The commonality between marine water
makers is bringing sea water
up to between 800-900PSI, how they do it meaning the type of Hp pump, is what makes them different, energy recovery spectra 12v pump or brute force energy hog piston pump. Once you get past the Hp pump and some system controls, water makers are basically low pressure and high pressure plumbing
projects. So you can easily interchange a Spectra Pressure Vessel with say one of ours shown in the photo
below. I'm honestly now sure what Spectra charges for their pressure vessels, but we sell the pressure vessels for the standard Dow SW30-2521 membrane (which is what Spectra uses also) for $375. All inlet and outlet ports
are 1/4" female NPT fittings...in stock...ready to ship.
me if you have any questions:
