Harken's full range of cylinders are perfect for mast, sail, and keel controls. They stand up to years of high-stress use in harsh marine
environments and have proven themselves on yachts of all types-from racers to bluewater cruisers and megayachts. Their efficiency,
longevity, and reliability are evident in the selection of high-quality components, all supported by workmanship of the highest standards.
Harken offers a complete line of extremely lightweight, low-profile valves and manifolds for hydraulically-controlled systems. Harken
standard valves are half the weight of most styles, with Grand-Prix versions sculpted to further eliminate unnecessary material. An
independent pressure-relief function in each valve gives crew the ability to match hydraulic power to the maximum working load of
individual mast and sail controls. An adjustable flow control integrated into each valve fine-tunes the speed of release.
Harken offers 1-, 2-, and 3-speed pumps for hydraulic systems. Our 2- and 3-speed pumps deliver oil faster and more efficiently
than other pumps on the market. When a preset point is reached, the pump automatically shifts to the next speed. The 1-speed pump
is a simpler alternative, but features the same high-quality components as the other systems. Use 1- and 2-speed pumps for smaller
and midsize hydraulic systems; 3-speed pumps on systems with high-volume, high-pressure requirements. Pressure relief on 1- and 2-speed
pumps is factory-set to a maximum of 5000 psi. Mounting patterns for all pumps are identical, making upgrades easy.
All Harken pressurized reservoirs have translucent sections in the reservoir walls, making it easy to monitor oil levels. Pressurized
reservoirs require very little maintenance and are cleaner than those that use ambient air pressure. They can be installed in the bilge
rather than at pump level to provide a low center of gravity.
Harken offers four sizes of Grand-Prix pressurized reservoirs (20-, 17-, 13-, and 10-liter) to suit any Grand Prix need. They are among
the lightest in existence. Custom sizes and configurations are available. Contact Harken.
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. 10 mm (3/8") hose barbs are
welded to the reservoir for supply and return hoses.
Harken offers a range of hydraulic hose for high- and low-pressure oil delivery. After assembly, all high-pressure hoses are flushed clean
of contaminants before shipping.
