4 Therebyincreasing the total number oflubrication points that are servedby a Two-line metering lincoln s high pressure capability allows small diameter tubing to be used, thereby reducing installation and material costs. Additionally, this reduces the amount of grease in the tubing which over a long period of time may deteriorate. Visual or electric monitoring of each metering device outlet pair. If a bearing clogs or a metering device outlet fails to function, all other outlet pairs will continue to function normally.

5 Simple and individual metering of lubricant. Problem-free readjustment of metered lubricant output after installation. Optimum monitoring and control possibility with a field bus system . Easy to Self-thinking SystemThe special components of a lincoln self-thinking Two-line system adjust the system to theoptimum required Two-line systemsoperate on a fixed pressure difference principle. This meansthat the change-over process is then initialized when a fixedpressure at the end of the lineshas been reached.

6 Two-line SystemsConsequently, the system alwaysoperates at a maximum the lincoln self-thinking Two-line system , the pressure isconstantly monitored and modi-fied accordingly. The systemthereby automatically regulatesthe pressure and can compen-sate for temperature adjustments of the system , even during installation,are no longer only the effective requiredpressure is generated duringeach lubrication cycle, the pumpand other system componentshave a longer service life, thesystem always operates in itsmost efficient mode and thegrease is subjected to less Two-line System5closed which causes the pressurein main line (A)

7 To rise, and ismeasured by the pressure trans-ducer. The control unit turns thepump off and signals the change-over valve to relieve main line (A). At this point half of the lubricationpoints in the system have beenlubricated. In the second half-cycle, main line (B) is pressurizedand the cycle continues as Two-line SystemA further advantage is the directdisplay of all important parame-ters on the controller. This enables full monitoring of thesystem and the of a Two-line SystemIn the first half-cycle, the lubricantis pumped into the main line (A)and the main line (B) is connectedto the relief line .

8 The lubricant,which is also the control mediumfor the system , is supplied to themetering devices. The pistons ofthe metering devices are moved into their adjusted end positions,thus dispensing an exact meteredquantity of grease.

As a supply pump for small to mid size Two-line Systems ( F version with filter block, safety valve and pressure gauge) in conjunction with a pressure-controlled change-over valve. The supply range lies within a radius of approximately 50 m from the pump depending on the ambient temperature and type of lubricant.
