Duplex steam condensate return pump

Mark_5

We are bidding on replacing a leaking duplex pump & reciever tank... We can't seem to locate the original equiptment manufacturer wonder if anyone knows if they are still around ... F T Pump Inc. 139 Market St. Kennilworth , N.J. was their last known address... We're trying to replace the tank with one of a similar size to fit in the exhisting pit. It's approximately 70 gallons. Hoffman makes a cast iron unit ... which is what we prefer, but the pump configuration is different than the exhisting one. Another manufacturer has a steel tank which we're trying to avoid , although they say they make it in galvanized. We're not comfortable with the galvanized in the steam system. Do any of you have any expierence with this , & it's longevity? Mark
