I have several bike pumps and I'd like to know what is the proper grease to keep them working properly?
Spray a small amount of silicone lubricant inside the barrel of the pump to lubricate the plunger. Do not use oil-based lubricants, including WD-40 type of products. Hot compressed air and flammable lubricants are not a good combination.
ive always used phil wood on my pumps and never have had any problems with it or any similar grease
Any thin grease is fine. Just a light smear though. Or a spray of silicone lube would work well too. I'd avoid oil though since it'll run and you risk blowing it into the tube. And rubber doesn't generally like oil.
Supcom, I know you're on a safety kick but our pumps can't build up the pressure or heat required to "diesel" oils or greases... at least I sure can't get it that high....
Model airplanes are cool too!.....
A tribe in Indonesia (I think, or somewhere around there) use a square box type of tube, a plunger with feathers for a seal, and some vigerous pumps to ignite dry shavings. This is their fire stick!
As a youth I oiled my pumps with motor oil or whatever and have never been able to ignite anything. That was in the 70's when the valves had a rubber tube mechanism needing something like 20lbs to get the air through the valve.
Air rifles are a different story
IF it has rubber parts, I'd recommend a silcon grease. It's often ued as heat sink grease for electronics, valve grease for ceramic/glass containers that hold acids and similar and several other uses that escape me at the moment. OH- Vacuum grease is another.
