Zirconia liners offer lifetime cost savings, significantly longer service, better performance, and safer operation than those made of more commonly used alumina ceramic. Zirconia has three important property advantages compared to alumina:
- Exhibits better impact strength
- Is harder than alumina.
- Can be honed to finer surface finishes than alumina. Finished to 4 RMS, 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 extends the service life of the sleeve, while the improved impact strength reduces significantly the cost 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.
- Reduced liner and piston wear.
- Increased impact characteristics.
- Lower thermal load on the liner wash systems.
- Higher thermal ratings.
- HP design with the shoulder on the hull to prevent sleeve slippage.
- ID tolerances of +.010” / -.000”.
- The surface finish of 4-8 RMS.
- Hardness is HV 0.3 Kg/mm – 1100/1200 (92-94 Rc).
- Improved performance for high-temperature applications.
- Liner Sizes are available from 4” to 8” for all popular mud pumps.
