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.

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.  

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.

BS seal is rod seal for hydraulic cylinders, single-acting, polyurethane u-cup design with secondary sealing lip.

The ID S seal is used for wellheads, downhole tools and surface pressure control equipment as a critial part.

A glass filled nylon wear ring, also called wear band, offers high bearing load capacity over a broad range of temperatures.

SPGW is a high performance, double acting compact piston seal, to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
