Centrifugal pump speed is too high, the method of controlling the cavitation margin with the external pipeline, the pump's own performance, the centrifugal pump speed is too high to effectively reduce must cavitation margin, if the external pipeline self-priming height design requirements, the safety factor of the cavitation margin is too small, then easy to produce cavitation.
Rubber rotor pumps are the better solution to cavitation problems!
Material: Rubber lobe pump with rubber covered rotor, with corrosion resistant chemical properties.
Low speed: The rubber lobe pump uses an external speed reducer to control the speed from 10-650rpm. Taking into account external factors such as suction range, temperature and piping design, the rubber lobe pump will control the speed within a reasonable range to reduce the NPSHr as much as possible.
Strong self- priming: rubber lobe pumps can be considered in the petroleum and petrochemical industry up to 9 m self-priming, petrol and diesel pumping.
