cylinder liner zirconia ceramic for mud pump  

Features:

1.API Spec 7K standard design

2. Normal service life not less than 4000h;                    

3.High performance cost ratio;         

4.Forged 45# steel for outer sleeve.

Advantage compared to alumina:

zirconia exhibits better impact strength;
zirconia is harder than alumina;
zirconia can be honed to finer surface finishes than alumina. Finished to 4RMS, the zirconia liners provide a surface finish that is three to four times finer than alumina.

All three of these property advantages translate to lower ownership costs. The improved wear directly extend the service life of the sleeve, while the improved impact strength reduces significantly the costs of replacing broken liners in the field. The surface finish improvements, meanwhile, have an indirect effect. The finer surface finish means less friction with the elastomer-and-metal pump pistons, which in turn extends piston life and reduces pump-cooling requirements.
