Abstract
A pump system for pumping liquid from a well into a pipe is disclosed. The pump system comprises: a suction cavity in fluid communication with the well via an inlet port controlled by an inlet port valve, a plunger, reciprocally movable within the suction cavity, and a delivery conduit. The delivery conduit is in fluid communication with the pipe via an outlet port, and with the suction cavity via a connection port controlled by a connection port valve. The pump system also comprises a tubular encapsulation, encapsulating the suction cavity, the plunger, the delivery conduit and the valves.
