Product: VSG8-KR Two Line Metering Device
1. Strictly Tested: Using 32# or 46# mineral thin oil tested, thinner than greasing oil, it will guarantee lubricates to every corner of the long distance lubrication spots.
2. Strength Raw Materials: High strength carbon steel as raw materials, extend the service life and lowering the damage chance in several years.
3. Standard Industrial Dimensions: The standard installation dimensions making the equipment with easily replacement and saving repair cost largely.
Dual Line Metering Device VSG8 Introduction
Dual line metering device VSG8 is for centralized lubrication system, which with tow supplying grease or oil pipes and eight feeding outlets to each lubrication points.
Dual line metering device VSG8 should preferred use parallel installation in the lubrication system, outlet pipes and divider valve are available to be installed on left or right side. The second method is to adopt series mounting, not allow more than three outlet numbers. The parallel and series are used together for some certain occasion.
The connection surface of the divider and pipe should be smooth, the installation bolts should not be too tight when mounting the divider valve. The block bolts on both side should not be dismounted while operation, the sealing or O- ring should be change if there is a leakage, please consult the manufacturer for spare parts.

Dual Line Metering Device VSG8 Position of Lock Screw Condition
A – Lock screw
B – Rotary slide horizontal: 2 outlets
– Rotary slide vertical: 1 outlet
With the two main lines being relieved (i.e. when the pump is switched of) the lock screw A can be closed and the rotary slide B can be turned through 90°. If the rotary slide is put into position 1 the connecting passage between the two outlets is closed, and the lubricant is discharged by the two outlets. If the rotary slide is in position 2, the connecting passage is open. In this case one of the two outlets has to be closed by means of a closure plug, and then the double lubricant volume is discharged by the other outlet.
Dual Line Metering Device VSG8 Working Operation Graphic
Pressurized lubricant is supplied to the metering device via main line I. The control piston (1) starts moving in the direction of arrow A, displacing the lubricant in front of the control piston into the relieved main line II.
When the control piston (1) uncovers the connecting passage (2) lubricant is transferred to the right end of the dispensing piston (3), thereby displacing it to the left in the direction of arrow A.
The lubricant volume ahead of the dispensing piston is transferred via the connection passage (4) to the lubrication point. With the dispensing piston in its terminal position, the pressure in main line I will continue to rise to reach the preset change-over pressure of the two-line system. At this stage,the change-over valve of the system operates to connect main line I which has so far been under pressure to the lubricant reservoir of the lubrication pump.
At the same time the change-over valve connects main line II to the lubrication pump, thus pressurizing the lubricant in this main line. The control piston (1) moves in the direction of arrow B, displacing the lubricant ahead of the control piston into the relieved main line I.
When the control piston (1) uncovers the connecting passage (5) lubricant is transferred to the left end of the dispensing piston (3) and displaces it to the right in the direction of arrow B. The lubricant ahead of the dispensing piston (3) is transferred via the connecting passage (6) to the lubrication point. With the dispensing piston (3) in its terminal position, the pressure in main line II will continue to rise to reach the preset changeover pressure of the two-line system. At this stage, the change-over valve will once again cause a pressure changing-over in main lines I and II and the cycle will be repeated as described in stage 1.
Dual Line Metering Device VSG8 Output Volume Adjustment
Variation KR for infinitely variable adjustment and visual indication.Infinitely variable adjustment of lubricant output is achieved by turning the adjustment screw F. Maximum output is available if the lock screw E and the adjustment screw F are in their uppermost position. By turning the screw downward the output can be continuously reduced. With the two screws in their fully closed position, the indicator pin G is completely restrained and, because the pin is attached directly to the dispensing piston, the lubricant output will be nearly zero.
The indicator pin shows the correct functioning of a pair of outlets. After setting the lubricant output, the adjustment screw F will be locked in position by means of screw E.
To secure the setting, lock the adjusting screw only when the indicator pin is retracted.
