Spectra watermaker catalina deluxe 300 Clark Pump problem

Our spectra water maker started to leak around the cylinder > i tried to catch the situation on video. it only leaks at high pressure.
i already opened the clark pump, cleaned it from all rust and put it together again. still leaking.
does anyone know that can be sealed again? or do i have to send the pump to spectra?

Looks to me like it’s leaking from the o ring seal. Did you change these o rings or when you put it together maybe pinched the o ring .

You can get a full set of seals directly from Spectra. They will also help you diagnose the issue...which just looks like a leaking seal to me.

Having rust in your Clark pump is puzzling...there are no corrosive parts in a Clark pump. Where did the rust come from?

Re: Spectra watermaker catalina deluxe 300 Clark Pump problem

from the screws holding the pump together. the boat is new and i have no idea how long the watermaker was not in use. the membran was totally fouled (replaced it already) and beside of a few drops at the clark pump the watermaker was running just fine. first i thought the pump is leaking because of a rust track between the two clark pump parts. will try to get a new o-ring. hope it solves the problem.

Hydraulic shops or farm supply stores have o-ring material in long rolls and can make up any size if oem o-rings aren't available or you're not near a port. The material is cut and glued. Seems to last as long and any o-ring.

Re: Spectra watermaker catalina deluxe 300 Clark Pump problem

In the video you can see you have a leak at the top right where the cylinder is fitted into the block you need a new Cylinder, sorry. Once that cylinder is dislodged from the base a fraction of a mmsi there is no way to fix it. Also Those are the old o ring material, they turn brittle, crack and stop sealing well. The check valve o rings are non proprietary can find at anywhere that carries o rings, a little silicone grease goes a long way.
Corrosion forms for many reasons but one us the chemical reaction between the water and stainless and also the nickel bronze fittings. It's good to remove j tubes and high pressure tube and then fittings and clean them every so often. One speck of rust can get In and score cylinders, pistons, and annular rings.
Be careful when reassembling the cylinders/ bases to the Clark pump body, it is very very easy to dislodge the check valve o rings just a hair and have a leak.

I have the same system & also had a leak I couldn’t fix. I had a guy in Ft Lauderdale who specializes in Spectra rebuild it - cost about $250. Do you want his contact info?
