Downhole Pump and Parts

The tubing pumps can be sunk into wells in sequence as follows: barrel is run down to the setting depth on the tubing and then plunger with the standing valve on the rod string. For tubing of same diameter, tubing pumps are always of larger capacity than insert pumps. The tubing pump is simple in structure and applicable for wells not too deep and of higher production rate.

Tubing pumps are classified as THM and THC 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 integrallyfor normal pump check, with the tubing remain intact. This makes the tubing pumps suitable for wells usuallywith short pump check intervals.
