  • Page 3: General System Description

    SKF Multilube-central lubrication system SKF Multilube system is a single- or dual-line (Heavy- or Twinheavy) central lubrication system, in which the lubricant is pumped through piping to the dosers. Dosers feed the pre- set amount of lubricant to the lubrication points.

  • Page 6: Multilube Pumping Unit

    SKF Multilube pumping unit General description The pumping unit is designed for pumping lubricant into central lubrication system. Design Pumping unit comprises of a body (pos. 1) and a lubricant reservoir (pos. 2). The body comprises of a pump element (pos. 3), an electric motor (pos. 4), a line valve (pos.

  • Page 7: Operation

    Operation When pressurization begins, the control starts the pump and opens the line valve. In pres- sure switch operation the pump stops, when the pressure switch closes and restarts, when the pressure switch opens. After the set pressurization time, the control stops the pump and pressure discharges from the line to the lubricant reservoir.

    B-doser groups, Heavy-system General description Note Numbers in brackets are part numbers of drawings 461780 in the page 16. A doser group consists of a mounting rail (pos. 1) and one or several dosers (pos. 2) fas- tened to it. The mounting rail divides the lubricant to the dosers, which feed the adjusted amount of lubricant to the lubrication points.

    SMG-dosers, Twinheavy-system General description SMG-2 doser feeds the preset amount of lubricant to one to eight (1 – 8) lubrication points. Design The doser includes a disk valve (pos. 1) and a dosage cylinder (pos. 3) which is equipped with sealed piston (pos.

  • Page 20: Adjustment

    Dosers with one outlet The doser with two outlets is modified to doser with one outlet by removing the disk valve and the lubrication outlet connection and replacing them with blocking plug (pos. 7). During normal sequential operation, doser with one outlet feeds the lubricant in turns to lubrication outlet connection and to one of the main lines.
