Oil Scraper Seal for Scrap Excess Lubricating Oil

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.

EVZ is commonly used in high-pressure mud pumps and fracturing pumps, namely Packings, the high-speed reciprocating dynamic seals.

The FDR seal is made of a helical wound spring and a polymer jacket, which is mainly used as a Flange external face seal.

The JST valve insert seal is mainly used for sealing valve seat of fracturing pump. It is made of modified polyurethane material of excellent extrusion resistance, puncture resistance and fatigue resistance, which guarantees the fracturing work under various working conditions.

T-Seal is a compact three-piece double acting seal composed of a T shaped elastomeric element and two rigid anti-extrusion rings. These compact sealing elements are designed for installation in simple O-ring grooves and are often used to modify faulty O-rings.

High-pressure Rotary shaft seals are one bidirectional rotary seal which can bear both sides of pressure and alternating pressure. It is made with slip ring and o-ring/square ring.

BT Seal is a static seal that is used to seal rough casing and tubing. It is constructed from an elastomer with anti-extrusion spring bonded within it. Springs are available in stainless steel, elastomer could be HNBR or NBR.

DLI is a dust resistance and oil-scraping double acting seal. Consist of PU and iron material.
