A pump apparatus for removing formation fluids from a gas includes a pump body containing first and second chambers separated by a narrow axial bore, a gas vent from the first chamber, a fluid inlet port to the second chamber and a fluid discharge port from the second chamber. A hydraulic head is attached to the pump body and a displacement plunger extends from the hydraulic head through the axial bore. A hydraulic circuit attached to the head is operated by a plunger reciprocating in the axial bore. Gas is vented through a vent passage in the plunger from the second to the first chamber and then through the gas vent. A conduit with a check valve connected to the fluid discharge port discharges fluid in one direction from the second chamber to a lift tube. Alternatively, the first and second chambers are omitted and an axial bore extends the length of the pump body.
