Electric fuel pump (Ducati ST2)

0

The electric pump is volumetric and has rotating lobes, with the motor immersed in the fuel. It is a brush motor energised by permanent magnets. The pump has a non-return valve which prevents emptying of the fuel circuit when the pump is not running. It also has an over-pressure valve which short-circuits the intake when the pressure exceeds 5 Bar. This prevents overheating of the electric motor.

Note. To check that this component is functioning correctly, use the "MATHESIS" tester.
