Mud Pump Liners

Premium manufactures chrome alloy sleeved liners, hardened liners, hardened / chrome plated liners and Zirconia liners. Premium also supplies genuine U.S. made rubber and urethane liner seals. All our liner products are exchangeable with OEM products and meet or exceed API-7K standards.

All our liners are made with a high strength forged steel shell machined to fit triplex pumps and fitted with high pressure lip sleeve. The liner is precision machined to exact tolerances to keep the liner concentric. The sleeve is manufactured to the bore tolerances specified by API to provide longer life by reducing gaps between the liner bore and piston.

Zirconia Liner

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.

◎ 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.

◎ HP design with shoulder-on-hull design to prevent sleeve slippage

◎ Reduced liner and piston wear

◎ Rated for all drilling operations up to 7500 PSI

◎ Bore hardness of 92-94 Rockwell

◎ ID tolerances of +.010”/ -.000”

◎ Surface finish of 4 - 8 RMS

◎ Hardness i s HV 0.3 kg/mm – 1100/1200 ( 92 - 94 Rc)

◎ High pressure design to prevent slippage

◎ Liner sizes are available from 4½” to 7” for all popular mud pump

Zirconia Liner Sleeve

Chemistry and Mechanical Properties

High Chrome Sleeve Liner

The outer hull, or body, of the liner is a high strength forging. Premium uses forgings exclusively to ensure the consistent quality. The sleeve is centrifugally cast in the Premium facilities by skilled craftsmen. It has the maximum amount of chrome for the base metal and Premium adds molybdenum to

increase the hardness depth. The sleeve is then inserted into the hull at a tightness that exceeds its counterparts. The liner is rated to match the pressure rating of the pump per liner size.

- High Strength forged steel outer hull.

· - High Chrome alloy inner sleeve honed to mirror-like finishes.

- Rated for all drilling operations up to 5,000 PSI and 7500 PSI

- Bore hardness is 62 - 69 Rockwell

- HP design to prevent inner sleeve slippage

- Extremely long service life

Chrome Plated Liner

Premium chrome plates the same outer hull in lieu of sleeve to a maximum thickness. It is then machined and polished to a mirror finish.

Features:

• Single high strength forged steel hull construction.

• Optional chrome plating to reach hardness of 62 RC. Corrosion resistance, free deformation.
