Dual Line Lubrication System By Techno Drop Engineers

This type of Dual Line Lubrication System basically consists of a reservoir with inbuilt reciprocating plunger pump, reserving valve, dose feeders, and pressure relay and pipings. In this system, there are two main supply lines which are laid parallel to the equipment to be lubricated. Inlet to dose feeders are connected to those two lines and the outlet from the feeders are connected to point of lubrication.

The pump feeds grease alternatively into the two main lines through the reversing valve. The end pressure relay is located at the farthest point from the pump which trips the pump motor and changes position of the reversing valve as soon as a preset pressure is achieved in the line being pressurized. This completes the cycle. The next cycle is started through an adjustable timer.
