Counter-circulation shielded pump
Thread Content
Is liquid or gas discharged from the rear of the pump?
It is required that the tail pipe be connected to the gas phase area of the inlet tank; throttle orifice plates are generally installed on the counter-current piping. The back part of the pump should still be in a liquid state.
Thank you, I see. We’ve connected another pipe to the pump inlet
The reason for using a reverse circulation is to prevent vaporization, which can occur when the medium heats up inside the shielding sleeve before reaching the pump inlet. Take a look at the installation, operation, and maintenance manual.
