Lubricant Leakage is Not Acceptable

Oil mist bearing lubrication systems are used extensively in refining, power, manufacturing, pulp & paper, steel, chemical, and offshore facilities using rotating equipment. This form of bearing lubrication is highly successful in providing reliable and cost effective lubrication to bearings in pumps, motors andyes other types of rotating equipment.

Oil mist is a centralized system that uses compressed air to produce a clean mixture of low-pressure, atomized lubrication oil in precise amounts to provide a continuous supply of clean lubrication to bearings in up to 60 pieces of rotating equipment. Figure 1 shows a typical oil mist system.

There are numerous benefits to using oil mist systems, which are most commonly used on centrifugal pumps, including:

Oil Mist Benefits

  • Reduced Required Maintenance

  • No Oil Changes

  • Reduced Lubricant Consumption

  • Lower Friction

  • Lower Temperatures

  • Mist Blocks Contaminants

  • Reduced Wear

However, one of the widely recognized concerns with oil mist systems is the stray mist that escapes from the bearing housing past labyrinth type devices as shown below.

In addition to providing superior sealing and protection functionality the Isomag MP-V7 offers:

  • A high level of MTBR – projected operating life of 100,000 hours at 12,000 sfm (60 mps)

  • Low operating temperature – does not increase the operating temperature of the bearings

  • Easy installation and removal – O-ring fit on the OD of the MP-V7 makes it easy to install and if necessary remove and reinstall.
