Product Description
Mobil DTE PM Series products are high-quality, high-performance lubricants
specifically designed for demanding industrial paper machine circulating
systems. They are engineered to provide exceptional lubrication qualities
while protecting system components from rust and corrosion. This is
particularly important in the wet-end where water and chemical contaminants
can enter the lubrication system. The Mobil DTE PM Series oils are formulated
to provide maximum protection of gears and bearings operating under severe
conditions. They exhibit good viscosity characteristics allowing reduced
start-up to production times while maintaining excellent viscosity
characteristics at high temperatures. The DTE PM Series oils provide excellent
resistance to oxidation and thermal degradation, exceptional protection
against rust and corrosion, and a high level of anti-wear performance.
Mobil DTE PM Series oils are formulated with select high-quality base oils and
a proprietary advanced technology additive system carefully balanced to attain
high performance standards. These fluids permit the use of high steam
pressures, temperatures and machine speeds common in high output paper
machines. Their outstanding demulsibility and filterability assure excellent
performance in the presence of water and the ability to retain effective
filtration even at very fine filtration levels. They readily separate water
and retain their colour characteristics for extended periods of operation.
Features and Benefits
The Mobil DTE PM Series oils have proven their performance capabilities in
modern high-output paper machine lubrication. Their excellent performance
properties in the areas of wear protection, enhanced oxidation stability,
chemical stability, effective rust and corrosion protection, colour stability,
and filterability not only extend maintenance service intervals but improve
machine performance and increase production capacity. This results in less
required maintenance, longer equipment life and increased production capacity.
