Standard API Pump Types

Endurace Lift Solutions provide high quality STANDARD API PUMP TYPES:

Insert Bottom Hold Down Pumps: RWB, RXB, RHB RWB, RXB, and RHB

  • General purpose API pump.
  • Number of available accessories to meet application needs. Balanced Pressure around the barrel overcomes the disadvantages of a top anchor pump.
  • Fluid has only to pass through the anchor and standing valve to be in the producing chamber of the pump. The top anchor pump shares this advantage.


API Insert Top Hold Down Pumps: RWA, RHA

  • The top anchor (hold-down) eliminates sand settling between the pump barrel and tubing on the hold down preventing stripping jobs.
  • The top anchor pump allows the standing valve to be submerged in the fluid being pumped. This allows the fluid level to be pumped down below the seating nipple.
  • The pump barrel can act as a gas anchor in gassy installations.


API Traveling Barrel Bottom Hold Down: RWT

  • The top anchor (hold-down) eliminates sand settling between the pump barrel and tubing on the hold down preventing stripping jobs.
  • The fluid is discharged just above the hold-down, keeping solids in suspension.
  • The top anchor pump allows the standing valve to be submerged in the fluid being pumped. This allows the fluid level to be pumped down below the seating nipple.
  • The pump barrel can act as a gas anchor in gassy installations.


API Bottom Hold Down Tubing Pump: THB

  • Bore size 0.250 inches smaller than the normal tubing I.D.
  • Produces greater volume of fluid than insert rod pumps due to the large bore size
  • Large fluid flow areas through the standing and traveling valves are good for producing heavy, viscous liquid.
  • Heavy wall barrel connects directly to the tubing string.
  • Sucker rod string connects directly to the top plunger cage of the plunger assembly.
