Abstract

A hydraulic pump comprises one or more outlets, one or more pressure sensors and/or one or more flow sensors linked to or incorporated in a pump's control means which is adapted to compare the or each measurement obtained from the or each pressure sensor and/or the or each flow sensor with one or more pre-set pressure or flow values stored in the memory of said control means, wherein said control means is adapted to switch off the pump once or repeatedly for a period if the or each measurement from the or each pressure sensor and/or flow sensor is outside a range of pre-set pressure or flow values, such period being sufficient for air to escape from the pump through the or each outlet or the or each pump chamber to be flooded.
