Multi-line oil lubrication systems consist of the following components: a pump unit, control and monitoring devices, tubing, and fittings. Multi-line pump units supply lubricant to lubrication points without the need for additional metering dividers. As a result, each lubrication point has its own dedicated pumping element. The system design is simple, precise, and highly reliable.

Multi-line pumps can be operated mechanically, electrically, or hydraulically. The easily replaceable pumping elements are typically driven by an eccentric cam. Depending on the drive speed, gearbox ratio, and selected pump element size, a delivery range from almost 0 to 227 cm³/min (0 to 13.85 in³/min) can be achieved. By choosing pumping elements with different piston diameters and/or stroke settings, it is possible to set an individual lubrication volume for each pump outlet. The number of outlets can range from 1 to 28.

SKF multi-line oil pumps are designed for demanding applications across almost all industries and can handle pressure requirements of up to 4,000 bar (58,000 psi).

Multi-Line Grease Lubrication Systems

Multi-line grease pumps can be actuated mechanically, electrically or hydraulically. The easily exchangeable pumping elements are usually operated by eccentric cam. Depending on the drive speed, gearbox ratio and selected pump element size, a delivery range from almost 0 to 35 cm³/min (0 to 2.13 in³/min) can be covered. The built-in stirrer mixes the grease (grease softening process), is synchronized with the pump element suction stroke, and assists the heavy lubricant to low into the suction chamber. This unique concept supplies heavy lubricants usually up to NLGI 3. 

An individual lubrication volume setting per pump outlet is possible by selecting pumping elements with different piston diameters and/or stroke settings. The potential numbers of outlets range from 1 to 30. SKF multi-line grease pumps are designed for demanding applications in nearly all industries. Most pump versions are available with special reservoirs for oil. The P 215 and P 230 pump series enable the use of plasticiser oil for the rubber industry.
