Mechanical Top And Bottom Type Anchor Rod Inserted Pump
Mechanical top and bottom type anchor rod inserted pump description
We manufacture all subsurface pumps covered by API Spec 11AX, including all barrel and plunger materials and surface finishes.
This is why our sucker rod pumps can be furnished with the components most suitable for your field of application and pumping operations can easily be extended to corrosive environments.
API Spec. 11AX was modified to add not only new sizes and types of pumps with new quality, inspection, and tolerance requirements, but also standardized, widely used pump-component materials. Various material descriptions, their API identification symbol, surface condition, base core hardness, base material, and base-material minimum yield strength for plated barrels, are shown in Table A of Spec. 11AX. Similar tables in Spec. 11AX (B through I) are incorporated for case-hardened barrels, nonhardened barrels, balls and seats, cages, pull tubes, valve rods, fittings, seating cups, spray-metal plungers, and plated plungers. These changes have incorporated the prior information in API RP 11AR[2] and the NACE International MR 01-76[3] for materials to be used in most production environments.
RW series has the top anchor and bottom anchor type, mechanical hold-down
