What are the requirements for the medium in cavitation margin experiments?

The required net positive suction head of a pump is an inherent property; centrifugal pump manufacturers use water for testing, with no specific requirements regarding the medium used. Generally, high inlet pressure and low temperatures (below -40°C) are recommended as conditions for simulation tests, in order to ensure that the pump can maintain axial force balance and withstand low temperatures
