Vertical Turbine Pump

Vertical Turbine Pumps are available in single-stage or multi-stage impellers with mixed flow or axial flow directions, providing high flow rates and delivery pressures. The main components of the pump include:

1. Bowl Assembly

2. Column Pipe

3. Discharge Head

Vertical Turbine Pump can pump liquids from deep wells or pits for firefighting to water used in industrial processes, supplying water to cooling towers in power plants, pumping water for irrigation, and increasing water pressure in municipal pumping systems. Suitable for almost all types of water pumping work.

Advantages of Vertical Turbine Pumps

1. Used for pumping liquids from deep wells or reservoirs, these pumps are ideal for urban water supply, agricultural irrigation, and other industrial processes requiring pumping from deep wells.

2. Vertical turbine pumps offer advantages in their design, as they can be tailored to meet specific efficiency requirements. They are available in a variety of materials, including cast iron, stainless steel, and brass, to handle a wide range of liquids, including water, oil, and chemicals. Additional features include adjustable impellers, blower diffusers, and bearings for increased efficiency and performance.

How Vertical Turbine Pumps Work

1. Vertical turbine pumps are designed to be submerged in the liquid to be pumped, such as water, oil, or other liquids. The motor or driver that drives the pump is mounted above ground level, while the pump assembly, consisting of impellers and shaft, is submerged beneath the liquid.

2. The shaft is connected to the motor or driver on top. This shaft rotates and has multiple impellers mounted on the shaft. The impeller blades are curved. As the shaft rotates, the impellers also rotate, creating kinetic energy within the surrounding liquid.

3. The bottom of the pump assembly has openings that allow liquid to enter the pump. The rotation of the impeller creates a low pressure near the impeller tip, which draws the surrounding liquid into the pump through these openings.

4. As liquid enters the impeller, the speed increases due to the impeller's rotation. Mechanical energy from the motor or driver is converted into hydraulic energy, which increases the pressure in the liquid.

5. Vertical turbine pumps have multiple parts, consisting of a series of rotors arranged in a row. Each of these pumps increases the pressure in the liquid. As the liquid passes through these rotors, the pressure increases gradually until it reaches a higher pressure at the pump's end.

6. After the liquid passes through all the above-mentioned sections, it is sent to a storage tank, distribution system, or other process equipment, depending on the application.

7. Vertical turbine pumps are known for their efficiency and reliability. They are used in a wide variety of applications, including deep well pumping, water supply, irrigation, oil and gas production, and other industrial processes.

Disadvantages of Vertical Turbine Pump

1. Installation is relatively difficult and complex.

Vertical turbine pump installation requires careful planning and expertise. Vertical installation requires careful attention to alignment, structural design, and seal management. Everything must be precise to avoid vibration problems or incorrect installation positions, which can affect the efficiency and life of the pump.

2. Pumping Limitations

The submerged impeller of a vertical turbine pump requires a positive suction head to operate properly. In some cases, suction head limitations (or NPSHa) can limit pump operation at certain depths.

3. Corrosion

Since vertical turbine pumps are exposed to highly corrosive liquids, installing the pump can cause corrosion in the submerged parts. This may require complex designs and corrosion-resistant materials.

4. Maintenance

Maintenance of the submerged components of a vertical turbine pump is relatively difficult. Special equipment or maintenance procedures are required, especially for installations in deep wells. Although this type of pump requires less maintenance than other types of pumps and is difficult to install, maintenance is still required.

5. High Cost

Vertical turbine pumps can be more expensive than other types of pump systems, depending on the equipment, materials, and construction, as well as installation requirements such as depth, flow rate, and materials used, which affect the cost of the equipment and maintenance.
