WHAT IS THE DIFFERENCE BETWEEN SERIES PROGRESSIVE AND PARALLEL AUTO LUBE SYSTEMS?
In a single line progressive system, a pump delivers the lubricant to the lubrication points via progressive metering valves custom-sized for each application points. Lubricant flows through a primary valve which redirects to multiple secondary valves, and finally through feed lines to the ultimate application points. The nature of this system is such that if any line/bearing is not taking grease the entire system shuts down and there is (in a properly designed system) visual indication to the operator there is a problem. This allows the operator an opportunity to take action before any damage occurs.
