We offer three types of tubing pumps: THD pumps, THC pumps, and THM pumps. The standing valve of THC or THM pump can be secured and sealed by either a mechanical or cup hold-down. The plunger and standing valve can be removed together for routine pump inspection while keeping the tubing intact, making these pumps ideal for wells requiring frequent maintenance.
Our subsurface sucker rod pumps are manufactured in compliance with API 11AX standards and carry both API monogram and ISO 9001 certification. The technology was originally introduced from the USA in the 1980s. We provide over 40 models and sizes with diameters ranging from 28 mm to 108 mm.
