Jastram H Model Helm Pumps

The H pumps are designed to operate in “non-pressurized” hydraulic systems requiring only two lines from the helm pump to the cylinder. The Model H helm pumps include the following standard features:

• An external lockvalve to isolate with helm and prevent rudder feedback
• A pressure rating for the lockvalve of 1,875 PSI
• A powder coated, high strength cast aluminum housing which provides corrosion and abrasion resistance
• A flexible mounting pattern allowing any angle between the vertical and horizontal axis
• An internal capacity to act as a small vented oil reservoirJastram Hydraulic Power Units
