Dresser-Rand Company has initiated the DuraWearTM performance
parts program to help keep compressors reliable, efficient and
cost effective.
Having sold more than 46,000 reciprocating units, D-R has
extensive experience and expertise in state-of-the-art technology
that ensures optimum compressor performance. DuraWear replacement
parts enable Dresser-Rand to provide clients with a complete line
of critical wear parts backed by a worldwide service organization.

"Through the years, our clients in the petrochemical, gas
transmission and gas injection industries have trusted
Dresser-Rand to provide and maintain the most reliable
machines," said David Williams, manager, reciprocating
product upgrades at Dresser-Rand. "We hope they’ll view us
as the single source for premium-quality replacement components,
available in a timely, cost-effective manner."
The complete line of DuraWear performance parts for
reciprocating compressors includes piston rings; rider bands; rod
packing seal rings; oil wiper rings; as well as, pressure,
partition, and oil wiper packing cases.
Made From the Best Materials
DuraWear non-metallic performance parts are constructed from
high-quality unique blends of thermoset and thermoplastic
resin-bonded composites such as Teflon®, PEEK®, and VESPEL®. In
extensive testing and field usage, these advanced materials have
demonstrated superior durability and reliability when compared
with traditional materials. Metallic materials such as bronze and
cast iron also are used in certain applications.
The performance of DuraWear materials in different gases with
different humidities, against different counterface materials has
been tested in the laboratory. Results from one series of tests
(See Figures 1, 2 & 3.) show the effects of humidity on wear
rates of a filled PTFE material, and the reduced wear with TC3
coated rods.
