Vertical turbine pumps are one of the most commonly used deep well pumps. They are used in a wide range of applications like processing water in industries, in cooling towers at power plants, for pumping water to fields for irrigational uses, and more. Yet, not many are aware of the incredible features and working capacity of these pumps.
As one of the top vertical sump manufacturers in India, Sintech is here to guide you through the working principle of these pumps and how to select the right vertical pumps that best fit your application requirements.
What is a vertical turbine pump?
A vertical turbine pump is a sub-category of centrifugal pumps. These pumps are specifically designed to pump water from deep reservoirs and underground borewells. They are also known as shaft turbopumps, sump pumps, or deep good turbopumps.
These pumps are connected to the ground-level motor via a long vertical axis, hence the name vertical turbine pumps. It transports fluid/water from deep groundwater reservoirs to the ground level.
Vertical turbine pumps are used in a wide range of industrial environments and are time-tested pumps. The efficiency and easy maintenance of these pumps make them a great choice for various industrial requirements. These pumps are primarily used in the chemical processing, petrochemical, power generation, oil and gas exploration, mining, and seawater desalination industries.
How do Vertical Turbine Pumps Work? The Working Principle
Vertical Turbine pumps move in a specific direction and cause the gas molecules to collide with moving solid surfaces. These pumps have a rapidly rotating fan that hits gas molecules and blows them from the inlet towards the outlet. This action causes a vacuum-like state inside the pump chamber.
Most vertical turbine pumps have multiple stages. Each stage has two blades: a rotor blade that rotates at high speeds and a stator blade. When a gas molecule enters the pump inlet, it hits the rotor blade. This mechanical action of the blade transfers kinetic energy to the gas molecule. The gas molecule hits the surface of the rotor again and moves towards the exit.
Structure of Vertical Turbine Pumps
Vertical turbine pumps are designed with both open and closed impellers. The bearings in the diffuser bowl are lubricated by the transferred liquid. At the top of the pump, a high-thrust motor is mounted and a spindle bearing is located at the bottom for product lubrication.
Typically, vertical turbine pumps are run using AC motors or diesel engines. The end of the pump contains a rotating impeller that is attached to the shaft. The pumped water is directed into a housing known as the bowl.
Multi-stage vertical turbine pumps contain multiple impellers mounted on the same shaft. A multi-stage pump produces higher pressure that makes it easy to transfer water from deep beneath the ground to the surface level.
Precautions to Take while Operating Vertical Turbine Pumps
Just like any other pump, it’s highly recommended that you follow pump manufacturer instructions for the best results. Get in touch with leading vertical sump pump suppliers in India for pump operation guidelines. Make sure that the pump operates within the optimal and permissible operating ranges as mentioned by the pump manufacturer.
Here are a few precautions to take before operating the pump
Before installing the pump, make sure to check the driving power and speed. You can find these numbers printed along with the pump serial number on the pump nameplate.
Make sure that the oil pan is deep enough to match the pump’s length so that there is no interference.
Clean the pipelines before installing the pump.
Check if all loose objects are well connected. Tighten bearings and seals properly.
Make sure to follow the installation procedure specified by the pump manufacturer.
Tips to Buy Vertical Pumps
Step 1 – Calculate the Flow Rate
You need to specify several factors like – the purpose of the pump, work environment, expected output to your chosen vertical sump pump manufacturer in India. Calculating the desired flow rate is a good starting point. The flow rate is generally measured in lpm (litres per minute) or gpm (gallons per minute).
Step 2 – Calculate the Required Number of Heads
The total number of heads is determined by the total pressure required for the pump to do its job i.e., raise the water/liquid to a specific height.
Step 3 – Describe the liquid to be Pumped
Here are a few questions to ask here:
Will the pump transfer fluid or oil? Will it handle something more viscous? Pumps that handle viscous chemicals require materials that are strong and durable.
What is the temperature of the pumped fluid?
Does the fluid contain suspended solids? Are the solids fragile – easy to be broken or are they stringy?
Step 4 – How will the pump be powered?
The final step to consider is how to power the pump. Will the pump be powered by a stand-alone motor? And so on.
