INNOVACERA's ZTA ceramic composite pump cylinder liner is a core wear resistant component for the hydraulic end of the pump, specifically designed for extreme working conditions such as oil drilling and shale gas fracturing. The ceramic pump liner adopts an advanced "metal shell + ZTA (zirconia reinforced alumina) ceramic liner" composite structure, perfectly combining the high toughness of metal with the extremely high hardness of ceramics. Compared to traditional dual metal cylinder liners, its wear resistance and corrosion resistance have been significantly improved, which can greatly extend the service life of the equipment in high-pressure and high-sand-containing mud environments. At the same time, the micro scale precision inner hole processing effectively protects the piston seal, making it an ideal choice for helping drilling engineering reduce costs, increase efficiency and improve operation efficiency.
