2.3.1. Lubricants
A table is shown that compares the NLGI (National Lubricating Grease
Institute) and ASTM (American Society for Testing and Materials)
categories for greases, limitedly to the values that involve the 989 v2
pump.
For further information on the technical characteristics and the safety
measures to adopt, see the Product Safety Data Sheet (MSDS –
Material Safety Data Sheet) related to the type of grease selected and supplied by the
manufacturer. See paragraph 3.6 on prohibited fluids.
ATTENTION : the pump is designed to work with maximum NLGI 2 grade lubricants. Use NBR gasket
compatible lubricants. Any residual grease inside that was used for assembly and testing is
NLGI 2 grade.
