The Dometic Capilano™ helm pump is a heavy duty axial piston pump specifically designed for manual steering. Every load bearing point within the helm pump runs on either a roller or ball bearing race for super low friction and smooth, positive steering. It has a built-in lock valve to prevent the steering load from feeding back to the helm. The lock valve will not allow the rudder or drive unit to move until you move the steering wheel. The valve section of the helm also includes a relief valve. This relief valve provides over-pressure protection for mechanical components and hydraulic lines. Industrial yellow baked enamel, cast alloy housing. Code Model Displacement cc cu in Relief Valve bar Relief Valve psi 294002 1250V 27.8-55.7 1.7-3.4 70 1000 294004 1275V 44.2-88.4 2.7-5.4 70 1000
