HYDRAULIC STEERING SYSTEMS

for commercial craft MT 230 - MT 345 - MT 455 - MT 600 - MT 900 and MT 1200

Available for single and dual station control. Cylinder and pump can be supplied separately. Please see selection table for determination of steering wheel revolutions. Axial plunger pumps with 7 plungers

Stainless steel steering wheel shaft, extra strong for large marine steering wheels These steering systems are supplied complete with fittings for hydraulic tubes The cylinders are provided with bleed nipples which accept a quick-release coupling for rapid bleeding. The piston rod is made of stainless steel

The cylinder is provided with a base plate with universal joint and a swivelling rod end, so that alignment mistakes can be absorbed.

These pump units and cylinders are fully interchangeable, thus enabling the builder and the owner to choose the best possible combination of price and number of steering wheel revolutions.

The smaller the pump unit, the lower the price, but also: the higher the number of revolutions. The rudder torque always determines which cylinder is to be selected.
