Tubing Pump

The tubing pump can be run in as follows: pump barrel is run into the setting depth along with the tubing, then connects plunger and the sucker rod, and puts them into the pump barrel. For tubing of same diameter, tubing pumps are always of larger capacity than rod pumps. The tubing pump is simple in structure and applicable for wells which is not deep and of high yield.

 Tubing pumps are classified as THD pumps and THC or THM pumps. The standing valve of THC or THM pump can be hold and sealed by a mechanical or cup hold-down. Plunger together with standing valve can be lifted out integrally for normal pump check, with the tubing remain intact. This makes the tubing pumps suitable for wells usually with short pump check intervals.
