Maximum pressure (bar) 345 bar

Maximum pressure (psi) 5000 psi

Harken offers 1-, 2-, and 3-speed pumps for hydraulic systems. Our 2- and 3-speed pumps deliver oil when the handle is pushed and pulled, delivering oil faster and more efficiently 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 on 1- and 2-speed pumps is factory-set to a maximum of 5000 psi. Mounting patterns for all pumps are identical, making upgrades easy. Bolt holes in the hardcoat-anodized 6061-T6 aluminum pump housing are threaded with stainless steel inserts to prevent corrosion around the stainless bolts. An optional adhered isolation plate improves load distribution even more by transferring torque directly to the mounting surface rather than the bolt holes. Piston shafts and rocker arms are machined from 17-4PH stainless steel. 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.
