Dual line lubrication system is a centralised lubrication system in which grease/oil is fed to lubrication points in measured quantity through Dose Feeders from, a common source. In the system there are two main grease/oil lines which work alternatively. The whole system can be comprises as:

• Motorised Grease Pump Statio
• Inline Filters
• Dose Feeders
• End Pressure Relay
• Tubing and Fittings
• Electric Control Panel

Motorised Grease Pump delivers grease/oil at high pressure to Dose Feeders through in line grease/oil Filters and after the farthest Dose Feeder from the pumping station an end relay is provided. The whole system is commanded by control panel. The pumping station is connected to points through Filters, direction control valve, Dose Feeders etc. When pump will start grease/oil will flow in one of the two lines through direction control valve to the dose feeders and will lubricate the points by feeding set dose. Then pressure will rise and when it will cross the set pressure of end pressure relay. The relay will give signal to control panel and in turn it will give signal to direction control valve of pumping station and grease will start flowing through second line. Now again one dose of grease shall be discharged to lube points and then again pressure will rise to cross the set point of end pressure relay, End relay will give signal to panel to stop pump. In this way one cycle shall be completed.

We offer progressive block. It is a block which is having one inlet port and number of outlet ports. The function of block is to divide the metered amount of grease to each outlet port. This is done by the number of plunger pins moving to and fro in controlled bores in the block. By having the input grease pressure, the first plunger pin moves one side ejecting out controlled amount of grease and simultaneously opens out the passage for input grease to flow into the second bore. Similarly second pin moves to one side ejecting meteres amount of grease from second port, opening the passage for grease for 3rd bore. Likewise similar phenomenon occurs for the 3rd, 4th and subsequent bores.

The progressive block are having different sizes according to thier outlet ports i.e from 4 to 20. The block can be choosed as per nos. of Lubrication Points in the machine. Every point is connected directly to lubrication point.The discharge / stroke is 0.4gms.
