We are close by. With local branches distributors and partners in cooperation.In Europe, Asia and overseas. Always with specialist service team who speaks your language. Try us.

Single-Line Systems

Single-line central lubrication systems are used mainly for the lubrication of machinery with following specification:

Lubrication points: up to 100
Pipe length: up to 30 m
Pump pressure: up to 160 bar

Example of application: General mechanical engineering, bottle cleaning machinery, calanders, plate conveyors, presses, type moulds, packaging machinery, machine tools, brickworks machinery, e.g.e.

Mode of operation: The central lubrication pump feeds the lubricant into a main distribution line which runs alongside the machines. Branches lead to distributors of type ZE - C mounted singly or in groups in the vicinity of the lubrication points. Their function is accurately to meter the lubricant and to deliver it to the lines leading to the lubrication points, even against high back-pressures. During one lubrication cycle the main line is pressurised, where upon metering of the lubricant to the lubrication points takes place. The pressure in the main line is then released into the suction chamber of the pump, causing the lubricant in the distributors to be supplied to the other side of the plunger, in readiness for the next cycle.

Dual Line Systems

Centralised lubrication systems with two main feed lines are chiefly used for the lubrication of machines and plant with a large numbers of lubrication points:

Lubrication Points: up to 1000
Pipe Lenght: up to 150 m
Pump Pressure: up to 400 bar

Example of application: Smelting plant, rolling mills, mining power stations, cement works, sugar refineries, breweries, construction machinery, etc.

Configuration: The lubrication system consists principally of the pump, one 4/2-way or two 3/2-way change-over valves, the two main feed lines, the distributors arranged close to the lubrication points, the lines leading to the lubrication points, witchgear at the line end, the pressure gauge unit and the controls. A pressure relief valve is required to protect the pump from over pressure.

Mode of operation: The delivery side of a lubrication pump and the lubricant tank for the pump are connected alternately, via a change-over device (a 4/2-way valve) to each of the main feed lines. As many main distributors as required can be connected to the two main feed lines. The lubricant pressure causes half the lubrication points conected to the distributors to be supplied with a quantity of lubricant depending on the volume swept by the plunger. The change-over operation is then initiated either manually or automatically; this causes the main feed line which had been under pressure to be connected to the pump tand and the previously unpressurised main feed line to be connected to the pump delivery, whereupon lubricant is supplied to the other half of the lubrication points. There then generally follows an interval in the lubrication process.

Multi Line Systems

Lubrication Points: up to 36
Pipe Lenght: up to 40 m
Pump Pressure: up to 100 bar

Application: Using the multi-line system, centralised lubrication systems can be used for lubricating individual machines and small groups of machines or appliances. In the multi-line system, the lubricant is delivered by the pump in metered quantities through several outlets. Each lubrication point is connected to the pump by its own line.

Maximum number of lubrication points: The design of the lubrication pumps, limits the maximum number of lubrication points which can be supplied by direct line 32. A further increase in the number of lubrication points is possible if progressive distributors are used.

Maximum length of line: The maximum permissible length of line from the pump to any lubrication point depents on the characteristics and pumpability of the grease, the size of the feed line, the delivery pressure of the pump, the rate of flow and the operating temperature, and as a rule from 20 to 40 m is acceptable. If the lines are too long, the line resistance will exceed the pump pressure.

Mode of operation: Each lubrication points has its own line connecting it directly to the pump. The lubrication pump develops the pressure necessary to pump the lubricant and overcome the back pressure and it meters the quantity of lubricant required for each lubrication point. The lumbricant pumped through any particular line can be delivered up between a number of lubrication points if required, by incorporating a progressive distributor.

Progressive Systems

Application: Centralized lubrication systems with progressive distributors preferably serve the lubrication of machinery. The lubrication capacity is up to approx. 100 lubrication points per system. The systems are suitable for grease and oil.

Example of application: Machine tools, packing machinery, presses, punching presses, cutters, woodworking machinery, etc.

Mode of operation: Progressive distributors distribute the lubricant to the lubrication points connected to their outlets, in small metered quantities progressively in a given sequence. When the last lubrication point has been supplied, the process of lubrication automatically starts again at the first lubrication point. If lubrication is interrupted at any point, because the pump is switched off or the delivery line is blocked, it continues from the same point when the system is re-started.
