Mobil SHC PM Series Product Data Sheet

Mobil SHC PM SeriesSynthetic Super Premium Paper Machine Lubricants

Product Description

Mobil SHC PM Series are superior quality lubricants specifically designed for use in severe industrial paper machine circulating systems which lubricate gears and bearings over the widest range of operating temperatures. They are formulated from wax-free, synthesized hydrocarbons and a unique additive system which provide outstanding thermal and oxidation stability, superior protection against rust, corrosion and wear, and excellent filtration efficiency.

The Mobil SHC PM Series have very low pour points and a naturally high viscosity index which ensure good low temperature start-up and high temperature viscosity control. The fluids do not suffer viscosity loss related to mechanical shear in heavily loaded bearings and gears. Their low traction coefficient and high viscosity index result in lower power consumption and reduced component operating temperatures. Hence the life of equipment, filters and the lubricant is extended.

Benefits

Mobil SHC PM Series offer the following benefits compared with the use of mineral oils:

❍ Significantly extended lubricant charge life❍ Excellent resistance to deposit formation❍ Filter life extended significantly❍ Premature bearing failures eliminated❍ Running temperatures reduced❍ Ready separation of water without the need to stop the machine, allowing

optimum operation of wet end bearings❍ Improved filtration efficiency and elimination of clogged pipes resulting in

increased oil flow and better cooling❍ Lower power consumption❍ Excellent protection against rust and corrosion and superior keep clean

performance❍ Higher machine speeds possible and higher steam pressures and process

temperatures❍ Fewer unscheduled stoppages and reduced maintenance costs

Applications

Mobil SHC PM Series lubricants are recommended for paper machine circulation systems, particularly where conditions are severe and where high operating temperatures can result in short oil life, oil darkening and deposit formation with conventional mineral oils and in short filter life. Mobil SHC PM Series provide excellent filtration efficiency even with the very fine filtration used with high-output paper machines operating under severe conditions. This has enabled them to be used both as the flushing oil for a new machine and as the service fill without draining.

Mobil SHC PM Series are compatible with the following seal materials: fluorocarbon, polyacrylate, polyurethane ether, silicone, ethylene/acrylic, chlorinated polyethylene, polysulfide, Viton and Buna-N with low to medium nitrile levels.

Mobil SHC PM Series lubricants are compatible with mineral oils, but admixture detracts from the superior performance properties of the synthetic fluids.
