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.

JST's metal end cap seal is elastomer bonded onto 2 steel caps. This provides high level of extrusion resistance.

S-Seal is designed for extreme oil and gas applications. It is a technologically advanced replacement for traditional three-piece T-Seals or O-Rings with back-ups.

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

Nylon BX R RX style Test Ring Gasket is good for valve pressure test. JST Nylon ring joint test gaskets are a no damaging method to test and re-certify ring type joint flanges.

The seal jacket of adhesive dispenser/dispensing seal is made of ultra-high molecular UHMWPE or PEEK, with installed stainless steel anti-corrosion spring with low temperature resistance treatment.

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.
