KGBP Pressure-relief Electric Grease Lubricator

Metered lubrication

PLC-controlled.

Cartridge type

Inquiry

1. Operating and pause times are controlled by a PLC. The standard pneumatic pressure-relief version requires an air supply of 4.5–8 kgf/cm²; an electric pressure-relief version is also available and does not require an air supply.

2. Use with a CFB volumetric grease distributor for metered delivery.

3. Includes a pressure gauge for checking operating pressure.

4. A forced lubrication button is provided. Do not hold it continuously for more than 3 minutes, to prevent motor overload.

5. Both single-phase 110V and 220V models include motor thermal protection. At 100°C, the motor stops temporarily for approximately 5 minutes.

6. An optional 60 kgf/cm² pressure switch detects damage to the lubrication lines.

7. An optional reed-switch oil-level detector can monitor level and send a signal automatically.

8. Fill the KGB reservoir through the grease nipple to prevent air and foreign matter from entering.

9. KGBP-07 must be used with a 700 cc bellows-type grease cartridge. Replace the empty cartridge without time-consuming refilling. Cartridges are sold separately; refer to the bellows-type grease cartridge ordering codes.

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

◆ Replacement Procedure

1		Hold the grease cartridge cover firmly and turn it counterclockwise to loosen it.
2		Remove the cover and spring.
3		Turn the empty grease cartridge counterclockwise and remove it.
4		Before installing a new cartridge, squeeze out a small amount of grease to prevent air entering the lubricator.
5		Turn the new cartridge clockwise to secure it to the cover base.

6		Refit the cover and spring.
7		Turn the cover clockwise to secure it to the base and complete cartridge replacement.
