The Sanjack’ Rod pump has been exported to SHELL, CHEVRON, SCHLUMBERGER, GE, NOV, JOHNCRANE, CAMERON, KBM, etc.

Annual production reaches 15,000 sets.

The type T Rod Pump has the following characteristics:

The locking device is located at the bottom. When working, the plunger is fixed and the pump barrel moves up and down.

The well fluid can be stirred continuously and the sand is not easy to deposit on the locking device to generate the card pump.

When the pumping well is stopped, the top valve ball closes the valve seat, and the sand in the oil pipe does not deposit in the pump to generate the card pump; the fixed valve and the oil discharge valve are both open valve covers, and the local resistance of the fluid is small, which is favorable for the discharge of the well liquid containing more sand.

Applicable: sand wells with viscosity below 400mPa-s

Not applicable: Due to the poor stability of the pump rod, it is not suitable to use long stroke pump and use in heavy oil wells.

Recommended for shallow operating depths,  insert pumps are thin-walled, traveling barrel, bottom hold-down pumps recognized by  as a standard design.

Whereas the plunger assembly is attached to the hold-down where it becomes stationary, the barrel assembly is the traveling portion that moves with the sucker rod string.

Because the barrel assembly moves, sand and scale can accumulate around the hold-down without sticking the pump; upon restarting operation, all settled material will be dispersed in the fluid.

The exit point for fluid is through an open three-wing cage, which prevents any solid material from reentering the pump on well shutdown and lengthens the run life of internal components.

The seating options on this pump include mechanical or cup types suitable for high temperatures, and mechanical types for simplified well maintenance.

A mechanical hold-down does not require repair unless major damage has occurred, whereas cups should be replaced every time the pump is unset. Both hold-down types follow the same procedure of setting and unsetting by placing the weight of the sucker rods down on the pump or lifting up.

RWT pumps are thin wall, travelling barrel, bottom anchor design insertable pumps.

Available with either 3 cup type hold down (RWTC) or with a mechanical lock hold down (RWTM), RWT pumps are ideal for wells with high levels of particulates due to their travelling barrel configuration, meaning less chance of the pump becoming stuck in the well.

Insertable pumps can be removed from the well without having to remove the production tubing.
