A pneumatically actuated vacuum pump is disclosed, and includes a body defining a converging motive section, a diverging discharge section, at least one suction port, and a Venturi gap. The Venturi gap is located between an outlet end of the converging motive section and an inlet end of the diverging discharge section. The pneumatically actuated vacuum pump also includes a first check valve fluidly connected to the Venturi gap and the suction port. The pneumatically actuated vacuum pump further includes at least one second gap located in the diverging discharge section of the body downstream of the Venturi gap. A second check valve is fluidly connected to the second gap.
