Vertical Turbine Pump Introduction:

Vertical shaft turbine (commonly referred to as “vertical turbine”) pumps are unique in that the impellers are intended to be submerged in the water source. They are used for installations where the water source is below the pump impellers. These pumps have a bowl assembly which contains several impellers on a vertical shaft – where the discharge of one impeller directly feeds the suction of the next impeller, and so on – a column assembly built to a specified length, and a discharge head assembly which holds the motor or right-angle gear drive. In a mechanical room, the discharge head assembly of a typical vertical turbine pump is the only visible part of the pump.

The VTP pump line is normally designed to operate in wells or sumps. Its bowl assembly consists primarily of a suction case or bell, one or more pump bowls and a discharge case. The pump bowl assembly is positioned in the sump or well at a depth to provide the proper submergence.

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.

After leaving the diffuser casing, the water passes in a vertical column pipe and rises toward the surface. The rotating shaft within the column is propped at 3 to 5 foot intervals using sleeve bushings that are set within the column and they are lubricated by the water as it moves past them. The pump also has a discharge head at the surface which allows the flow to change direction toward the discharge pipe. An upright standing high thrust A.C. motor is fitted above the pump’s discharge head.

Advantage:

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.
