What is Backstreaming?
To stop oil backstreaming in your vacuum pump system we first need to understand how it happens. Backstreaming occurs when the oil vapor flows from the mechanical pump into the vacuum system. This can contaminate your process or product, result in unwanted downtime and can be an expensive repair.
Factors That Can Result in Backstreaming:
- Operating vacuum pump continuously at deep vacuum levels (near base pressure of the pump)
- Using low-grade vacuum pump oils
- Not changing contaminated oil
- High pump operating temperatures
