It is a simple fact: Better lubrication can lead to dramatic energy savings and an improved bottom line. This ought to interest any plant manager who is looking for ways to reduce operating costs, and is especially significant at a time when stricter government regulations are in direct contradiction to reducing costs. Lubrication reliability is the solution. This paper will describe how manufacturing plants can use lubrication reliability best practices to reduce their energy consumption, emissions and operating costs – all at the same time.

We’ve all heard the saying, “Oil and water don’t mix.” Often, this is true, but not always. While certain lubricant formulations are designed to separate from water, others are intended to form a stable emulsion with water. In either case, water becomes a contaminant and can cause major problems both to the lubricants and to the equipment the lubricants are supposed to keep running smoothly and reliably. It is therefore critical to understand the operating needs for specific lubricant applications and to know their desirable water management properties in order to remove water contamination as thoroughly and efficiently as possible. This paper addresses these issues, describes the common causes, characteristics and results of water contamination, and outlines a variety of techniques for separating and removing water from machine lubricants.

Simply stated, viscosity is defined as the internal resistance of a fluid to flow. That doesn’t sound too
difficult, does it? Unfortunately, new temperature, speed and pressure demands on lubricating fluids have changed over the years, resulting in several different measurements and classifications being created to describe lubricant viscosity. Some examples are SUS, cSt, cP, ISO, SAE engine, SAE gear and AGMA; it’s enough to make a person’s head start to spin. This paper will summarize some of the more commonly used viscosity standards, describe the tests used to measure viscosity, and eliminate some of the confusion all of these standards may create for the end user.
