Vertical Turbine Pump Introduction
A vertical turbine pump is a special centrifugal pump designed to
draw water from a reservoir or well that is deep underground. It is
one of the two major types of turbine pumps and it’s at times
referred to as a line-shaft turbine pump or deep well turbine pump.
The two major types of turbine pumps are submersible turbine pumps
and vertical turbine pumps. While the electric motor in a
submersible pump is located underwater at the pump’s base, the
motor in a vertical turbine pump is located above ground and it’s
connected through a vertical shaft to the impellers at the base of
the pump. However, word “turbine” in the pump’s name is somewhat
inappropriate because this type of pump doesn’t have anything to do
with a turbine. Applications
The vertical turbine pump is primarily used in cases where a
submersible pump cannot be used because the flow exceeds the range
of turbines. These types of pumps are also used to supply water to
municipalities that depend on ground water instead of surface
water, and to supply fire water and make-up water for industrial
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

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

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
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.
First-Class international technical standards.
CNP NM FIRE is the first member of NFPA from China pump's
manufacturers.and won the UL,FM international fire certification
for fire pump products.
First-Class testing and inspection equipment.
UL certification represents the world's highest technical standards
of fire certification,but also means that certified fire products
must withstand the most extreme,harsh test process,the purpose of
certification designed to verify whether the product meets the
performance,safety and quality requirements,so as to achieve the
purpose of property protection.
NM fire obtained fire diesel engine UL1247 and fire pump UL448
witnessed laboratory accreditation,fully proved that the company in
terms of hardware and software strength,are to meet the strict
requirements of UL certification.
