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.

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.
Lockdown screw seal is used mainly in geothermal applications, HNBR packing with stainless steel caps provide superior performance over metal pressure seals.
JST's metal end cap seal is elastomer bonded onto 2 steel caps. This provides high level of extrusion resistance.
A seal assembly for use in a wellbore tool, it acts as a flow restrictor protecting a lower end of the seal assembly from high pressure and/or high volume flow.
The oil scraper ring is a part located at the rear of the pump packing seal.
V Packing consist of multiple male and female adaptor, usually a group of three to seven v rings, used for low or high pressure applications with Single or Double acting cylinder.
PDR rotary shaft seal extends the boundaries of elastomeric radial shaft seals, utilizing advanced materials and design techniques to provide optimal sealing performance for each application. The result is a superior sealing solution that retains a compact sealed casing.
