Sales Meeting June 2006 Vogel Single Line Progressive Lubrication Systems Presented by: Ricardo Gomez
Single Line Progressive System Basic Features Description System distributes grease using progressive feeder valves Hydrostatically sealed spools output metered lubricant Output is a function of back pressure and pump flow Proportional distribution of lubricant Sequential feeding of lube points Operating pressure range: 10 – 200 bar Metered quantities: 0.08 – 3.6 cc Viscosity range: oil and fluid grease (20cSt – NLGI 3)
Progressive System Layout Grease Pump Controller Progressive Feeder with cycle switch Main Feeder Compared to piston distributors, progressive feeders do not operate in strokes – they deliver the amount delivered by the pump divided into the number and size of the pistons. They operate one after the other in a feeder.
Family of Progressive Feeders Typical applications: - oil circulating systems for presses - transfer lines - conveyors/chains - material handling - parts washer - etc.
Piston 4 is under pressure – piston 1 delivers lubricant to the outlet. Piston movement of 1 / 4 opened connection between main line and piston 5 Piston 5 is pressurized and piston 2 delivers lubricant to outlet 2a. Operating Principle (VP – VPK Series Prog. Feeders)
Variable quantity per outlet from 0.004 - 0.2 cu. in. Blind elements for expansion or removal of segments Solid base plate construction-minimizing number of sealing elements-and consequently number of potential leakage points. Also, eliminates over tightening concerns of segmented block construction, which creates leakage. REMEMBER: Leakage in the block construction eliminates the monitoring feature of a progressive feeder-blocked line. That is, a blocked line cannot be detected if the seals associated with that outlet are leaking. PSG Modular Feeder Technology
Integrated check valves on every outlet ISO 228-1179 & SAE ports standard 10 mm / 3/8 “ tube accessible on outlet Check valves integrated into fittings with elastomeric seals Integrated bleed ports Captive O – rings. There are 81 loose o-rings in our competitors design. The PSG has Zero. Imagine the possibility of pinching or loosing an o-ring in during assembly. PSG Modular Feeder Technology
Common Metering elements-Conversion of Twin to Single accomplished is base plate Solid state piston sensing proximity switch Integrated filter possible Integral flow control valves are available - fixed and adjustable - optical or electrical feedback - pressure compensating - gear wheel flow control possible PSG Modular Feeder Technology

-Instead of the whole system only zones, controlled areas by solenoid valves are supplying lubricant. The controller runs the zones in a configured order for a defined time. Zoned Progressive System

Single Line Progressive Systems Advantages Rugged, versatile design Modular construction is possible Low cost monitoring of spool movement Disadvantages System design, layout and installation time and material intensive Field alterations of system are difficult Metering is a function of back pressure and velocity Low volume metering is not reliable Installation is costly Minimum volume – still large for total loss MTBF studies would indicate low up-time (multiplication factor) Series system Susceptible to air locks Additional possible leakage points
