TH pumps are heavy wall, stationary barrel, bottom anchor design tubing pumps. Available with 3 cup type hold down (THC). TH pumps give the largest possible bore size for a given tubing size, meaning the maximum amount of displacement with each stroke and therefore the greatest possible production.

THC tubing pump is a thick wall fixed barrel pump of standard design approved by international standards. They are usually used to produce wells that contain more fluid than insert sucker rod pumps can. Unlike insert pumps, the working cylinder of these pumps is part of the tubing string, which enables them to discharge more fluid than insert pumps. The press is a separate part that is usually inserted into the assembly prior to delivery at site. The travelling assembly is installed at the end of the sucker rod.
The TH tubing pumps feature heavy-walls and full-barrels.
These pumps can be assembled with:
⦁ Box-end and pin-end plungers;
⦁ Cup-type;
⦁ Tap-type or lock-type, standing-valve pullers;
All-metal, heavy-wall barrel tubing pump combines heavy-duty construction and stroke design to achieve maximum output for any given tubing size. The integral plunger eliminates the joints that are prone to failure under the working load, and carries out precision honing from end to end to ensure that the plunger has perfect holes and improve the pumping efficiency.
