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 centralizer rubber fins is made according to customer requirements. The centralizer fin has a retrievable, reseatable, flexible design.
