API Tubing pump
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.To achieve maximum performance,API subsurface pumps are machined with extra small clearance between the plunger and the inside wall of the barrel.Our sucker rod pumps are categorized according to the API 11AX pump designation.
API Rod PumpsSucker rod pumps, also known as sucker rod pumps or insert pumps, are classified by the letter R.RH Rod PumpHeavy-wall barrel subsurface pumps for use at greater depths or under harsh pumping conditions, such as scale formation.RHA PumpRH insert pump with stationary barrel and top anchor seating.Available with either a cup seating assembly (RHAC) or metal seal (RHAM).Field of applicationWells of moderate depth and wells with scale formationSandy wellsLow fluid-level gaseous or foamy wellsRHB PumpRH insert pump with stationary barrel and bottom anchor seating.Available with either a cup seating assembly (RHBC) or metal seal (RHBM).Field of applicationDeep wellsWells with low static fluid levelsRHT PumpRH insert pump with traveling barrel and bottom anchor seating.Available with either a cup seating assembly (RHTC) or metal seal (RHTM).Field of applicationWells that are pumped intermittentlySandy wellsRW Rod PumpThin-wall barrel sucker rod pumps for use in wells of moderate depth and large volume wells.RWA PumpRW insert pump with stationary barrel and top anchor seating.Available with either a cup seating assembly (RWAC) or metal seal (RWAM).Field of applicationLarge volume wellsSandy wellsLow fluid-level gaseous or foamy wellsRWB PumpRW sucker rod pump with stationary barrel and bottom anchor seating.Available with either a cup seating assembly (RWBC) or metal seal (RWBM).Field of applicationLarge volume wellsSuitable for deeper wells due to bottom anchor designWells with low static fluid levelRWT PumpRW insert pump with traveling barrel and bottom anchor seating.Available with either a cup seating assembly (RWTC) or metal seal (RWTM).Field of applicationLarge volume wellsWells that are pumped intermittentlyRX Rod PumpRod pumps with heavy wall, internally threaded barrel.RXB PumpRX rod pump with static barrel and bottom anchor seating.Available with either a cup seating assembly (RXBC) or metal seal (RXBM).Field of applicationSuitable for greater seating depths than RHB pumpsAPI Tubing PumpsTubing pumps are classified by the letter T.TH pumpTH 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 applicationSuitable 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.
