Pumping Speed

Exhaust speed of the Oil rotary pump shall vary depending on the type and pressure of the sucked

gas. It shall indicate the maximum exhaust speed in the high pressure range and lower speed little by
little lower becomes the pressure.

PVD-180-H, -360-H has no gas ballast valve. Refer to contents of “Gas Ballast Closed”.
