Process for starting a pump intended to pump a liquid contained in a tank and to produce a substantially constant outlet pressure (setpoint pressure), according to which: 1/ the temperature (T1) of the liquid held in the tank is determined and compared to a setpoint temperature (T0); 2/ if the temperature (T1) is greater than the setpoint temperature (T0), the pump is actuated; 3/ if the temperature (T1) is less than or equal to the setpoint temperature (T0), the tank is heated for a time t1; then 4/ the pump is actuated for a time t2 during which the pump outlet pressure is measured; 5/ if this pressure is stable and in an acceptable margin of the setpoint pressure, the pump is kept going; and 6/ if this pressure is not stable and/or is not in the acceptable margin of the setpoint pressure, the pump is stopped and the tank is heated for a time t3, at the end of which steps 4 to 6 are repeated.
