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)

Grease Pump
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.
Operating Principle
(VP – VPK Series Prog. Feeders)
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.

PSG Modular Feeder Technology
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

Zoned Progressive System
- 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.

Single Line Progressive Systems
Advantages
Disadvantages
• Rugged, versatile design
• System design, layout and installation time and material
intensive
• Modular construction is possible
• Field alterations of system are difficult
• Metering is a function of back pressure and velocity
• Low cost monitoring of spool
movement
• 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
