A smooth power curve, not easy to have a super power, but this type of impeller cavitation performance than ordinary closed impeller, especially suitable for use in the pump pressure on imports.

Super-cavitation is created when gas bubbles are intentionally vented along all or part of an object travelling underwater so as to reduce the drag caused by a wetted surface.

Conductive PE bag is made from LDPE, anti-cavitation agent and super conductive carbon black after blow molded by special machineries.
