine pump is that
almost any length and discharge pressure of the pump can be
ordered. Several impellers can be added for additional pressure.
When properly installed, there is no longer a concern about air in
the suction pipe, or any of the priming concerns. With each
additional impeller added, you are adding to the pump “churn” or
shut-off point on its curve, so additional unwanted pressure is
often seen at lower operational flows.
