Condensate return pump

Where can I find a good condesate return pump ? The condensate returns to a pit and is then pumped up into the boiler. the pump must lift 9ft. and the boiler shuts off at 3 psi. We put in a high temp. 210* sump pump and it lasted less than 2 years.

    short lived pump problems

    is this for a heating system? 3 psi is much too high

    the problem may be more to do with the pump head [9ft. rise +3 psi], than the temperature.

    my 55 rad system is all gravity return, and steam gets to the rads at 3 ounces pressure.

    why don't you repipe with a gravity return, with the lowest pressure your vaporstat can handle.--nbc

    That's pretty deep

    Hoffman, Shipco, Skidmore and others all make sump-type condensate pumps but I'm not sure how deep they go. Do the returns come into the pit at 9 feet below grade?



    Post some pics if you can.

    Thankyou for the responce

    Less than 3ft. below grade. 9ft. total of vertical pipe plus 3 psi boiler pressure for about 16ft.

    Is there any reason

    the system cannot work without the pump? Do these return pipes have to handle air as well as water, or can the air be vented another way?



    If your system can operate on gravity return, as nbc says, you can simply eliminate the pump. Fewer moving parts=better reliability.
