These Stokes pumps are designed for vacuum processes which require bank-off in the low-micron range. They consist of a field-serviceable direct-drive Stokes Microvac rotary piston pump (page 3). Several models are designed to pump directy from atmosphere. Others are equipped with a pressure switch which automatically starts the blower at a specified cut-in pressure. All operate at high speeds and low pressures (even with full gas ballast), and provide excellent water-handing capacity.
