Contamination Control
Contamination in lubricating oils is the root cause of premature oil degradation and
accelerated wear of machine components. Prevention and control of contamination is
very often the most reliable means of preventing equipment failures. |

Constant Level Oilers - Vented versus
Non-vented
Constant level oilers have been utilized on process pumps for over 60 years. Over the
years, advances in seal technology and more focus towards contamination control has
brought forward new advancement in constant level oiler technology. In this paper you
will learn the importance of maintaining proper level of lubrication with constant level
oilers. |

Maintaining
Proper Quantity/Quality Lubrication in Horizontal Pumps
Proper lubrication in a process pump is critical to component’s function and longevity.
Key points to obtaining proper lubrication: 1) lubrication fundamentals 2) how the pump
is designed for providing lubricant to the bearing and 3) and surrounding environment.
Some basic lubrication fundamentals, types of lubricant, and different methods currently
used for providing lubrication to the bearing will be covered. |

Effects of Aeration on Industrial Lubrication
Equipment
Almost all lubricating oil systems contain some air.
Air is found in four phases: free air, dissolved air,
entrained air and foam. Free air is normally found
trapped in a system, such as an air pocket in a dead
leg of a piping system, and may have minimal contact
with the fl uid. It can be a contributing factor to
other air problems when lines are not bled properly
during equipment start-up and free air is drawn
into circulating oils. |

Constant
Level Oilers
Constant Level Oilers are design to maintain a predetermined oil level in a sump, which is necessary for proper lubrication. If the oil level drops below this point, the depleted oil is automatically replenished by the lubricator, returning it to its original level. |

Thinking about a
Change?
Although many types of lubrication
methods are available for
bearings in horizontal process
pumps, the most widely used method is
still oil sump lubrication.
The most common form of bearing
lubrication is direct contact.As the shaft
rotates, the rolling elements in the bearing
— typically steel balls — make contact
with a controlled level of oil. |

Effective Constant
Level Lubrication
This article outlines the critical elements of
oil sump lubrication, and how to properly select and use constant level oilers to ensure effective oil sump lubrication. |

Micro-Improvement
Imagine tripling parts production
while extending tool life and significantly
reducing the use of cutting
fluids, coolants or lubricants. It’s
possible with a fluid-mist-dispensing
system.
With these systems, which have been
around for many years, the lubricating
fluid used makes up less than 1 percent
of the air-fluid mixture. As a result, the
lubricant is essentially consumed during
machining. No residue is left on the
machine or workpiece, nor is there any
airborne mist. |

Best Practices
in the Application and Maintenance of Oil Sump Lubrication of Horizontal
Process Pumps
Brad Rake is the Vice President of Technology and Market Development for Trico Mfg. Corp. In Pewaukee, Wisconsin. He received his degree (Design, 1978) from the University of Kansas, and has been involved in the pump industry for 10 years. Currently serving as the chairman of the Housing Technical Committee for the Hydraulic Institute, and a member of the Pumps and Systems Magazine Advisory Board, he is a recognized author and speaker on the subject of industrial equipment lubrication. |

Prescription for Better Lubricant Health & Life
Just as maintaining a healthy lifestyle can result in a longer and higher quality of life for human beings, so it goes for
industrial equipment lubrication. Recently introduced products that protect lubrication should be considered as a part of
maintenance programs designed to keep equipment "healthy". |

Optimizing Oil Sump Bearing Lubrication in Process Pumps
Anti-friction bearings in process pumps
often, by design, utilize oil sump lubricated
technology. As simple as this method is,
there are many critical elements that will
degrade the overall performance of the lubricant,
resulting in premature component
failure. Specification of lubricant type,
bearing housing configuration, maintenance
methods and condition monitoring are all
key elements to consider for improved reliability
of horizontal pumps used in pulp &
paper, refining and chemical operations. |

Bearing Protection Device and Equipment Reliability
To this day, important lubricant-application
and bearing-protection issues are
overlooked or misunderstood in the typical
process-plant environment. Solid explanations
are not widely disseminated and industry
sacrifices potential equipment reliability
For decades, constant-level lubricators
have been the standard lubricant-supply
system for huge numbers of bearing
housings. They have been used on millions
of centrifugal pumps, gear units, and
electric motors with oil-lubricated
bearings. However, certain types of
constant-level lubricating devices require
an understanding of how they function,
and can be misapplied. When lubricators
are misapplied, bearings could be deprived
of lubrication and may fail. |

Micro-Dispensing Cuts Lubricant Usage by 99%, Results in
High-Value Dry Chips
Imagine being able to increase part production by
three times while using a fraction of the cutting
fluid, coolant, or lubricant; or, if you prefer,
imagine gaining similar improvement in tool life. |
