What Is Verified From Official Catalogs
- Delivery rate 140 cm3/min, tested at approximately 38 bar back pressure and 25 °C.
- Maximum working pressure 38 bar with tolerance plus 2 bar and minus 3 bar.
- Integrated pressure-limiting valve.
- Lubricant fluid grease NLGI 000 and 00.
- Catalog current draw 7.5 A.
No other current draw values from older listings are repeated here. For background on single-line lubrication, see single-line lubrication system.
Reservoir Sizes and Catalog Contradictions
The SKF ordering table lists a reservoir size of 2.7 L. The SKF technical data sheet calls the same unit a 3 L rated reservoir. Both values come from official SKF materials, so this contradiction is real. Confirm the exact usable reservoir volume at quotation.
Do not replace either official value with an unverified number.
What the Unit Does
This gear pump moves fluid grease from the reservoir to piston metering devices in a single-line system. The integrated pressure-limiting valve protects the line from pressure above 38 bar. Delivery is 140 cm3/min under the stated test conditions.
