| Reducing Aeration in Reservoirs |
|
In circulating systems, the aeration of reservoirs can be reduced substantially if diffusers are used to "ooze" the oil back to the tank. Locate the diffuser well below the oil level and select diffuser designs so that flow velocities are reduced to 3 feet per second (fps).

Many extreme pressure gear oils contain sulfurous additives, which can be corrosive under certain conditions, particularly to yellow metals such as copper, brass and bronze commonly used in industrial worm gears and other components. Learn the best approach to selecting the correct lubricant for a given application.

Question: What properties are provided by the additive zinc dialkyldithiophosphate (ZDDP)?
| GET THE ANSWER
Because a change in viscosity, whether an increase or decrease, can be an indicator of a number of problems, monitoring viscosity alone as an indicator of an oil change is insufficient, especially on engines. Find out how setting both upper and lower caution and critical limits can be an alert to oil life and contamination issues.
