Remarks
  1. CV progressive feeder can deliver a fixed volume of lubricant to each lubrication point. The standard discharge volume is 0.18cc per stroke. The outlets of the CV progressive feeder can be combined for a larger discharge volume on request.
  2. Each outlet of a CV progressive feeder has one piston inside. The lubricant flow moves each piston, and CV progressive feeder discharges lubricant one by one outlet to complete a circulation cycle.
  3. Forbid to plug any CV progressive feeder outlet, or it cannot discharge lubricant functionally.
  4. Each standard CV progressive feeder has an indicator pin that moves in and out once as a completed circulation cycle. Monitoring can be done visually or electronically with a sensor or proximity switch.
  5. There are two types of inlet and outlet adapters: compression bushings with sleeves and quick couplings. Please follow the instructions below to connect and disconnect a quick coupling.

◆ Instructions on How to Connect and Disconnect a Quick Coupling.

Connecting Pipe witch Quick Coupling Disconnecting Pipe with Quick Coupling
connecting-pipe-with-quick-coupling 1. Make sure the cutting edge of the pipe is smooth and flat. disconnecting-pipe-with-quick-coupling 1. Push down the top of the quick coupling with the thumb and index finger to loosen it from the pipe.
connecting-pipe-with-quick-coupling 2. Insert the pipe into the quick coupling then you will hear two click sounds. disconnecting-pipe-with-quick-coupling 2. Use the other hand to push the pipe into the quick coupling gently. Then,rotate the pipe for approximately a  90-degree angle and simultaneously pull the pipe out.
3. Pull the pipe to check if it is securely locked.

◆ How CV Progressive Feeder Works (Take CV-8 as an example)

cv-progressive-feeder-works 1. The lubricant pressure forces the lubricant to flow into inlet "A",fills up each piston hole with lubricant, and pushes pistons to move to each tap stop.
2. Piston "a" moves to  the left that makes the lubricant changing the flow direction. The original lubricant of the left side piston "a" flows through piston "d" and keeps moving to the first outlets.
cv-progressive-feeder-works 3. After the flow direction is changed, the lubricant moves toward piston "b" which forces piston "b" to move toward the left. The original lubricant of the left side piston "b" flows through piston "a",and keeps moving to the second outlet. 
cv-progressive-feeder-works 4. After the flow direction is changed, the lubricant moves toward piston "c" which forces piston "c" to move toward the left.The original lubricant of the left side piston "c" flows through piston "b",and keeps moving to the third outlet.
cv-progressive-feeder-works 5. After the flow direction is changed, the lubricant moves toward piston "d" which forces piston "d" to move toward the left. The original lubricant of the left side piston "d" flows through piston "c", and keeps moving to the fourth outlet.
cv-progressive-feeder-works 6. After the flow direction is changed, the lubricant moves toward piston "a" which forces piston "a" to move toward the left. The original lubricant of the right side piston "a" flows through piston "d" , and keeps moving to the fifth outlet. The left side circulation is completed.
7. The right-side circulation is the same as the left-side circulation.
