The lubricant coming from the pump is divided up by progressive feeders in defined ratios. The distribution of lubricant to the lube points is performed by pilot controlled valves and this is done in predetermined order.
Each piston can execute its stroke only after the one before has completed its. Thus the outlets of the progressive feeders and the connected lube points receive lubricant one after another. If the pump continues to operate, after delivering lube from the first to the last lube point, the cycle will be repeated. The valves resume operation at the position they were stopped when the pump starts to function again.
The operation and stand-by periods of the pump can be electronically regulated and the number of outlets as well as the dosage can be adjusted according to operators preferences.
Each of the feeder section has two respective outlets and the amount of lube supplied per stroke is determined by the pistons diameter.
In case that a lube point does not accept any lubricant - whatever the reason - is or if a feeder piston is blocked, the entire feeder as well as the entire lubrication cycle stops. One of the advantages of the progressive system is that the situation can be used to emit a signal when the system is monitored
SINGLE LINE SYSTEM WORKING PRINCIPLE
The operation intervals of the pump are adjusted by the operator on the electronic control card and automatically actuate for preset periods. The dispensers lubricate once at each operation in adjusted dosages. If manual pump is used, pumping is continued until the pressure lever becomes harder to be pressed.
TWO LINE SYSTEM WORKING PRINCIPLE
Pump delivers lubricant through first line and fills until the pressure value to which the pressure switch is adjusted. Meanwhile the first chambers of the valves are filled with lubricant. the valve changes its position as soon as it receives the signal from the pressure switch and begins to deliver lubricant through the second line. While the pressure increases in the second line, the lubricant is filled into second chambers of the valves. At this time, the lubricant in the first chambers of the valves is delivered to the lubrication points. Lubrication is performed as long as this process continues. The lubricant quantity can be adjusted either from the valves or by changing into two separate lines can be done by using a pilot controlled changeover valve or a selenoid valve.
MULTI LINE SYSTEM WORKING PRINCIPLE
Each pump element on the main pump body is connected directly to one lubrication point or to one progressive valve. Each pump element is adjusted separately for optional dosages. If needed, an electronic control card can be used to control each distribution line
