Power Unit Selection
Power unit selection must be based on the flow and pressure requirements for all hydraulic equipment that will operate at the same time.
Most Harken hydraulic equipment (winches, furlers, etc.) requires a flow of 4GPM/15 LPM, with a maximum operating pressure of
2000 PSI/140 BAR.
To select the correct power unit:
1. Consult the manual for each piece of hydraulic equipment that will be driven by the power unit. Note flow and pressure.
2. Determine which pieces of hydraulic equipment or circuits will be used at the same time (i.e. winch and furler).
3. Compare total flow/pressure required for each piece to table below to select power unit.
Harken Hydro Power Units are available in three sizes: Hydro 1, 2 and 3. Each motor/pump combination is rated at 4 GPM/15 LPM with a
maximum operating pressure of 2000 PSI/140 BAR.
