1. An oil-return system recirculates lubricating oil, reducing oil consumption.
2. A magnetic strainer at the return port prevents iron particles and other contaminants entering the reservoir, keeping circulating oil clean.
3. A PLC can control lubrication and interval times, or the unit can run continuously for long periods without PLC control.
4. A special-alloy steel gear pump paired with a direct-coupled motor provides stable output pressure, quiet operation and a long service life.
5. A pressure-regulating valve allows discharge pressure to be adjusted as needed.
6. Includes a float switch for oil level detection and automatic signaling.
7. A 1kgf/cm² pressure switch detects damage to the lubrication lines.
8. After installation and piping, run continuous forced lubrication to prime the system. Begin normal operation only after the oil lines are completely filled.
9. Refer to the float / float switch specifications for contact information.
10. Refer to the diaphragm pressure switch specifications for contact information.
