KGV Resistance-type Electric Semi-fluid Grease Lubricator

Non-metered lubrication.

PLC-controlled.

Inquiry

1. Operation and interval times are PLC-controlled.

2. A pressure-regulating valve allows line pressure to be adjusted as needed.

3. Includes a forced-feed button for manual lubrication.

4. An optional 20 kgf/cm² pressure switch detects damage to the lubrication lines and automatically sends a signal.

5. An optional capacitive oil-level detector detects a low oil level.

6. A special alloy-steel gear pump paired with an induction motor provides stable discharge pressure, quiet operation and long service life.

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

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

◆ Ordering Code

Model	Tank Capacity (Material)		Voltage		Motor Output Power		Oil Outlet Size		Special Requirements
KGV	03		C		40		3		※
	03	3 L (resin)	A	Single-phase 110 V	40	40W	1	Ø6	PC	Additional pressure switch, NC contact
	04	4 L (resin)	C	Single-phase 220 V			3	Ø6 (with pressure gauge)	PO	Additional pressure switch, NO contact
	05	4 L (aluminum alloy)	D	Three-phase 220/380 V					KC	Add a capacitive oil-level detector, PNP, NC contact.
	08	8 L (sheet metal)							KO	Add a capacitive oil-level detector, PNP, NO contact.

※ Voltage code D specifies a three-phase dual-voltage motor. Factory wiring is for the lower voltage; specify higher-voltage wiring when ordering if needed.
※Capacitive oil-level detection contacts: NO provides a signal when oil is present; NC provides a signal when oil is absent. Specify NPN and NC/NO contact requirements when ordering.
