Electric pump

When the driver's door is opened, the Selespeed control unit receives an earth signal (dedicated line) and consequently operates the hydraulic system electric pump until a pressure of 30 bar is reached.

Whilst the engine is warming up, the pressure in the hydraulic circuit increases up to 60 bar and when the engine reaches operating temperature and the vehicle is moving the pressure stablizes at betwen 42 and 54 bar.

This gear pump is coupled to a commutator-type electric motor.

The pump is supported by a special bracket with vibration dampers and is connected to the electro-hydraulic unit by means of a high pressure pipe.
