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.
Claims19
A pump system for pumping liquid from a well into a pipe, comprising:
- a suction cavity in fluid communication with the well via an inlet port formed in a valve body of an inlet port valve and being controlled by a movable sealing member of said inlet port valve,
- a plunger, reciprocally movable within said suction cavity along an axis,
- a delivery conduit, in fluid communication with the pipe via an outlet port formed in said valve body of said inlet port valve, and with said suction cavity via a connection port controlled by a sealing member of a connection port valve;
- a tubular encapsulation, encapsulating said suction cavity, said plunger, said delivery conduit and said valves;
- wherein said outlet port is not controlled by said sealing member, wherein said inlet port is radial with respect to said valve body, and wherein said outlet port is axial with respect to said valve body.
A valve system comprising a valve body and a movable sealing member, said valve body being formed with an inlet port controlled by said sealing member, and an outlet port which is not controlled by said sealing member, wherein said inlet port is radial with respect to said valve body, wherein said outlet port is axial with respect to said valve body, and wherein said sealing member comprises a diaphragm.
