Hynautic Heavy-Duty Helm Pumps—H-20 & H-40 Series

Rugged 3-line Hynautic Heavy-Duty helm pumps for commercial and pleasure boats up to 70 feet.

Hynautic Heavy Duty helms combine one or two bi-directional axial piston pumps with pilot check and make-up check valving. The result is a helm that prevents rudder feedback, is very efficient (even at low RPM), and is immediately adaptable to multi-station use. A wide choice of helm displacements and cylinder configurations make it easy to design systems for a variety of large boat performance requirements.
