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 pump plunger sealing system is adopted in the pump, which can effectively prevent the damage caused by water leakage and prevent the pump failure caused by the plunger friction overheating.    

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.

Spring energized valve stem packing contributes to the overall performance of industrial operations. They serve the vital task of keeping oil and liquids in while keeping contaminants out.

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.

O ring is a type of seals with solid rubber material or PTFE and an O-shaped cross section.

The spring energized seal is widely used in medical equipment, which is generally composed of a corrosion resistant spring and a seal ring made of U-shaped filled PTFE/UPE material.
