Progressive system
A sequential system is one in which lubricant is supplied continuously as long as the pump is running. When the pump stops during supply, the piston of the distributor valve stops at that position,
When restarting, it operates again from the piston position to supply the remaining lubricant.
Therefore, as long as the pipe at one point is not clogged, it is a system in which lubricant is continuously supplied when the pump operates.
Using such characteristics, it is designed to know the overall operation status of the system even if only one point of pipe is monitored, and it is a system that can control the amount supplied by starting and stopping the pump by timer control.
