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 an induction motor provides stable discharge pressure, quiet operation and long service life.

5. A fan cools the induction motor effectively and extends lubricator service life.

6. A pressure-regulating valve allows discharge pressure to be adjusted as needed.

7. Includes a float switch for oil level detection and automatic signaling.

8. Includes a 1 kgf/cm² pressure switch to detect damage to the oil circuit.

9. After installation and piping, run continuous forced lubrication to prime the system. Begin normal operation only after the oil lines are completely filled.

10. Refer to the float / float switch specifications for contact information.

11. Refer to the diaphragm pressure switch specifications for contact information.

Single-phase Voltage	Three-phase Voltage	M: motor. GND: ground. Power: Power Supply DS: pressure switch. WS: float switch.

When wiring a three-phase supply, check whether motor rotation is reversed (the motor shaft is marked with a red dot). If rotation is incorrect, interchange any two supply wires.

◆ Ordering Code

Note: Voltage codes D–H are three-phase dual-voltage models, wired for low voltage as standard. Specify high-voltage wiring when ordering if required.
