What is the purpose of the safety valve installed behind the manual door at the inlet of the condensate pump? To prevent backflow when the pump is operating normally, which could cause overpressure at the inlet of the standby pump Is it necessary to install one for small units? Everyone is welcome to discuss?
It’s completely unnecessary; just increase the design pressure – safety valves are wasteful and troublesome.
It’s basically useless, and it’s also troublesome to manage； Pumps that are operating properly have check valves at both the inlet and outlet, so the possibility of backflow when they are shut down is not very high.
What type of pump is this? Is it installed on the pipeline from the outlet back to the inlet?
