Reasons why the condensate- or boiler-feed pump is

Jun 25, 2014· For instance, if you have the boiler set to operate at two psi, you'd throttle the condensate pump to discharge at seven psi. If the boiler operates above 50 psi, the pump should discharge at the boiler's operating pressure, plus ten psi. So if the boiler were in a dry cleaner's shop producing, say, 90 psi, the pump would have to discharge at 100 psi.
