Material of Vertical Turbine Pump
Bowl: Cast iron, Stainless steel
Shaft: Stainless steel
Impeller: Cast iron, Bronze or Stainless steel
Discharge head: Cast iron or carbon steel
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.
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.
QUESTION:
Solid shaft Pump
The shaft extension typically has a circular key way to pass on pump thrust, and a radial key way to transmit torque. The lower end coupling of the pump motor and the pump shaft is seen more often in tanks and shallow pumps, rather than deep-well operations.
What are the Differences Between Vertical Hollow Shaft (VHS) Pump Motors vs. Vertical Solid Shaft (VSS)?
The pumping industry was revolutionized with the creation of the vertical pump motor in the early 1920' s. This allowed for electric motors to be attached to the top of a pump, and the impacts were impressive. The installation process was simplified, and because it required fewer parts, was then less expensive. The efficiency of the pump motors increased by 30%, and because vertical pump motors are purpose specific, they are more durable and reliable than their horizontal counterparts. Vertical pump motors are generally classified by their shaft type, either hollow or solid.
Construction Features
Both types of pump motors are explicitly designed to operate vertical turbine pumps, and they typically have a P-base mount without feet. The construction features of vertical pump motors influence their application and maintenance needs.
Hollow Shaft
The most obvious difference between the two types of pump motors is that one has a hollow shaft, which changes its construction features from that of a solid shaft. In hollow shaft pump motors, the pump head-shaft extends through the motor shaft and is joined at the motor's crest. An adjusting nut is located on the peak of the head-shaft which streamlines the regulation of the pump impeller strength. A steady bushing is often installed to stabilize and center the pump shaft in the motor shaft. When started, the pump shaft, motor shaft, and steady bushing rotate concurrently, resulting in a mechanical stability comparable to that of a solid shaft motor. Vertical hollow shaft pump motors are the most commonly used motor for deep-well pumps, but they are also being selected for any pump operation that requires easy adjust-ability.
Solid Shaft
Vertical solid shaft pump motors are connected to the pump shafts near the bottom end of the motor. The shaft extension typically has a circular keyway to pass on pump thrust, and a radial keyway to transmit torque. The lower end coupling of the pump motor and the pump shaft is seen more often in tanks and shallow pumps, rather than deep-well operations.

Deep well pumps Axial-flow pumps
1. Short set turbines, typically designated as those shorter than 50' in length though there is no formal definition, are common in all industries and applications. The pump bearings may be lubricated by the water being pumped, which is typically the case in relatively clean water applications, or they may be lubricated by an external water source, oil, or grease, in applications where the pumpage is not suitable for bearing lubrication.
2. Deep well pumps are used for irrigation water in many parts of the country, as well as for drinking water supply.
3. Mixed-flow vertical turbines are large vertical turbines used in municipal water supply, large-scale industrial applications, desalination applications, as well as flood control. Depending on the impeller design, mixed-flow impellers may be enclosed (such as those shown in the diagram) or open (similar to those shown in the axial-flow diagram below).
4. Axial-flow pumps are low-head high-flow designs and aren't true turbines. However, from the outside looking in, axial-flow pumps look a lot like turbines, so we've included them in this category.
Axial-flow pumps are typically designed for heads no greater than approximately 30 Ft and are often designed to lift water just a dozen feet.

1.The inlet shall be vertical downward and the outlet horizontal above or under the base.
2.The impeller of pump is classified into enclosed type and half-opening type, and three adjustments: non-adjustable, semi adjustable and full adjustable. It is unnecessary to fill the water when the impellers are fully immersed in the pumped liquid.
3.On the basis o Pump, this type is additionally fit with muff armor tubing and the impellers are made of abrasive resistant material, widening the applicability of pump.
4.The connection of impeller shaft, transmission shaft, and motor shaft applies the shaft coupling nuts.
5.It applies water lubricating rubber bearing and packing seal.
6.The motor generally applies standard Y series tri-phase asynchronous motor, or YLB type tri-phase asynchronous motor as requested. When assembling Y type motor, the pump is designed with anti- reverse device, effectively avoiding reverse of pump.
