Common questions about 311 Blue Max Grease / NLGI # 0
-
What is Primrose 311 Blue Max NLGI 0 grease used for?
Primrose 311 Blue Max NLGI No. 0 is a lithium complex extreme pressure (EP) grease in a softer grade than No. 2, and Primrose recommends Blue Max 311 in soft and semi-fluid grades for extreme cold and centralized lubrication systems. Primrose lists the 311 line for heavy duty equipment and several bearing types, but publishes typical specifications only for No. 2, so use the grade your equipment calls for.
-
Should I use 311 Blue Max NLGI 0 or NLGI 1 in a centralized lube system?
Use whichever 311 Blue Max grade, NLGI No. 0 or No. 1, your equipment or centralized lube system is designed to pump. On the NLGI scale a lower number means a softer grease, so No. 0 is softer than No. 1, and Primrose recommends Blue Max 311 in soft and semi-fluid grades for centralized lubrication systems without naming the grade numbers.
-
How cold can 311 Blue Max NLGI 0 grease be used?
311 Blue Max NLGI No. 0 is formulated for operation from minus 25 F, according to Primrose, which also cites low temperature pumpability for Blue Max 311. Primrose's data sheet gives no upper operating temperature for No. 0; its approximate minus 25 F to 280 F range is for the No. 2 grade.
-
What is the difference between 311 Blue Max NLGI 0 and NLGI 2?
311 Blue Max NLGI No. 0 and No. 2 are different NLGI consistency grades of Primrose 311 Blue Max lithium complex EP grease, and No. 0 is the softer of the two. Primrose publishes typical specifications, such as the approximate minus 25 F to 280 F operating range, for No. 2 only, so use the grade your equipment calls for.
-
Does 311 Blue Max NLGI 0 resist water and rust?
Yes, 311 Blue Max NLGI No. 0 resists washout and excessive dilution by water and protects steel and copper alloy bearings against rust and corrosion, according to Primrose. Primrose publishes water washout and rust test results for the No. 2 grade only.
