Don-Nan Pump and Supply

Don-Nan has been supplying the onshore oil & gas production market since 1962.

Barrels in chrome surface steel, nickel carbide and hardened and honed.

Cages and Fittings

• STEEL-carbon steel material for most cages and connecting parts. Recommended for mild to average pumping conditions where abrasion and corrosion are not a problem.
• STAINLESS-304-recommended for corrosive environments
• STAINLESS-316-higher grade stainless with better corrosion resistance than 304
• MONEL-for extreme corrosion and heavy deep well applications
• BRASS-admiralty brass recommended for mild abrasion and average to severe corrosion.
• ALLOY-special high strength alloy steel parts made upon request for special applications.
• HARDLINED-for increased cage life, cages are available with a #6 genuine stellite lining on ball guides. Available in steel, stainless, and monel.

Plungers in spray metal surface, chromed, 316 SS and grooved body.

• METAL PLUNGERS
  Don-Nan offers plungers for both insert and tubing pumps. Precision ground on the OD, our plungers meet all API specifications. Available in pin-end and box-end. Pins are available in Monel, stainless steel, alloy, and other materials as requested.
• SPRAY METAL
  Don-Nan’s spray metal plungers are recommended for severe corrosion and abrasive conditions. Our precision tubes are ground on the OD and flame sprayed with a nickel base alloy powder containing chromium, boron and silicon to create a hard coating (R’c 58/62). Available with different pins and also box end plungers for tubing pumps.
• CHROME PLATED
  Don-Nan’s chrome plungers have a hard chrome plate (R’c 70) that are resistant to abrasion where corrosion is not a factor. Available in all sizes with box end plungers for tubing pumps. 
  
• GROOVED PLUNGERS
  Available in both spray metal and chrome plated.

Balls and seats available in all materials.

• STAINLESS STEEL- ball and seat are made from a series 400C stainless steel and are oil quenched and tempered to develop good abrasion and moderate corrosion resistant properties.
• TITANIUM CARBIDE-a powdered metal material, not a cast material as found in alloy, this ball is homogeneous throughout, the outside skin is the same as its core, one of the reasons it earns a Rockwell hardness rating of 90. Titanium has more abrasion resistance, will not deform, and has better pitting resistance than alloy.
• TUNGSTEN CARBIDE-excellent abrasion and corrosion resistant properties, carbide balls and seats are recommended for the most abrasive fluids.
• ZIRCONIA-made from partially stabilized Zirconia, valued for its unique properties of inertness, high temperature stability, strength and toughness. Corrosion and impact resistant.
• SILICON NITRIDE (DURABALL)-Si3N4 is light, hard and has low thermal expansion coefficient. It has high mechanical strength, fracture toughness, and it is resistant to deformation. Particularly resistant to corrosion and abrasion.
• NICKEL CARBIDE-nickel binder material is advantageous when both corrosion and wear resistance are required. This material suited for more impact when compared to other Nickel grades.
• ALLOY- non-ferrous, non-magnetic cobalt-chromium tungsten alloy in which very hard, microscopic carbides are uniformly distributed in a tough, shock resistant matrix. The result is a ball and seal with exceptional resistance to both abrasion and corrosion

On–off tools, sheer tools, inserted guide cages.
Gas separator–patented design for all machined rather than welded.
