Powersurvivor 80E parts / generic parts

[YACHT TARENTELA]

Looking for replacement membrane compatible with my Pur Powersurvivor 80 E watermaker. Can anybody give me info on what generic parts will work and where to find them? This watermaker uses 2 membranes which are the same as the single membrane used on the 40 model. I'm looking for either aftermarket membranes or a setup which uses only 1 membrane. I am also trying to find accurate water flow and pressure information for this system. Nothing in the manual or specs that I can find. Thanks, Al

This has been brought up a few times here on the cruisersforum. Being a single piston pump you need a membrane rated for around twice your rated daily output. The standard sw30-2514 membrane is your best standard match. I have a Powersurvivor 160 which uses an SW30-2521 which is rated at 300GPD. The 2514 is rated at 150GPD so should be a good match.
