Harken offers 1-, 2-, and 3-speed pumps for hydraulic systems. The 2- and 3-speed pumps deliver oil when the handle is pushed and pulled, providing faster and more efficient oil delivery than other pumps. 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.
Pressure Relief: Pressure relief on 1- and 2-speed pumps is factory-set to a maximum of 5000 psi.
Mounting Compatibility: Mounting patterns for all pumps are identical, making upgrades easy.
Housing Material: The pump housing is made from hardcoat-anodized 6061-T6 aluminum.
Corrosion Resistance: Bolt holes in the housing are threaded with stainless steel inserts to prevent corrosion around the stainless bolts.
Isolation Plate: An optional adhered isolation plate improves load distribution by transferring torque directly to the mounting surface rather than the bolt holes.
Internal Components: Piston shafts and rocker arms are machined from 17-4PH stainless steel.
Shaft Design: Pumps have 7-degree splined shafts to ensure a tight fit and to allow the handle to be mounted at the sailor’s preferred angle.
