Well service plunger pump packing


In order to eliminate extrusion and provide excellent wear resistance for fracturing, acidizing and cementing pumps, JST has developed high performance well service pump packings; It provides maximum sealing for high-pressure oil well service pump.


JST manufactures well service pump packings in a wide variety of materials to suit specific well conditions and operating parameters, they are available in a wide range of elastomeric materials and high performance resins, including NBR, HNBR, FKM, filled PTFE, fabric reinforced rubber.  to suit specific well conditions, operating parameters, and fracturing fluids like the below applications:

Used in various fracturing and cementing applications.

Used where high pressure, chemical fracturing and carbon dioxide are present.

Used for extreme performance under high pressure and where abrasive proppant is required.


The well service pump packing are used in rod glands to seal the extension rods which force fluid through the pump in positive displacement pump applications (also known as plunger pumps).  Sealing of the extension rods is critical in order to maintain system pressure.  In addition to pressure retention, well service packing must keep the pump’s hydraulic fluid and pumping media separated.  

They are manufactured with superior quality and workmanship to provide exceptional sealing.  JST produces complete packing assemblies -- header ring, pressure ring and female adapters -- as well as custom machined lantern rings and spacers.  

Advantages:

1.More cost-effective 
2.Suitable for various well conditions
3.Standard and custom sizes are available
4.Longevity of service life
