Hello I am rebuilding paint sprayers and air motor for an industrial paint sprayer. The manual does not specify any particular grease though there is a mixture of materials nitrile, PTFE and viton o-rings and grommets. Housing usually a mixture of Aluminum and stainless steel. V or U seals with UHMWPE, PTFE and leather packings that need to be lubricated during assembly but do not need to be lubricated long term by grease. Most commercial grade pumps I just use multipurpose lithium during assembly of the fluid section but these air motors need to be in good working order for 5+ years. I believe this one made it 12 years before servicing.
Graco just specifies 'waterproof grease'. What to use? Is superlube better than white lithium in this case? Would be best If I can have one grease do everything for these pumps both air motor and during assembly of the fluid section meaning it should be easily cleaned out using lacquer thinner, hot detergent water or mineral spirits without contaminating any wetted parts with silicone.
