Because there is a certain system in the cavity of the stainless steel magnetic pump and the "static bearing" is used in the magnetic pump, the stainless steel magnetic pump must not be used in the system with pressure, and both positive pressure and negative pressure are not feasible. . 1. Because the cooling and lubrication of the stainless steel magnetic pump bearing depends on the conveye...
