    It is crucial for the steering system to perfectly suit the vessel type and its main characteristics. BCS has developed a complete line of “Heavy Duty” steering components that are designed specifically for fishing or commercial boats and thus require much higher work loads and performance. The complete range includes several models of steering helm pumps, built with materials and techniques to be extremely robust, and a wide selection of hydraulic cylinders, designed to satisfy the highest requirements of reliability and long, trouble-free service. There is also a selection of steering accessories which install easily to complete the system. These make it safe (even in severe service conditions) for the user to maintain control with the maximum steering comfort.

    A standard steering system in its basic composition just counts major elements such as:

    hydraulic helm pump(s) in case of additional control stations.
    hydraulic cylinder(s)
    rigid or flexible hoses
    auto-pilot power unit
    many types of valve or accessories

    • The working principle of the basic steering system is very simple:

      1. Turning the steering wheel in the direction desired sends an oil flow from the helm pump to the steering cylinder.
      2. This flow, which enters the cylinder, moves the piston, as well as the rod connected to the tiller arm, thus causing the rudder to rotate.
      3. Oil displaced from the opposite side of the cylinder flows back to the helm pump.
      4. To rotate the rudder in the opposite direction, simply turn the helm pump the other way.
    • The BCS helm pumps has a range of models in different displacements, as well as a variety of configurations and mounting options that allow the pump to be installed at various positions on the console.

      FEATURES

      • Compact design
      • Wide range of displacements: 20 cc – 30 cc – 35 cc – 42 ccs
      • Great variety of mounting configurations: FRONT, INTERMEDIATE, REAR and with SPORT TILT
      • Built-in lock valve to prevent any rudder feedback
      • Built-in relief valve to protect the system from overpressure
      • Cast aluminium housing for a high resistance to corrosion
      • Pump shaft with ABYC 3/4 taper
      • Easy installation
      • Built according to quality criteria and approved
      • Provided with elbow fittings and no-bleeder cap for possible additional control station.
      • NMMA Type Approved
