Ceramic Liner

Feature	Technical Detail	Direct Benefit for the Buyer
Service Life	Over 4000 hours (5-10x Bi-Metal)	Maximum Uptime: Dramatically reduces liner change frequency, cutting labour costs and non-productive time (NPT).
Hardness & Finish	Rockwell Hardness (HRA ≥ 91); Surface Finish 4-8 RMS	Piston Protection: Ultra-smooth finish and hardness minimize friction and wear on pistons and packing, reducing overall pump maintenance costs.
Thermal Resistance	Thermal Shock Resistance ≥ 450°C	Versatility: Ideal for geothermal and high-temperature deep drilling environments where standard liners fail.
Anti-Slippage Design	HP design with Shoulder-on-Hull	Safety & Reliability: Prevents inner sleeve separation under extreme pressure surges, maintaining pump seal integrity.
Material Flexibility	Choice of ZTA or TZP Ceramic	Customization: Select the material based on specific drilling needs (e.g., higher toughness with TZP).
