Screw-in Restrictors, Metering Valve Distributors, Flow Volume Dividers
A continuous flow oil is often necessary for the lubrication or cooling of machines or systems requiring large amounts of oil. This flow is produced by gear, gerotor, vane and piston pumps and then distributed to meet the needs of the individual lube points.
The system is very simple if there is only one lube point to be supplied. But if the lubricant is to be delivered to a number of lube points in equal quantities or certain proportions, there are several possibilities entailing different expenses and effects.
If must be remembered that circulating lubrication systems require an oil return line from the lube points to the oil reservoir.Adequate filtering of the oil must be provided for. Restrictors, especially for small amounts of oil, are sensitive to dirt.
SKF Single Line Systems for Commercial Vehicles
For fluid grease, NLGI grades 000, 00
Compact units for grease, fluid grease or oil require considerably less hydraulic and electrical installation effort from users than individual components.
All the elements required for a centralized lubrication system to operate are integrated, such as
- drive motor
- grease pump unit / oil pump unit with appropriate valves
- lubricant reservoir
- electronic control unit
- pressure switch
- level switch
- pressure gauge
SKF Progressive Pump Units of the KFG Series
for use in vehicles in automatic oil or grease lubrication systems
Pump units of the KFG, KFGS and KFGC (CAN bus) series are electrically driven reservoir pump units available with and without an integrated control unit. The pump provides on-demand lubricant supply to centralized lubrication systems with progressive feeders or single-line distributors on machines, systems and vehicles. The pump units differ in terms of the size and type of lubricant reservoir, the lubricant filling and their control and function monitoring. Powerful CAN bus versions allow one unit and a special valve to supply up to four independant zones according to demand.
