1. A timer controls lubrication and interval times. The controller has operation (ACT), alarm (ALM), lubrication (RUN) and interval (INT) indicators, plus a small built-in buzzer.
2. Stores the set lubrication and interval times.
3. Includes a pressure gauge for checking operating pressure.
4. Includes a float switch for oil level detection and automatic signaling.
5. A pressure-regulating valve allows pressure to be adjusted as needed.
6. A manual lubrication button (F button) provides forced lubrication.
7. Models with tanks of 3L and above can be fitted with a 1kgf/cm² pressure switch to detect damage to the lubrication lines.
8. A special alloy-steel gear pump paired with an induction motor provides stable discharge pressure and a reliable supply of lubricating oil to each lubrication point. Quiet operation and long service life suit general large machinery.
9. Refer to the float / float switch specifications for contact information.
10. Refer to the diaphragm pressure switch specifications for contact information.
