and marine grade materials.
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
