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.

We have been manufacturing various types of fluid end valve and seats for both frac pumps and mud pumps, covering various models for the most dominant pumps in the market.

The PTFE gate valve seat seal is made of durable teflon, it is used in rotating equipment to minimize o-ring movement.

VT type V Packing is widely used for sealing pistons and rods with both single and double acting cylinders.

Perfluoroelastomer (FFKM) O-rings have carbon fluorine bonds, making them one of the most thermally stable, oxidative stable, and chemically stable fluorinated polymers.

LNG Lip Seal For Filling Guns is commonly used in LNG (liquefied natural gas) filling guns.

In LNG operations, valves can regularly encounter temperatures below -320 F (-196 C) and pressures above 750 pounds per square inch (psi). They are also subjected to periodic variations in temperatures known as “thermal cycling,” which can result in hardware expansion as well as shrinkage and material stresses. These factors make reliable, long-term valve operation an engineering challenge.
