CEVB Pressure-relief Electric Lubricator

Metered oil delivery. PLC-controlled.

Inquiry

1. Operation and interval times are PLC-controlled.

2. Use with positive-displacement distributors for metered oil delivery.

3. Includes a pressure gauge for checking operating pressure.

4. Includes an 8 kgf/cm² pressure switch for detecting oil line damage.

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

6. Includes a pressure regulating valve for pressure adjustment.

7. A special alloy steel gear pump and induction motor provide stable pressure and consistent lubricant delivery, quiet operation and a long service life for general large machinery.

8. An optional forced-feed button enables manual lubrication. An optional indicator lights during PLC-controlled and manual forced-feed operation.

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

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