Chem-Dry pumps
use no fluids for seal-
ing, eliminating the possibility of their
contaminating your process or causing
downstream pollution. You get a purer
process and end product and save on
waste disposal, fluids, and labor.

Chem-Dry
Applications
●Vacuum Distillation and Solvent
Stripping - excellent for solvent recovery
● Pharmaceutical Production -
recovery of solvents, collection of
intermediates
● Pilot Vacuum Processes - differen-
tial condensation, recovery of high-
boiling intermediates
● Flavors and Fragrances - enhanced
recovery of essential oils, terpinoids,
and complex flavor concentrates
● Medical Device Fabrication - clean,
sterilizable vacuum pump for
implantable device manufacture.
Recovery of ethylene oxide gas
sterilants
● Materials Research - pump aggres-
sive gases safely at high flows and
concentrations
● Fatty Acid Production - elimination
of water pollution and drain blockage
from ejector effluents

Sizing: Stokes Vacuum Dry Pumps are staged
dry lobed mechanical pumps. They develop base
pressures to 1 torr or better and are available in a
wide range of sizes. Because the pumps are true
dry backing pumps, they can be employed with
rotary lobed blowers for more speed and lower
pressure (0.03 torr typically).

The New Chem-Dry
Eagle Series pumps are ultra compact and need no inter-stage heat
exchangers, drain tanks, or external pipling. Plus they can run hot
or cold and handle wet acids. All models use two parallel single-piece
tri-lobe rotors, gear driven with precision bearings.
