Hydraulic Reservoirs
Harken offers pressurized carbon fiber/composite reservoirs and vent-
ed blow-molded reservoirs for manual hydraulic systems. 
Pressurized Reservoirs 
All Harken pressurized reservoirs have translucent sections in the res-
ervoir walls, making it easy to monitor oil levels. Pressurized reser-
voirs 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. 
Grand-Prix Pressurized Reservoirs 
Harken offers Grand-Prix pressurized reservoirs to suit any Grand 
Prix need. They are among the lightest in existence. 
Reservoirs can be built with up to three ports on each end, customiz-
able to whatever application is required. One-way return-line check 
valves, supply-line shutoff valves, and high-quality regulators are 
available to meet specific needs. Custom sizes and configurations are 
available. Contact Harken. 
Vented Reservoirs 
Harken offers 2- and 4-liter blow-molded reservoirs for standard 
installations. Reservoirs feature a vented cap to stabilize tank pres-
sure and prevent leaks. Translucent materials allow oil levels to be 
easily monitored. 10 mm (3/8") hose barbs come standard for supply 
and return hoses.

Pump Handles
Standard round-tipped handles are made of knurled 
6061-T6 hardcoat-anodized aluminum and fit standard 
HYPM1 and HYMP2 pumps. Grand Prix versions are 
available in carbon fiber. An optional square-tipped style 
allows the handle to be rocked 5 degrees laterally from 
the pumping direction to store against the cockpit wall.
