Isolated Gas Compression Pump
LUFKIN Don-Nan
The Isolated Gas Compression Pump efficiently moves gas through the pump and is designed for use under a packer, preventing gas from traveling up the casing annulus.
The Don-Nan Isolated Gas Compression Pump is efficient at moving gas through the pump and is designed for pumping underneath a packer, which prevents gas from traveling up the casing annulus.
Using two plungers and two barrels enables an extremely tight plunger-to-barrel
fit throughout the assembly, resulting in precise gas transference. The extremely tight fit in this pump makes it suitable for use where little to no solids are present.
The Isolated Gas Compression Pump’s extremely rigid design extends the life of the entire rod lift system by effectively mitigating the effects of gas pound and lock. Taking the idea of a hollow valve rod a step further, this design instead uses a mercury plunger. Compared to a hollow valve rod, a mercury plunger has greater wall thickness and a thermal-sprayed coating for increased wear resistance and enhanced rigidness to eliminate buckling at the pump.
