Mud Pump Valves & Seats

Premium manufactures a wide variety of valves and seats, for the following applications, among others: workover pumps; high pressure well service fracturing pumps; cementing pumps; and mud pumps.

Cross Arms/4-Web Valve & Seat

The Cross Arms Valve is a 4-Web Center Guided Valve System. This Valve has a replaceable Insert that is retained by a screw on plate with hammer lugs. Available in heavy duty standard temperature and high temperature versions.

Oxide coated to fight corrosion while in storage. Available with standard API seats and “modified” API seats.

Design Benefits:

Ø Large metal-to-metal seat bearing area, longer wear life for metal wear areas

Ø 4-Web Seat Design Maximizes Bearing Area and makes Seat Pulling easier

Ø This stem guided valve and seat assembly weightless and provides a reasonable value at an economical price.

Operating Temperature:

Ø Standard Insert – Temperature Up to 80°C

Ø High temperature (HC) Insert - 110°C

Bonded Valve

Premium introduces a new and improved full open valve with bonded insert. The bonded valve has replaced the slip-on

insert to provide a tighter fit. This design is permanently bonded to the valve body. This reduces the tendency for fluids to penetrate between the polyurethane insert and the valve body; preventing failure. This bonded polyurethane insert is also used to minimize shock when the valve closes. The full open design of this bonded valve provides maximum fluid flow, and has a longer operation life due

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

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

→ 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

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.

Hardened Liner

Premium’s Hardened Liner 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.

• Inner bore is nitro carburized and quenched to reach hardness of 60 RC.

• Corrosion resistance, free deformation.

Premium can make the following brand pump Chrome-Plated and Hardened liners and more:

Mud Pump Pistons

Premium’s Pistons are made to precise tolerances and include a variety of materials yielding extended service life. Piston materials include the following from 3” to 7-1/2” sizes to accommodate for all types of drilling conditions, mud properties and temperatures reaching up to 350°F.

Premium provides a full range of mud pump pistons for both triplex and duplex pumps. They are:

Replaceable Rubber Piston

Premium's replaceable rubber pistons are made with nitrile rubber to resist extrusion and abrasion. These pistons are fully interchangeable with most other manufactures products. Available sizes are from 3″ through 7½″ and series are A, B, K and L. If flange is not worn past these marks, rubber kit can be installed Fabric anti-extrusion device reduces extrusion of the rubber even at maximum pressure rating

Features:

Green Duo Piston

The Green Duo piston is a bonded dual durometer piston that is highly resistant to abrasion and tear. The bonded construction resists extrusion under pressure and restricts movement to reduce the build-up of heat.

The Green Duo piston is recommended for systems with oil or synthetic based mud. It is also recommended for water based muds when weights are 11 lb/gal or over. The Green Duo piston is not recommended for clear water or seawater pumping due to the lack of lubricity of these fluids. As in all urethane pistons, the backflush requirement is recommended at 14 gal/min or greater for each piston.

Features:

-Temperature resistance up to 120˚C

-Can be operated in pressures up to 6300 psi

-Backflush requirement is 14 gal/min or greater for each piston

-Not recommended for clear water or seawater pumping due to lack of lubricity of these fluids
