Due to the simplified construction, and selection of superb materials, this pump will outlast any other product on the market.
The Kobelt design eliminates the universal joint - instead the whole helm pump moves with the wheel when rotated up or down.

ULLMAN STEERING SYSTEM
The Ullman steering system for high-preformace vessels is an interface concept adapted primarily for high speeds and extreme conditions.
The Ullman Cockpit is available for single and twin outboards, single and twin stern drives.
The Ullman Rolls-Royce Cockpit System is a full fly by wire system for single and twin waterjets. |

| When a direct link from the rudder to the pedestal via a rack and pinion system isn't possible, the best, most direct and strong mechanical steering system to go for is the Jefa transmission steering system. The transmission steering is based on the same principals as the rack and pinion system; the rotation of the wheel is transferred to a push pull movement via a gearbox and levers. The difference with the rack and pinion system is that the distance from the wheel to the rudder shaft can be much bigger and the routing more complex. Via torque tubes, universal joints, and bevel gearboxes, the rotating movement is transmitted to the reduction gearbox next to the rudder shaft. The reduction gearbox transfers the rotating movement into a push and pull movement on the tiller lever. As all rotating parts are running in roller bearings, and the system can be easily back driven by the rudder, the result is a steering system which can be far away from the rudder, but with the same precision and feel as a tiller steered boat. |

Perfect for both yachts and commercial vessels; the CCO (Conversion & Change Over ) manifold is a unique and patented modern approach to hydraulic full flow-up power steering. Instead of relying on complicated and troublesome mechanical follow-up devices the CCO simply converts the oil flow into an electrical signal. This signal is transferred to an SCA amplifier,
which controls the hydraulic power units. In the event of loss of electrical power the manifolds automatically reverts back to direct manual hydraulic steering. The CCO is easy to install, safe, and simple. This makes it perfect for new construction or for retrofitting existing hydraulic FFU systems. |

HyDrive's Heavy Duty range of precision-made, hydraulic marine cylinders offer a large range of torque capacities, with strength and serviceability second-to-none. Constructed from the finest grades of bronze, brass and stainless steel, they are prefectly suited to the harsh marine environment and the punishment of heavy commercial use.
Built with safety margins far in excess of requirements, these cylinders meet all the stringent requirements of both CE and International Survey authorities. The ultra-precision of these units also allow for their use on heavy catamaran installations with fluid-link circuits.
Field replacement glands seals make maintenance possible without removal from their position. Fully articulated, the cylinders are supplied with matching rod-end bolts as well as a powerful ball-type mounting bracket. |

HYDRAULIC CYLINDERS
Our steering cylinders are in bronze and steel with stainless steel rod. The ball joint is in steel as well. The cylinder's dody is properly painted to work in a marine environment and can be in different colours on specific request. Each cylinder is supplied with brass fittings in different sizes. ACCESSORIES In the BCS products range there is a wide choice of hydraulic steering accessories, too, such as non return valves, by-passes, relief valves, steering wheels, hosing and fittings of any type and seize. Some of our standard models are shown here below. For any further reference about a great number of special configurations for the most various applications our Technical Department can supply any detail about seizes and technical data. |

| The Model 7033 outboard motor steering cylinder was designed to be attached directly onto the late model outboard motor brackets. The draglink provided is used to connect the cylinder rod onto the motor tiller arm with stainless steel shoulder bolts. |
|
| The hydraulic helms are of the axial pistons type. The helm housing is in aluminium with bronze gears and cylinder block for greater durability and longer life. The P20, P30 and P42 models are supplied with a built-in non return and relief valve. For all the other models a non return valve shall be mounted separately. The hydraulic helms are supplied without any fitting. Complete kit of fittings are available separately, which shall be specified when placing the order. The codes and descriptions of the different kits can be found on the price list. |

Reliable operation of a steering system depends upon the quality and performance of the helm pump. The Jastram "H" series manually operated helm is a precision made axial piston pump specifically designed to operate effectively at a very slow turning rate.
The H60, 90 and 110 are among the largest helm pumps made and provide excellent primary or backup steering for large steering systems. |

Being aware of the rudder position enhances safety and is of great help while docking or maneuvering. Designed for heavy-duty commercial use, the RFU 1300 is waterproof and shock resistant. It features a "contactfree" hall effect device that virtually eliminates the wear commonly experienced with potentiometers.
All the electronic circuitry necessary for a rudder feedback signal and a rudder angle indicator signal is contained within the RFU 1300. |
