Abstract

A submersible fluid pump, e.g. for supplying the actuator of a mine scraper winch, comprises at least one pair of cylinders 5a,b with pistons 2a,b adapted to reciprocate in anti-phase relationship; a non-return inlet valve 14a,b leading into each cylinder, the two inlet valves communicating with each other via a common fluid compartment 21; and a non-return outlet valve 18a,b from each cylinder, compartment 21 communicating via filter 22 with an hermetically sealed reservoir 28. A winch actuator system is described. <IMAGE>
