EVZ is commonly used in high-pressure mud pumps and fracturing pumps, namely Packings, the high-speed reciprocating dynamic seals. JST’S EVZ well service packing are used in rod glands to seal the extension rods which force fluid through the pump in plunger pump. 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. Its main function is to prevent plungers from leakage in high-speed reciprocating. Some special working conditions are taken into consideration when designing its structure and material, which make it apply to fracturing fluid, mud so on mediums.
JST provides high-performance well service packing, which is suitable for high-pressure and abrasive media in drilling, cementing and fracturing services. With our unique and innovative materials, the wear of plunger and fluid end is significantly reduced, therefore the well service packing can be used for long term, which reduces the pump maintenance cost. JST has patent for its well service packings.

Categories
JST manufactures well service plunger 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.
The oil scraper ring is a part located at the rear of the pump packing seal.
Wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system.
Wear rings are used to help keep the piston centered, allowing for even wear and pressure distribution on the seals. Wear rings are used in both piston and rod applications.
ODU Piston seals are work to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
Lockdown screw seal is used mainly in geothermal applications, HNBR packing with stainless steel caps provide superior performance over metal pressure seals.
The bonded seal is used in work-over and sand control operations. With the bonding of elastomer to a steel core, this serve to prevent excessive rubber compression under loading.
The water pump seal D1 is composed of one or couple of fabric reinforced Chevron V rings (DM), back up ring (DD) and header ring (DS) for plunger sealing.
