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.

Spring energized valve stem packing contributes to the overall performance of industrial operations. They serve the vital task of keeping oil and liquids in while keeping contaminants out.

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

Rod seals are static seals installed in glands or housings to prevent the leakage of fluid from within a cylinder to the outside as the rod cycles.

JST's Packer elements are flexible elastomeric components that are used to seal between the outside diameter of the production tubing and the casing, liner or wellbore.

The water pump seal D1 is composed of one or couple of fabric reinforced Chevron V rings (DM), back up ring (DD) and header ring (DS) for plunger sealing.

The function of a hydraulic wear ring is to guide the piston and piston rod of a hydraulic cylinder, absorbing transverse forces. At the same time, it prevents metal-to-metal contact, optimizing the performance of the sealing system.
