Triplex Pump Pistons

SPD provides a wide variety of pistons for mud pump appli-cations, including bonded, urethane, rubber, and replaceable rubber or urethane inserts.

SPD’s bonded urethane pistons are designed for resistance to extrusions and abrasions. With water cooling, these pis-tons will provide optimum performance in oil base mud and high drilling pressures.

• Bonded urethane pistons are rated for drilling opera-tions up to and exceeding 5,000 psi

• Urethane pistons provide extended service life under high pressure

• The Blue Streak™ piston has a higher tolerance to temperature and chemical attack

• Urethane pistons are single durometer

• Bonded rubber pistons are rated for operation pres-sures up to 2500 psi

• Replacable urethane pistons are rated for operation pressures up to and exceeding 5000 psi

• Temperature ratings - Standard urethane - 170°F (77°C)

- Blue Streak™ urethane - 200°F (93°C)

- Rubber - 200°F (93°)

• All bonded and replaceable pistons are available in popular sizes

Zirconia Ceramic Liners

• “HP” Design with shoulder on hull to prevent sleeve slippage• SPD ID tolerances is +.010”/-.000”

- Industry allowance is +.015”/-.000”• Surface �nish 4 – 8 RMS

- Chrome sleeved liner �nish 16 – 20 RMS• Expected run life exceeding 10,000 hours• Hardness: HV 0.3 kg/mm - 1100/1200 (92 – 94 Rc) (Chrome

sleeved liners are 60 – 64 Rc)• Ceramic liners do not create ID ridges which are common

in high chrome liners. ID ridges are a cause of piston failures. Ceramic liners improve piston run life.

• Ceramic liners are pressure rated to pump performance by piston size.

Liners are available in sizes 4-1/2” to 7”.

Liners are available for popular pumps:

EMSCO: FC-2200, FB-1300/1600, F-800/1000 Gardner Denver: PX-11, PZ-10/11, PZ-8/9 National: 14-P-200/220, 12-P-160, 10-P-130 Oilwell: A1400/1700PT Wirth: TPK-2200, TPK-1600/2000

Zirconia Sleeved Liners for Mud Pumps in Drilling Applications

Basic description of Zirconium Oxide/Zirconia: Zirconia engineered ceramic parts can be formed by single axis pressing, isostatic pressing, injection molding, slip casting, or extrusion. Parts can "green machined" to near net size before firing and then "hard" ground using diamond tooling to tolerances less than 0.0002" (0.005 mm). Special grades of zirconia can be enhanced with additives to create a multiphase material and also metallized creating an option to be brazed to metal parts. Applications: Although there are a number of uses for Zirconia, the application of a Zirconia sleeve for a mud pump liner is gaining increasing attention. Although other materials have been used for mud pump liners such as high chromed sleeves and Aluminum Oxide sleeves, Zirconia is gaining favor in this application. A Zirconia sleeve is much harder than a chrome sleeve and therefore offers longer life. Although Ziconia is softer than Alumina, it is not as brittle and therefore will survive low impact shock loading and moderately rough handling. The run life of these two ceramic materials is very close, however because of the careful handling required by Alumina sleeved liners to prevent cracking damage, Zirconia liners are preferred. The Multiphase compound process results in a much smaller grain size which is one of the factors to improve wear life. Properties of Zirconia PSZ MS Grade and Zirconia Multiphase

Operational Characteristics:

Standard chrome sleeve liners wear at a rate of about .007" to .010" on the diameter per 100 hours under normal conditions. When a liner reaches about .070" over nominal diameter the engagement with the piston reduces to a point that blow by begins, resulting in piston failure. The liner wears like a barrel on the ID resulting in the maximum wear at the center of the stroke. The ends of the liner will be at the original nominal diameter. Ceramic sleeve liner will wear in the same way as chrome liners but at a rate of about .001" or less per 100 hours. This rate of wear will result in potential life of 10,000 or more hours. Of course there are a number of variables which would shorten or even lengthen the run time. Recent tests conducted with KCA Duetag and Nabors Drilling have confirmed that wear of only .020” or less have occurred in 4000 hours. Projection of this wear rate would indicate a life of 14,000 hours or more. Urethane pistons are recommended for use with ceramic liners. Piston life in a ceramic liner is variable. The initial piston normally will only run about 200 hours or less. During the initial run the piston further smoothes the liner ID. Subsequent pistons have been known to run much longer up to 500 or 600 hours. However, as the liner becomes worn, the piston lip will begin to loose interference with the liner ID, reducing run life. The above noted run times are dependent on operating conditions. Typical conditions are pressure to 3800 psi, stroke rate to 90 spm, temperature below 170 degrees F, clean mud with weights of 11 to 14 lbs. and a high volume water flush to the back of the piston is required. Higher pressures, stroke rates and temperatures will increase the wear rate.
