GREASE PUMPABILITY Available to Purchase

The factors governing the flow properties of grease are discussed with particular reference to the RN multipurpose grease XG‐274 and the soft lime‐base grease LG‐380. Results obtained at 70°F using a pumping rig with pipes of ½ inch, ¾ inch or ¼ inch external diameter are presented in terms of apparent viscosity in line with the procedure approved by the National Lubricating Grease Institute. The data can be used to assess the suitability of systems proposed for dispensing the greases, supplemented where necessary by apparent viscosity measurement by Standard Method ASTM‐D 1092.
