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.

The automatic pilot and other electronic navigation systems are more popular today on every type of vessel, even smaller ones. It is possible to choose among several types of units:

• SOLENOID - VALVE POWER UNITS
• SOLENOID - VALVE POWER UNITS WITH AUTOMATIC FILLING
• REVERSIBLE POWER UNITS

For the choice of the most suitable unit it is necessary to have the steering cylinder volume, from which the actuation time is calculated and the suitable model selected.

FEATURES

• Reduced dimensions
• Great variety of models for any kind of application
• Availability of reversible and solenoid-valve Power Units
• Steering automatic filling device available on certain models for an easier and faster bleeding
• Interface with any auto-pilot
• Supplied with solenoid-valves electro-magnetically actuated
• High quality materials and components for the best reliability and performance

BCS helm pumps and steering cylinders can be combined with several accessories to complete the system and maintain safety and control. It is possible to choose among several types of relief valves, non return and by-pass valves, rudder angle indicator kits and fittings or hose kits for different configurations.
