Modular feeder PSG product series For oil and grease For use in SKF ProFlex progressive and SKF CircOil circulating centralized lubrication systems Metal-forming machinery (presses) Tunnel boring machinery Paper machinery General mechanical engineering applications Advantages • Easy to service thanks to outlets located in the baseplate; tubes do not need to be removed during repair work; between 1 and 20 outlets • Flexible due to replaceable metering sections • Expandable by attaching flow limiters, flow controllers, gear-type flow indicators, and directional solenoid valves.Efficient due to low pressure loss • Can be monitored using piston detectors or visual cycle indicators • Adjustable by consolidating outlets internally and externally • 3 sizes for ranges up to 0.8, 2.5, and 6 l/min • Increased functional reliability due to check valve installed standard (PSG2 and PSG3) • Increased metering accuracy due to placement of integrated check valves immediately following metering piston (PSG2 and PSG3) • Increased corrosion resistance due to special design with anodized baseplate and chemically nickel-plated sections (basi

PSG product series Product description Operation († Figure 1) Observation of the movements begin the moment that all three pistons (A, B, C) on the left end stop show that the lubricant and operating pressures reach from the inlet through the through-duct in the middle to the pistons C-right, B-right and A-left; that is, while pistons C and B retain their positions, the A piston is pushed right. The lubricant volume specified by the piston diameter and stroke is pressed into a duct on the end (outlet 4) the same quantity exits. This stroke movement of piston A opens or closes multiple control...

PSG product series Monitoring and attachments Monitoring All standard sections can be monitored directly or retrofitted with a piston detector. However, if the piston movement will be monitored by a cycle indicator (visual stroke monitoring) or a proximity switch, the appropriate sections must be used. The modular structure of the modular feeders is particularly apparent in the range of available attachments. Depending on frame size, it can be equipped with the following upstream equipment: • Flow limiter • Flow controller • 4/2-directional solenoid valve • 2/2-directional solenoid valve If the...
