 Changing
the Face of Seals™
UNCD® Faces bring the tribological benefits of
diamond to mechanical seals used for rotary equipment, such as
pumps and mixers. UNCD Faces are processed using ADT’s patented
diamond technology and provide exceptional life and robustness
to mechanical pump seals.
Benefits
- Longer lasting seals in demanding applications.
- More resisitant to dry and poor lubricating environments.
- Enables the use of hard faces in applications pumping thermally
sensitive media.
- Reduced energy consumption.
- Suitable for a wide range of media.
UNCD Faces
- UNCD Faces (wholesale only): UNCD Faces are available
to seal manufacturers to enhance the performance of their branded
mechanical seals. ADT offers seal faces in a wide variety of
types nad sizes to meet the requirements of seal manufacturers.
Due to the outstanding low friction of UNCD, these faces perform
superbly with a variety of counterface materials, including
carbon and SiC.
- UNCD Seals: A line of component seals with diamond
mating rings and blister resistant carbons is available for
seal users wanting to evaluate a mechanical seal already having
a UNCD face. A line of UNCD cartridge seals for ANSI pumps will
be commercially available soon.
UNCD Faces outperform SiC faces in extreme wear tests. After
thousands of hours of operation, UNCD Faces have consistently
outlasted SiC faces in poor lubricating conditions of 250-300
°F hot water. In head-to-head industrial tests, UNCD Faces
have shown negligible or minimal wear whereas SiC faces experienced
deep grooving resulting in pump leakage. UNCD Faces have also
been shown, when running against SiC, to have coefficients of
friction (CoF) of 0.02-0.04. These are well below the typical
values when running SiC in hard-on-hard applications. The reduced
friction during operation of UNCD Faces results in reduced seal
cavity temperatures when running in ANSI slurry pumping applications.
