TH pumps are heavy wall, stationary barrel, bottom anchor design tubing pumps. Available with either 3 cup type hold down (THC) or with a mechanical lock hold down (THM), 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.

TH tubing pumps are heavy-walled, stationary barrel pumps recognized as a standard design. They are often used in wells that produce more fluid than an insert rod pump can accommodate. Unlike insert pumps, the working barrel of these pumps is a section of the tubing string, which enables them to displace more fluid than insert pumps. The hold down is an independent piece that is typically inserted in the assembly prior to field delivery. The travelling assembly is installed on the end of the sucker rod string. Tubing pumps include a mechanism on the bottom end of traveling assembly to retrieve the hold down assembly should the valve require repair.

The TH tubing pumps feature heavy-walls and full-barrels.
These pumps can be assembled with:
⦁ Box-end and pin-end plungers;
⦁ Cup-type or mechanical seating assemblies;
⦁ Tap-type or lock-type, standing-valve pullers;
The all-metal, thick-wall barrel tubing pump combines heavy-duty construction and stroke design to achieve maximum output for any given tubing size. The integral plunger cylinder 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
