Product Description
UNCD®
is a form of diamond that features very low friction, chemical
inertness, and superior wear resistance. UNCD Faces are offered
to OEM and seal manufacturers enabling easy access to the benefits
of diamond faces. Custom and small-lot quantities of UNCD Faces
are routinely produced to our client's engineering drawings providing
a "drop-in" improvement to current products and enabling
new products with the benefits of diamond. Additionally UNCD Type
M05 Stationary Seats are offered for standard ANSI pumps requiring
O-ring style mating rings. UNCD Faces have a smooth, thin film
of UNCD on silicon-carbide (alpha phase, self-sintered) to improve
mechanical seal service life and performance and can be mated
against either conventional SiC or carbon counterfaces.
Benefits of UNCD Faces
- Offer the compelling benefits of diamond to your customers
with a minimum investment and risk
- Longer lasting seals in demanding applications
- Increased energy efficiency
- Reduced downtime and maintenance costs
- Performs exceptionally well against carbon and silicon carbide
counterfaces
- Greater tolerance to dry running and poor lubricating conditions,
abrasive slurries, and liquids above their boiling point
Applications and Features
UNCD Faces are designed for industrial applications
including chemical, pharmaceutical, petrochemical, food and beverage
processing, power generation, pipeline, and pulp and paper. They
are particularly suitable for poor lubricating environments, including
hot-water and applications that include temperature sensitive
media. The low friction of UNCD Faces enables them to be mated
with a variety of rotary seal materials including carbon-graphite
and silicon carbide. The coefficient of friction (CoF) of the
UNCD-silicon carbide combination is between 0.02 - 0.04, well
below the CoF values of running carbon against silicon carbide.
In extreme wear tests, the combination of
running UNCD against carbon has far outperformed silicon carbide
running against carbon.
Product Offering
UNCD Faces are offered to customers engineering
drawings in sizes up to 12 inches OD. UNCD Type M05 Stationary
Seats are offered in five sizes to accommodate ANSI pumps with
shafts from 1.125" to 2.125" diameters. See below for
dimensions and related information.
For a quotation for your application, please
provide the outside dimensions and/or an engineering drawing and
your volume requirements. ADT will provide a quotation for your
approval.
