Reliable Lubrication for Continuous Operation
Dual-Line Lubrication Systems are found in virtually every industry in which continuous duty operation is required. From steel production to pulp and paper, from mining equipment to machine tools, automatic application of the lubricant provides significant benefits to the equipment user. There are several components that are used in designing a Dual-Line Lubrication System, including valves, lubricators, reversing valves, central stations, controllers, and spray systems.
Valves
Measuring valves are the heart of Dualine lubrication systems. They are mounted close to the lubrication points and are hydraulically operated by pressure from the first and then the second of the two supply lines. On each pressurisation cycle, they indirectly discharge fixed volumes of lubricant to the bearing or lubrication point.
Lubricators
Manual, electric and pneumatic lubricators store and pump lubricant to Dualine valves throughout the system.
Reversing Valves
These valves change the flow and direction of pressure, which causes divider valves in the system to cycle.
Central Stations
Central stations include lubricator, cycle switch and reversing valve. Some versions are mounted on a plate for easier installation.
Controllers
Programmable controllers give you access to key system functions, such as system on and off, and can control what happens when there is a problem in the system.
Spray Systems
Used to lubricate large gears and pinion sets.
Benefits of Dual-Line Lubrication Systems
- Cost-effective for larger systems: Economical for systems with more than 20 bearing points.
- Easy expansion: Lubrication points can be added without redesigning the entire system.
- System reliability: A blockage between the feed line and bearing does not shut down the system; remaining bearings continue to be lubricated.
- Positive lubrication indicators: Each bearing point has a positive lubrication indicator.
- Versatile lubricant compatibility: Capable of displacing a wide range of lubricants, from light oil to grade 2 grease.
- Adjustable discharge volume: Lubrication volume at each bearing is fully adjustable, even after start-up.
