Dezhou Yangda Petroleum Machinery Co., Ltd. produces high‑quality oil seal ring assembly, high‑performance Petroleum machinery accessories. It is a vital Mud pump parts for stuffing‑box sealing systems of reciprocating compressors and mud pumps, widely used in high‑pressure working environments such as oil‑well drilling, natural‑gas exploitation, chemical hydrogenation and hydrogen pressurization.
This assembly consists of multiple oil seal rings, support rings, springs and positioning parts. All components are precisely processed by CNC precision machining with high dimensional accuracy. As the core sealing component inside the stuffing box of Mud pump fluid end, it relies on spring pre‑tension to make seal rings closely fit the piston‑rod surface and form a reliable dynamic sealing barrier. It prevents lubricating oil inside the crankcase from flowing into the cylinder, and blocks process gas from leaking into the crankcase. The bidirectional oil‑gas isolation avoids medium contami…
