Just a question. If I have a liquid with low superficial tension, does it wet the metal less the metal than ones that has an high superficial tension?

I thank you for your interest, but I can't give you more details. However I have 5 months for working about this problem.

this is the problem, my question is 'is another gas able to improve the test reliability?' the test in working condition is not just dirty but it also very slow

We discard many components. after the dry test if we test the discarded pumps in working condition we find that many of them are good. So we thought to find an alternative fluid

This is what we are doing now with air. But it gives us much problems. The test is too much selective. We call it 'dry test'. no one lubricant is used during the test

what about the oiliness of glycerol? After the test the pump has to be clean, without 'any drop' of liquid again thanks

I know it, now we are testing the pumps with air, as our competitors also do, because the test is fast, economic and clean. But, clearly, we have some problems with this test. For this I thought also to a heavy gas.

I have to estimate the leakages of a volumetric pump. I excluded the water for the corrosion of metal. The test must be made on every component that has to go to the client, therefore the test has not to damage the pump thanks Giuseppe

Hi, I am a mechanical engineer, therefore I am no very experienced in chemistry I need to find a fluid similar to lubrificant oil in density and viscosity, but with low oiliness I thought to gasoline, but it is very dangerous for my aim. I have to test on the production line some components...
