1. An oil system for a turbomachine, comprising:
an oil circuit,
at least one oil-consuming piece of equipment, supplied by the oil circuit,
a pumping unit, comprising at least one speed-pilotable electrically driven pump, supplying the oil circuit, and
an electronic control unit, configured to pilot the electrically driven pump,
wherein the electronic control unit comprises two separate logics of piloting the electrically driven pump,
wherein the electronic control unit is configured to pilot the electrically driven pump according to a first logic of the two separate logics by default and to switch to a second logic of the two separate logics in case of receipt of a signal representative of a presence of a fire or of a signal representative of an overheating,
wherein, in the first logic and the second logic, a pilot speed of the electrically driven pump is non-zero, and
wherein the electronic control unit is configured to stop the electrically driven pump when receiving a leakage signal coming from a leakage detector.
