Operating Principle of TRIVAC Two-Stage Pumps:
TRIVAC pumps work according to the two-stage rotary vane principle: Gas passes through two pumping stages sequentially in a common housing. The first stage (high vacuum stage) draws in the gas and compresses it to an intermediate pressure. The second stage (backing stage) takes the pre-compressed gas and discharges it against atmospheric pressure. This two-stage arrangement enables significantly deeper ultimate vacuum than single-stage pumps.
