The 5 1/2" Casted Mud Pump Cylinder Liner is a critical spare part for mud pumps, widely used in drilling operations. Manufactured from premium alloy cast materials, our cylinder liners offer excellent wear resistance, high strength, and long service life even under harsh drilling conditions.
This liner ensures smooth fluid delivery, reduces pump downtime, and provides reliable performance in high-pressure and high-temperature environments. It is fully interchangeable with major mud pump models (such as F-500, F-800, F-1000, etc.) and meets API 7K/ISO standards for oilfield equipment.

Key Features

API 7K Standard – Compatible with major mud pump models
High Wear Resistance – Bi-metal alloy or ceramic liners for longer service life
Multiple Sizes – 4” to 7” bore liners available
Easy Replacement – Precise fit with mud pump fluid end
Cost-effective – Reduced downtime and maintenance costs
Service Life – 800–4000+ hours (depending on type)
