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 plants.
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
Deep well, irrigation, sumps, condensate, can pump requirements, fire service, municipal, industrial
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.
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.
