Manufactured by Dezhou Yangda Petroleum Machinery Co., Ltd., the mud pump cylinder liner locking ring is made of high‑quality spring steel and strengthened by heat treatment. It features high toughness and stable elastic force, serving as a key limit component for Hydraulic Cylinder Assembly & Spare Parts. Used in pairs, it is fitted into the positioning groove outside Liner Assembly. It realizes axial locking positioning by its own tension to restrict axial movement and offset of cylinder liner during operation.
It buffers operating vibration, fixes the assembly position of cylinder liner and prevents components from loosening under working pressure, effectively extending the service life of the whole pump assembly. Easy for installation and disassembly, it supports fluid‑end maintenance together with Valve Parts. Cooperating with Piston & Rod Parts, it reduces seal failure risk caused by cylinder liner displacement. Combined with Seals & Fasteners, it guarantees overall assembly precision of fluid cylinder.
Dezhou Yangda Petroleum Machinery Co., Ltd. strictly controls raw materials and heat‑treatment procedures. The locking ring maintains stable elasticity and resists fracture. Complete sizes fit mainstream Mud Pump Series, and it matches complete sets of Power End Assembly & Accessories. Standard sizes are in stock, and non‑standard customization is available. Overseas oil‑field service providers and equipment distributors are welcome for inquiry. Sample test and bulk supply are available.
