Subsurface Sucker Rod Pumps Thin Walled Rod Insert Pump With Chrome Plated Coating

API Rod Pumps
Sucker rod pumps, also known as sucker rod pumps or insert pumps, are classified by the letter R.
RH Rod Pump
Heavy-wall barrel subsurface pumps for use at greater depths or under harsh pumping conditions, such as scale formation.
RHA Pump
RH insert pump with stationary barrel and top anchor seating.
Available with either a cup seating assembly (RHAC) or metal seal (RHAM).
Field of application
Wells of moderate depth and wells with scale formation
Sandy wells
Low fluid-level gaseous or foamy wells
RHB Pump
RH insert pump with stationary barrel and bottom anchor seating.
Available with either a cup seating assembly (RHBC) or metal seal (RHBM).
Field of application
Deep wells
Wells with low static fluid levels
RHT Pump
RH insert pump with traveling barrel and bottom anchor seating.
Available with either a cup seating assembly (RHTC) or metal seal (RHTM).
Field of application
Wells that are pumped intermittently
Sandy wells
RW Rod Pump
Thin-wall barrel sucker rod pumps for use in wells of moderate depth and large volume wells.
RWA Pump
RW insert pump with stationary barrel and top anchor seating.
Available with either a cup seating assembly (RWAC) or metal seal (RWAM).
Field of application
Large volume wells
Sandy wells
Low fluid-level gaseous or foamy wells
RWB Pump
RW sucker rod pump with stationary barrel and bottom anchor seating.
Available with either a cup seating assembly (RWBC) or metal seal (RWBM).
Field of application
Large volume wells
Suitable for deeper wells due to bottom anchor design
Wells with low static fluid level
RWT Pump
RW insert pump with traveling barrel and bottom anchor seating.
Available with either a cup seating assembly (RWTC) or metal seal (RWTM).
Field of application
Large volume wells
Wells that are pumped intermittently
RX Rod Pump
Rod pumps with heavy wall, internally threaded barrel.
RXB Pump
RX rod pump with static barrel and bottom anchor seating.
Available with either a cup seating assembly (RXBC) or metal seal (RXBM).
Field of application
Suitable for greater seating depths than RHB pumps
API Tubing Pumps
Tubing pumps are classified by the letter T.
TH pump
TH is the only tubing pump configuration specified by API Spec 11AX.
Equipped with a heavy wall barrel and a bottom hold-down (anchor), these pumps are suitable for wells with harsh pumping conditions and were scale formation is a problem.
Available with either a cup seating assembly (THC) or metal seal (THM).
Field of application
Suitable for very deep wells if connected to a sufficiently robust sucker rod string.
Large volume wells where the larger production capacity outweighs the higher service costs of the pump.
