API THBC PUMP/ Precision API Tubing Pump with Heavy-wall Barrel

The THBC pump is a precision API tubing pump with a heavy wall barrel and cup  type bottom hold-down. The hold-down is located on a retrievable standing valve assembly. This type of tubing pump works best for wells expected to produce large volumes of fluid

The B-13 TH barrel has a maximum wall thickness of 0.250", is externally threaded, and has an inside diameter tolerance of minus 0.000" to plus 0.002" from nominal bore size. The THBC Pump can be assembled with numerous types of plungers and components to suit your well’s environment.

features:

• Large fluid flow areas through standing and traveling valves make TH type pumps perfect for producing heavy, viscous fluid.

• Stronger construction since heavy wall barrel connects directly to tubing string and sucker rod string connects directly to top plunger cage of traveling assembly.

• Available in 1.75", 2.25", and 2.75" for 2 3/8", 2 7/8", and 3 1/2" tubing.
