Harken offers pressurized carbon fiber/composite reservoirs and vented blow-molded reservoirs for manual hydraulic systems.
With a 20-liter version that weighs just 3.8 lb (1.74 kg), Harken’s pressurized carbon fiber/composite reservoirs are among the lightest in the existence. They are installed in the bilge rather than at pump level for a low center of gravity. Reservoirs include a one-way return line check valve and supply line shutoff valve, both with aluminum -6JIC fittings. A high-quality regulator maintains smooth and consistent oil flow.
A graduated level gauge and translucent sections in the reservoir walls make it easy to monitor oil levels. Pressurized reservoirs require very little maintenance and are cleaner than those that use ambient air pressure.
Custom sizes are available.
These 2- and 4-liter blow-molded reservoirs are used for smaller Grand Prix systems and production yachts. Reservoirs feature a vented cap to stabilize tank pressure and prevent leaks. Translucent materials allow oil levels to be easily monitored. 3/8 inch (10 mm) hose barbs are welded to the reservoir for supply and return hoses.
