Introduction
Sealable penetrations
into ECB provided for
deck switch wiring.
Plumbing to manifolds is
under reservoir top so there
is no exposed plumbing
(not visible).
Harken Hydraulic Power Units (HPU) are the complete power solution. Offered in three sizes (Hydro 1, 2 and 3), the HPU can power
functions including winches, furlers, sail trim cylinders, windlasses and keel cylinders. HPUs can include waterproof, prewired electronic
control boxes (ECB) or act as stand–alone, central or supplemental power units.
Harken HPU features a 4kW 24VDC motor which is sized alongside the pump to power a single function. With additional pumps and
motors, multiple functions can run simultaneously, or the built-in double-flow feature can supply more oil to power-intensive functions.
Motors are fan-cooled, series-wound and energy-efficient at all speeds.
Factory-installed manifolds and pumps are internally plumbed, saving space, installation time and additional hardware. Valve manifolds
are equipped with horizontal ports to provide ease with hose routing. Elevated reservoir fill cap keeps oil from spilling, filters air
exchange and removes moisture from the tank to ensure a healthy hydraulic power unit. Drop-in return line filters with status gauge
make maintenance fast and easy.
The prewired ECB features sealed passage for switch and valve wires. The ECB is prewired internally and contacts are labeled. The user
is required to make electrical connections for supply power, switches and valves.
Prewired and waterproofed
control boxes are molded
from extremely tough
polycarbonate.
Coated aluminum tanks have
hardcoat-anodized 6061-T6
aluminum top plates. Manifolds are
made with clear-anodized aluminum.
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.
