Why are vertical turbine pumps generally not subjected to cavitation performance testing?

 Vertical turbine pumps are type of special device which helps to pumping the water on top of building. They have an unique design that enables them touse properly without interruption. Here is one interesting thing that do not consider this:  The cavitation performance of these pumps is generally not tested. But why is that?

​

Between how and they Vertical Turbine Pumps are Made

To answer this question, we need to clarify how vertical turbine pumps are constructed. Vertical turbine pumps put the motor and the spinning part, known as the impeller, below the water level, as opposed to other pumps, which rest on the ground. This keeps the impeller submerged all the time. This design vertical turbine pump allows the pump to operate quietly and smoothly with less noise.

How Vertical Turbine Pumps Prevent Cavitation

Cavitation is a problem that occurs if the water pressure drops really low, and little bubbles of vapour are formed in the water. These bubbles can burst and damage the pump. But, the impeller in vertical turbine pumps is always submerged, so they are less likely to cavitate. The water maintains the pressure even with the impeller, which prevents bubble formation.

Cavitation Testing Limitations for These Pumps

Cavitation Testing test Is not as Critical for Vertical Turbine Pumps They have already been designed to prevent cavitation. These pumps are less likely to be subjected to cavitation in real life, making cavitation tests rather meaningless.

How Vertical Turbine Pumps Are the Solution for Cavitation Issues

Design Improvements to Prevent Cavitation Issues: Vertical turbine pumps are designed to prevent cavitation issues. By keeping the impeller submerged and with relatively deep well vertical turbine pump constant pressure on its sides, these pumps can operate under the conditions which would normally cause cavitation damage. Waking up to find this sort of pump lined up for you, isn't that one of the reasons that vertical turbine pumps are the pump of choice for tall buildings or other locations where a robust, quiet pump with a small footprint is required?

Testing for Cavitation is Not Necessary

The cavitation performance of vertical turbine pumps is a non-consideration, because the impeller is always submerged. Additionally, the advantages of these pumps operating cavitation free and the inability to test for cavitation in these pumps, all contribute to the decision not to test vertical turbine pumps for cavitation performance. 

Vertical turbine pumps are unique machines that have a mixed flow vertical turbine pump distinctive design that helps to eliminate cavitation problems. The benefits of utilizing these pumps in cavitation avoidance and the limits of cavitation testing lead to the conclusion that the testing of these pumps for cavitation performance is not necessary. Vertical turbine pumps are a good example of how intelligent design can quickly solve common problems in the pumping industry, and Credo continues to focus on reliable and efficient pumping solutions.
