Dual Line and Progressive SystemsOverview The dual line system represents the classic solution for lubricating large plants. Progressive distributors are indispensable within modern central lubrication systems as they can cover several lubrication sites with only one supply. Push-pull dosing pistons allow an effective monitoring of the distribution. BEKA supplies progressive distributors for all areas of application. Lubricant: Oil and vicious oil up to NLGI 2 Application Dual Line System: For machines and plants where the groups of lub points are widely separated, such as steel industry, paper machines, coal mining, timber yards. Progressive System: For machines, machine groups and plants where the lub points can be collected in groups, such as presses, punches, cranes.
Dual Line and Progressive System Operating PrincipleThe dual line system delivers the lubricant over a switch-over valve and two main lines to the dual line distributors.
