MULTILINE LUBRIC UBRICATOR (also called Radial Lubricator or Multipoint Lubricator) is a user friendly and cost-effective solution for centralized and automatic lubrication of a machine or an equipment having multiple points. Multiline lubricator combines multiple pumps into a single entity sharing a common reservoir and common drive. Wor orking Following steps explain the working of a multiline lubricator - 1. A multiline lubricator consists of a number of small plunger type pumps called as pumping units. 2. These pumping units are located on the periphery of the lubricator housing and their pistons are connected to an eccentric cam. The rotation of the cam provides reciprocating motion to the pumping units. 3. The construction of pumping unit ensures positive suction stroke. This is critical for accurate delivery in each stroke. 4. The cam is driven at a suitable rpm by an electric motor in conjunction with a gearbox. 5. The output per stroke of each pumping element can be adjusted independently. 6. The pressure developed by the pumping unit is sufficient to pump the lubricant and overcome the backpressure at lube point. 7. In grease lubricator, a stirrer is provided to eliminate air trapping and to ensure positive suction of grease. 8. For intermittent lubrication cycle timers are provided Type of driv ive 1. MOTORISED drive with options of following motors a. Three phase motor b. Single phase motor c. DC motor 2. MANUAL drive with easy handle 3. SPROCKET drive by connecting to the machine to be lubricated.
CENLUB SYSTEMS Mutliline lubricator provides following features and advantages Each pumping unit is actuated in each cycle and thus lubricating each line independently. Output of each pumping unit can be adjusted independently. Output adjustment is achieved by just rotating adjusting screw Lubricant of varying viscosity range can be used. Suitable for both oils (even heavy oils) and greases Ensures low lubricant consumption (as low as 0.1cc/ min) even for continuous duty operation Automated operation is provided with the help of a timer to control lubricant cycle and lubricant consumption Multiple drive options available for pump - motorized, manual, drive from the machine to be lubricated High delivery pressures are obtained Multiline lubricator is an excellent solution for longer bearing-life and increased uptime of your machinery. Robust construction makes multiline lubricator suitable for a variety of applications Cenlub Systems multiline lubricator comes with host of features to choose from. Special Featur eatures es 1. Positive suction - Interlocking of pumping unit with cam ensures a positive suction stroke. It ensures accurate deliveries in every stroke. It increases life, increases reliability and consistent performance compared to spring loaded pumping elements. 2. Oil resistant epoxy paint 3. Stirrer - Ensures proper suction of grease in each pumping element avoiding air-pocket formation 4. Simple design which is easy to maintain Pumping Unit sufficient to pump the oils and greases as well as overcoming the backpressure at lube point. Pumping units can be added or removed as per requirement. Tec echnical Specifications ications of a pumping unit - S.No. Factor Sub-factor Values 1 OUTPUT Quantity 0.05cc to 0.25cc per stroke per stroke It is a small plunger pump that gives metered output of lubricant for every stroke. The stroke length of the plunger remains constant. The change of output is obtained by using adjusting screw. Internal construction is such that the rotation of screw results in increasing and decreasing of chamber size. Quantity per minute Adjustment output per stroke x number of strokes per min By rotating the adjusting screw Clockwise for decreasing output Anticlockwise for increasing output Featur eatures es 1. Positive suction stroke for accurate quantity 2. Case hardened element for better life 3. Adjustable doses 4. High pressure output The main element of a multiline lubricator is pumping unit that is put on the periphery of the housing in multiple numbers. The pressure developed by the pumping units is 2. DELIVERY Oil > 200bar PRESSURE Grease > 300bar Caution : 1. Do not plug output of any pumping unit. If the line is to be blocked, remove the pumping unit and plug the opening (Ask for plug M-22*1.5 with sealing ring) 2. Cleanliness of lubricant is of utmost importance. Spurious grease or contaminated oil may damage the lubricator

System Var ariations A multiline lubricator can be used for centralized grease lubrication of a machine having more lube points then the outlets available with the help of Cenlub Systems progressive block (distributors). In practical scenario, there is a need to do some variations in the multiline lubricator to suit its functioning to the application. It could range from having more number of points than number of lines available output proportion is different than what is possible with adjustment in pumping unit lubrication feedback mechanism for complete system lubrication feedback for a cluster of points spraying of grease on open gear The multiline lubricator is used in various permutations as given in diagrams below - Combination of lines to o deliver er more e output Grease spray
