Hydraulic Power Systems

Links:

Harken hydraulic power units are the complete package and can power functions ranging from winches and backstay cylinders to keels and windlasses. They can include optional prewired labeled control boxes or act as standalones, central, or supplemental units. Harken power units come with 4000 watt 24V DC motors. 12V DC motors and valves are available by special order. Contact Harken for lead time and pricing.

High-Strength, Corrosion-Resistant Materials

Coated aluminum tanks have Hardkote-anodized 6061-T6 aluminum top plates. Manifolds are made with clear-anodized aluminum.

Units come with a prewired control box made of tough polycarbonate for motor and valve controls. The terminals and valve wire sets are all sealed and labeled—just connect the functions you need.

High-Efficiency, Low-Maintenance Designs

Run up to 13 functions and 3 simultaneous functions at full power.

Use the built-in, double-flow function to supply more oil to power-intensive equipment.

Tank-mounted electrical motor contactors meet the IP67 waterproof specification.

Fan-cooled, series-wound motors are energy-efficient at all speeds.

Manifolds and pumps are preplumbed, saving space, installation time, and additional hardware.

Drop-in return line filters with status gauges provide a no-mess alternative to typical spin-on styles.

HYDRO HP POWER UNIT

The Hydro HP includes a motor with pump that has high pressure output to 5000 psi at 2.5 L/min. It can link to either a manual or electric system for push-button cylinder operation. The Hydro HP includes a motor contactor but no switches. The same control boxes can be used.

Pressure Booster Manifold

The pressure booster manifold is an optional addition for large powered systems with multiple cylinders that carry low system pressure. The manifold features an integrated pressure intensifier that multiplies low inlet pressure to an efficient 5000 psi. By increasing pressure, smaller cylinders can carry a higher load, saving weight and reducing cost.

Features include: 5000 psi factory-set pressure relief, built-in filter, analog pressure gauge, electric on-off switch, and a manual override. Anodized-aluminum box comes in 2.5 L/min and 5 L/min sizes.
