Well service plunger pump packing

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

The oil scraper ring is a part located at the rear of the pump packing seal.

Hammer union seals are used for hammer joint type pipe connections to establish flow lines and prevent leakage.

XTP is Double acting piston seals, composed of PTFE piston sealing ring, O-ring and X ring, and is used for the piston bidirectional seal of hydraulic cylinder. Especially suitable for separating two different mediums.

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.

The PTFE gate valve seat seal is made of durable teflon, it is compatible with the Cameron gate valve type FC, FLS, and used in rotating equipment to minimize o-ring movement.

JST's Inner and Outer BOP Seals could be made according to customer requirements. These seals are used in various type of Blow Out Preventors (BOP's).

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.
