The discharge from the first stage feeds directly into the second stage, creating a stronger and more continuous vacuum.
This pump design can reach vacuum levels down to 35 mm Hg A, which is around 35% lower than single-stage pumps.
Two-stage pumps offer better efficiency specifically when operating at high vacuum levels, unlike their single-stage counterparts.
Integral two-stage impellers condense vapors efficiently, allowing for recovery or safe disposal within the process.
They are especially suitable for operations involving solvents, where deeper vacuum and stable performance are critical.
