1 Gear pump unit roduct series KFB For high-viscosity oils and fluid grease of NLGI grades 000, 00 For use in SKF MonoFlex single-line centralized lubrication systems SKF gear pump units of the KFB product series are used to supply lubricant to SKF MonoFlex single-line systems. They are designed for use on commercial vehicles, systems, and machines. The commercial vehicle version has type approval pursuant to ECE-R 10. SKF gear pump units of the KFB product series are designed for the supply of fluid grease of NLGI grades 000 and 00. They include a pressure-relief valve and a pressure-limiting valve for the operation of intermittently operated MonoFlex single-line systems. The distribution and metering of the lubricant to the lubrication point can be accomplished using SKF MonoFlex singleline distributors. The gear pump units are designed for supply voltages of 1 V DC and V DC. They are controlled either by a built-in electronic control unit or externally, via the machine control system. An optional fill level switch can be selected to monitor the fill level. Depending on the design, the gear pump units are filled via a filler socket or an attached filler coupling. Their compact design makes gear pump units of the KFB product series the ideal solution for the assembly of small centralized lubrication systems on commercial vehicles and machines with few lubrication points.

2 roduct series KFB roduct overview KFB1 KFBS1 with integrated control KFBS1-6-S1 with VN relubrication distributor KFB1-M-W KFBS1-M-W with integrated control KFB1-M-W-S1 SKF gear pump units of the KFB product series differ principally in their options for electrical connection and in control and function monitoring. The pump casing contains the mounting flange, the mounting plate for the hydraulic connections, the electrical connection, and in the case of controlled models, also the display screen of the electronic control unit built into the pump casing. Gear pump units of the KFB1 group are not controlled and therefore do not contain a built-in control unit. Gear pump units of the KFBS1 group contain an integrated electronic control unit that can be programmed via the display screen on the front of the pump casing. The electronic control unit regulates the functions of the gear pump unit and monitors the fill level. If available, an external pressure switch can also be integrated into the monitoring system. The mounting plate for the hydraulic connections includes the pressure-limiting valve, the pressure-relief valve, and the lubrication line connection. For models with a follower piston, there is always a filler coupling fitted on the mounting plate for filling the lubricant reservoir. With models without a follower piston, the lubricant reservoir can also be filled directly through a filler socket on the reservoir surface. The lubricant reservoir is mounted on the pump casing and is made of transparent plastic with markings for visual monitoring of the fill level. Models with automatic fill level monitoring contain a fill level switch as well, which is either separate in the lubricant reservoir or acts together with the follower piston to issue a signal when the lubricant level is too low. Gear pump units in the KFB1 group are fitted with a pushbutton on the pump casing for triggering interim lubrication. On gear pump units of the KFBS1 group (controlled), interim lubrication is triggered via the electronic control unit's display screen. UB LS/ 1658 EN EN

These five competence areas include bearings and units, seals, lubrication systems, mechatronics (combining mechanics and electronics into intelligent systems), and a wide range of services, from -D computer modelling to advanced condition monitoring and reliability and asset management systems. A global presence provides SKF customers uniform quality standards and worldwide product availability. Important information on product usage! All products from SKF may be used only for their intended purpose as described in this brochure and the operating instructions. If operating instructions are supplied together with the products, they must be read and followed. Not all lubricants can be fed using centralized lubrication systems. SKF can, on request, inspect the feedability of the lubricant selected by the user in centralized lubrication systems. Lubrication systems and their components manufactured by SKF are not approved for use in conjunction with gases, liquefied gases, pressurized gases in solution, vapors or such fluids whose vapor pressure exceeds normal atmospheric pressure (1 01 mbar) by more than 0,5 bar at their maximum permissible temperature. In particular, we call your attention to the fact that hazardous materials of any kind, especially the materials classified as hazardous by EC Directive 67/58/EEC, Article, ara., may only be filled into SKF centralized lubrication systems and components and delivered and/or distributed with the same after consultation with and written approval from SKF.
