Premium's zirconia liner offers life time cost savings, significantly longer service, better performance and safer operation than those made of more commonly used alumina ceramic. Premium's zirconia liner is a proprietary Zirconium-based matrix that has significantly improved mechanical characteristics. Mud Pump Zirconia Liners GARDNER DENVER PZ-7, PZ-8, PZ-9, PZ-10, PZ-11
◎ Zirconia has three important property advantages 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 4 RMS,
◎Zirconia liners - provide a surface finish that's 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 cuts down on the significant costs of replacing broken liners in the field. The surface finish improvements, meanwhile, have an indirect effect. Mud Pump Zirconia Liners GARDNER DENVER PZ-7, PZ-8, PZ-9, PZ-10, PZ-11

What is Zirconia?
• Its great hardness, low reactivity, and high melting point have made it the oldest mineral that can be found on earth.
• Zirconium Dioxide (ZrO 2 ), also known as zirconia is a white crystalline oxide of the element zirconium (Zr).
• Exists naturally as the mineral Baddeleyite.
• One of the most studied ceramic materials.
Zirconia Case Study
→ Conducted four year case study and collected over 12,000 pumping hours
→ Pumps using Chromium Liners had expendable cost of $47,000 vs. $11,000 for Zirconia Liners
→Pump shutdowns were 4x higher (8 vs. 32) in chromium pumps compared to Zirconia
→ Zirconia lined pumps used approximately 1/5 of the pistons compared to chromium lined pumps
Zirconia Benefits
Mud Pump Zirconia Liners GARDNER DENVER PZ-7, PZ-8, PZ-9, PZ-10, PZ-11
→ Ceramic Liners out perform steel Liners
→ Zirconia is significantly stronger and tougher than Alumina in bending or tension, often by a factor of 4 or more
→ Does not require self aligning piston rods
→ Extended Life and less wear reduces overall expendable cost
→ Traditional liner hourly cost is approximately $1.05 per hour, while Zirconia Liners are approximately $.23 per Hour
