Dry
scroll pumps are used for small scale vacuum applications where
there is a need for contamination free "dry" vacuum. Dry scroll
pumps use a tight tolerance, rotating scroll to squeeze gas from the
inlet to another stage or exhaust. There is no oil used anywhere in
this pump. Dry scroll pumps can reach a pressure of 7 x 10
-3
torr at a pumping speed of up to 20 cfm. Dry scroll pumps can be
used for corrosive and oxygen service. Dry scroll pumps are not
recommended for applications where a lot of water vapor is pumped.

The Kinney® Liquid Ring Pump from Tuthill
Vacuum & Blower Systems is a non-pulsating vacuum pump that
removes gases through the use of rotating impeller blades that
enter and leave a ring of liquid. The impeller forces this
sealing liquid to the periphery of the pump casing, where it
forms a moving ring of liquid around a center void. (Click for a

Introducing the
Atlantic Fluidics Liquid Ring Vacuum Pump, featuring the
proprietary Fluid-Vac® axial flow design. This rugged,
compact-design pump generates the highest vacuum of any comparable
liquid ring pump. A fixed port cylinder, concentric with the rotor
bore, directs the gas along the shaft axis, into the suction ports
of the rotor and finally back through the rotor and rear of the pump
for discharge. Because the gas flow is along the motor shaft (and
not at right angles), the pump can start flooded, without damage.
The use of a shrouded rotor increases pumping efficiency for high
vacuum and low water consumption. (Click for a full line of Atlantic
