What is the pressure of a condensate pump?
20 psig pressure
Most stock units will come with their pumps set to discharge at 20 psig pressure. That’s because the pump has to discharge at 5 psi higher than the pressure at which the boiler is operating. Low-pressure steam boilers operate up to 15 psi, so that’s why the condensate pump is capable of discharging at 20 psi.
