Mobile vehicles, both tracked and wheeled, are often used to refuel/unload stationary tanks. In this case, the unsteady mode of operation of such centrifugal pumps is often observed. A constant change of operation conditions, in particular the static component of the pump head, leads to a change in its operating mode, as a result of which most of the time the pump operates in off-design mode. A methodology has been developed for determining the actual pump efficiency for a tank filling-draining cycle with two variable parameters: the distance from the level of the pumped fluid in the well to the bottom of the tank (to the on float) and the tank height (or the distance between on and off floats).
