Product Description

Product Description

Check valve
 A check valve is installed about two to three joints above the ESP pump to keep the tubing full liquid when the pump is off. So that, it eliminates the time it takes to raise the fluid from its static fluid level to the surface. In addition, it eliminates the protective shutdown time for fluid fallback.

Tubing Drain
 The Tubing Drain allows for the tubing string to be drained prior to tripping,
avoiding problems associated with pulling a "wet string". 

The Tubing Drain is activated by putting sucker rod to shear the shear pins
and open the large drainage ports to the annular space above the pump.
