Cps pump misting oil

Yes. It is part of the design of the pump. You need to run a catcher. Or you need to get the CPS that has this feature. I am not sure they all do.

Yes, after reading more about this, the CPS, despite the claim, do mist up pretty well.
We will see soon enough. The pump will be here next week.

I found this, if the problem is very bad, but the oil collectors have limitations, too.

When choosing an oil mist eliminator, the following should be considered and determined.

1.) Volume and capacity of oil mist: Oil mist eliminators have limitations as to how much gas can flow through them. Exceeding the rated or design limits of an oil mist eliminator is not recommended. Selecting or designing a oil mist eliminator for up to 3 time the expected run or operating capacity is recommend:

2.) Oil mist produced by a machine often contains more than oil but it also contains many other contaminants and harmful chemicals. Additional features that prevent exhaust of these contaminants should be included.

3) Consider the maintainability of any oil mist eliminator. Systems that require a new paper filter, or excessive routine maintenance should be avoided. Keep in mind that a low maintenance system may actually be more expensive, but costs less over the like cycle of the machine.

We had to use demisters on the exhaust of all of our larger industrial vacuum pumps, especially those with oil diffusion pumps before them, to keep pools of oil off the roof, but a CPS just makes more of a mess that a pad soaks up or wipes off the pump itself.

With a little ingenuity, you can attach a hose to send the exhaust to a handier place, which is a good idea anyway if cold boiling and the oven and pump is in a confined space.
