NFPA20 Standard Firefighting Pump Sets With Diesel Engine Driven
Vertial Turbine Fire Pump Up To 5000GPM
Vertical Turbine Pump Introduction:
vertical turbine pump is designed to successfully operate in a
multitude of water sources from wells to oceans.
Markets served: Urban and rural municipal water, irrigation,
chemical processing, primary metals, petroleum, power plants,
mines, food processing, offshore platforms and more
Handles raw water intake, liquid transfer, cooling water
circulation, booster service, storm water, flood control, marine,
process services, volatile fluids, condensate, fuel pumps and mine
dewatering
Turbine bowls can be staged in series to produce the necessary
discharge pressures. Constructed out of cast iron, bronze,
stainless steel or other machineable materials. Wear rings are
available to provide a renewable surface. Open line shafts – Allows
shaft bearings lubrication
How it Works:
The vertical turbine pump is normally driven by an AC electric
induction motor or a diesel engine via a right angle drive. The end
of the pump consists of a rotating impeller that is joined to a
shaft and guides the well water into a diffuser casing known as a
bowl.
Pumps with multi-stage arrangements use several impellers on a
single shaft to generate higher pressure that would be required for
pumping water from deeper wells or where higher pressure (head) is
required at ground level.
A vertical turbine pump works when water comes through the pump
from the bottom through a bell-shaped device known as a suction
bell. The water then moves into the first stage impeller, which
increases the velocity of the water. The water then moves into the
diffuser casing directly above the impeller, where the high
velocity energy is transformed into high pressure. The diffuser
casing also guides the fluid into the next impeller located
directly above the diffuser casing. The process goes on through all
the stages in the pump.
