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 reservoir Jastram Model H Helm Pumps Recommended Wheel Sizes for the Model H helm pumps Photo Courtesy of Victoria Shipyard Engineered For Life At Sea MODEL min diameter max diameter H20 14” 24” H26, H36 20” 30” H58 30” 36” H60, H90, H110 36” 60” STEERING WHEEL SIZE
