Audited Supplier
The rod pump is composed of barrel assembly, plunger assembly, standing valve assembly and seating assembly.
Product advantages:
The maintenance operation is convenient and can be completed by lifting the sucker rod
The tubing and casing connection can be achieved by lifting the rod string, and perform well washing, steam injection, and sand washing operations.
Product limitations:
The rod pump body needs to pass through the tubing, so the oil well with the same size tubing has a smaller pump displacement.
Structure of pump
The main spare parts of subsurface sucker rod pumps are barrel, plunger and valve.
