Hydraulic Starting Solution Brochure EN

The Technology that turns engine faster. With over 90% efficiency Hydrotors cranks any engine size, from very small up to over 70litres displacement. With various flanges, configurations pre-engage and soft cycle inertia starters, with a overhung pinion version, the Hydraulic starter can be fitted on any engine. 

If no ring gear is available, starting over a PTO is also possible. Hydraulic Starters combine the high efficiency of the axial piston motor concept which provides high torque at any temperature or environment. Together with the soft engagement Valve Hydraulic starting guaranties a minimum wear of the engine ring gear and the pinion.

EPS - Engine driven pump supported recharging system

All HPS systems can be complemented with a special engine driven pump, either by belt or gear. Flanged versions are available. As soon as the engine runs, it starts to recharge the accumulator. This HYDROTOR pump incorporates an internal unloading valve, which switches the pump to idling mode, as soon as the max. adjusted pressure is reached. No more force is required for rotation. It will automatically cut in again, when the accumulator pressure falls below a certain value.
