Does the horizontal foam pump have cavitation allowance?

When discussing the horizontal foam pump, we often pay attention to its performance and efficiency. One important parameter is the cavitation margin. So, is there any cavitation allowance for horizontal foam pump?

Firstly, we need to understand what cavitation margin is. Cavitation refers to the phenomenon of bubbles generated and flowing with the liquid due to factors such as pressure changes or pipeline resistance during liquid flow. When bubbles gather to a certain extent in the pipeline, cavitation phenomenon will form. The cavitation margin refers to the difference between the maximum cavitation pressure that can be withstood under design conditions and the working pressure of the liquid. That is to say, if the working pressure of the liquid exceeds the cavitation margin, it will lead to the occurrence of cavitation phenomenon.

For horizontal foam pump, cavitation allowance also needs to be considered. Because foam liquid has high viscosity, high corrosivity and other characteristics, it is easy to produce cavitation phenomenon in the transportation process. Therefore, when selecting the horizontal foam pump, it is necessary to determine the appropriate cavitation allowance according to the specific use conditions. Usually, we will refer to relevant standards or empirical data for selection.

In a word, whether there is cavitation allowance in horizontal foam pump is a problem to be considered. Through reasonable selection and design, the normal delivery of foam liquid can be ensured, and the service effect and life of foam pump can be improved.
