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.
JST FHP series is made of a helical wound spring and a polymer jacket, which is mainly used for piston.
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.
JST's centralizer rubber fins is made according to customer requirements. The centralizer fin has a retrievable, reseatable, flexible design. This Rubber and metal reinforced rubber centralizer fins are available for a variety of MWD (measurement while drilling) tools and oil well logging and monitoring instruments.
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.
Hammer union seals are used for hammer joint type pipe connections to establish flow lines and prevent leakage.
Rotary shaft seals with PTFE ring have been specially developed for use in harsh conditions. They are used when shaft seals with classic elastomer lips reach their performance limits.
