Mud Pump Flange Piston‑Rod Sealing Box

Dezhou Yangda Petroleum Machinery Co., Ltd. focuses on manufacturing flange piston‑rod sealing box, high‑quality Petroleum machinery accessories. They are essential Mud pump parts for piston‑rod sealing systems of reciprocating compressors and oilfield mud pumps, widely used in harsh working conditions including oil‑well drilling, natural‑gas transportation, chemical hydrogenation and high‑pressure hydrogen pressurization. Flange mounting surfaces, inner sealing grooves and piston‑rod holes of the product are precisely processed by CNC precision machining, featuring high dimensional accuracy and excellent cavity coaxiality. As the main housing for sealing assemblies inside Mud pump fluid end, the sealing box can be fitted with a complete set of sealing components such as packing rings, oil‑seal rings, lock springs and guide sleeves. Installed between cylinder and frame, it guides smooth reciprocating motion of the piston rod, bears internal high‑pressure medium and provides accurate positioning cavity for sealing parts. It effectively prevents high‑pressure medium inside the cylinder from leaking along the piston rod, and avoids crank‑case lubricating oil flowing backward to contaminate process gas. Meanwhile, it protects internal transmission components of Mud pump power end and extends service life of the whole machine, serving as vital Oil drilling equipment parts for drilling operations. Made of premium carbon steel or stainless steel, our sealing boxes are reserved with vent, pressure‑relief and cooling ports for easy disassembly and maintenance. Every finished product passes pressure‑resistance test and full dimension inspection before shipment to ensure stable sealing performance under long‑term high‑pressure conditions. Dezhou Yangda Petroleum Machinery Co., Ltd. can produce custom‑made sealing boxes in various sizes according to your drawings. We supply one‑stop service of complete Mud pump parts for global buyers.
