Oilfield Corrosion Resistant Sucker Rod Pump with 1.2-9.0ft Stroke Length and 31.75-57.15mm Diameter for Deep Well Applications
Heavy wall and thin wall sucker rod pumps feature seating nipple connections on the tubing string, installed down to the well bottom. The plunger assembly connects to the sucker rod string, with the pump fixed inside the seating nipple. The plunger assembly moves up and down in reciprocating motion to achieve pumping operations.
If pump quality issues occur, the entire pump can be retrieved through the sucker rod string without removing the tubing string, significantly simplifying maintenance operations.
