Abstract

The invention relates to a method for priming of a pump (1) in response to a priming condition, wherein the priming comprises the steps of:- confirming that the liquid level in the reservoir (20) is located at the same level or above the upper portion of the impeller (8),- driving the impeller (8) in a reverse direction of rotation, wherein the duration of the reverse operation of the impeller (8) is equal to or more than 2 seconds and equal to or less than 5 seconds,- stopping the impeller (8) from rotating in the reverse direction of rotation,- driving the impeller (8) in a forward direction of rotation,- detecting, during the forward operation of the impeller (8), whether too much gas is present in the volute (10), and- in response to detection of too much gas in the volute (10), stopping the impeller (8) from rotating in the forward direction of rotation and returning to the step of driving the impeller (8) in the reverse direction of rotation, and in response to non-detection of too much gas in the volute (10), exiting the priming of the pump (1).
