STANDARD PLATE TYPE VALVE

The Type Valve is extremely durable to its premium forged alloy steel body and its unique design.It has been proven by more than 50 years of oilfield service. To prevent dry pistons and liners at startup, thevalve features a patented double angle polyurethane insert that maintains cylinder priming during pump shut-down. The precise control of insert pre-load is accomplished with a flat ground insert retaining plate and splitretainers. The insert can be replaced in the field with minimum down time. This valve is designed to fit pumps in

Triplex Pump Pistons

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

SPDs bonded urethane pistons are designed for resistanceto extrusions and abrasions. With water cooling, these pis-tons will provide optimum performance in oil base mud andhigh drilling pressures.

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

Urethane pistons provide extended service life underhigh pressure

The Blue Streakpiston has a highertolerance 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 operationpressures up to and exceeding 5000 psi

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

- Blue Streak urethane - 200F (93C)

- Rubber - 200F (93)

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 exceed ing 10,000 hours

Hardness: HV 0.3 kg/mm - 1100/1200 (92 94 Rc) (Chromesleeved liners are 60 64 Rc)

Ceramic liners do not create ID ridges which are commonin high chrome liners. ID ridges are a cause of pistonfailures. Ceramic liners improve piston run life.

Ceramic liners are pressure rated to pump performance bypiston 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

Liners for other pump models and liner sizes available upon request.

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, injectionmolding, 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 ofzirconia can be enhanced with additives to create a multiphase material and also metallized creatingan 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 linerssuch as high chromed sleeves and Aluminum Oxide sleeves, Zirconia is gaining favor in thisapplication.

A Zirconia sleeve is much harder than a chrome sleeve and therefore offers longer life. AlthoughZiconia is softer than Alumina, it is not as brittle and therefore will survive low impact shock loadingand moderately rough handling. The run life of these two ceramic materials is very close, howeverbecause 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 sizewhich is one of the factors to improve wear life.

Operational Characteristics:

Standard chrome sleeve liners wear at a rate of about .007" to .010" on the diameter per 100 hoursunder normal conditions. When a liner reaches about .070" over nominal diameter the engagementwith the piston reduces to a point that blow by begins, resulting in piston failure. The liner wears likea barrel on the ID resulting in the maximum wear at the center of the stroke. The ends of the liner willbe 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 lessper 100 hours. This rate of wear will result in potential life of 10,000 or more hours. Of course thereare a number of variables which would shorten or even lengthen the run time. Recent testsconducted with KCA Duetag and Nabors Drilling have confirmed that wear of only .020 or less haveoccurred 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 isvariable. The initial piston normally will only run about 200 hours or less. During the initial run thepiston further smoothes the liner ID. Subsequent pistons have been known to run much longer up to500 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 pressureto 3800 psi, stroke rate to 90 spm, temperature below 170 degrees F, clean mud with weights of 11 to14 lbs. and a high volume water flush to the back of the piston is required. Higher pressures, strokerates and temperatures will increase the wear rate.
