From single-component rebuilds to full system overhauls — our network handles every major marine desalination brand at slip-side, dry-storage, or shipyard.
Worn pistons, seals, or check valves. Most often presents as pressure that climbs slowly, fluctuates, or won't hold under load.
Salinity creeps above spec. Cleaning may recover performance — if not, membrane replacement is required.
Reduced feed flow, frequent filter changes. Common after coastal plankton blooms or marina silting.
Cavitation noise, vacuum spikes on the feed side, or failure to prime. Often impeller wear or air intrusion.
Phantom error codes, false high-salinity alarms, system shutdowns. Salt corrosion is the usual cause.
On Spectra Clark Pump and similar systems, reduced efficiency or oscillation indicates internal wear.
A few checks you can do dockside before booking a technician. They often shorten the repair — and sometimes solve it outright.
Check the sea strainer and pre-filters first — clogged filtration accounts for the majority of false alarms.
Watch the high-pressure gauge during a fresh-water flush. Spikes or instability point to pump or pressure-relief issues.
Sample the product water with a calibrated TDS meter. Persistent readings above 500 ppm usually mean a membrane or seal issue.
Log run-hours since last membrane swap. Most installations want a swap or pickling between 2,500–4,000 hours.
If you smell anything in the product water, stop using it and book service immediately — likely a fouled carbon block or microbial growth.
