Gentlemen, does anyone know anything about the flushing procedures for the secondary seal of hot oil pumps, the steps involved in putting it into use, and what the purpose of flushing the secondary seal is? Urgent need, thank you all
You are referring to the double-end face seal solutions 52 and 53, right? In terms of principle, one of them operates under pressure-free conditions while the other operates under pressure; their function is to provide buffering or isolation, as well as to improve the working conditions of the mechanical seal and enhance its sealing reliability. Before starting the pump, it is necessary to preheat the pump, and the mechanical seal flushing system should be activated first. Only after confirming that the system is functioning properly should the temperature be increased. The pump should be stopped for maintenance only after its temperature has dropped; of course, the flushing system should remain active throughout the standby period
