Chemical dry pumps
Edwards is a market leader in dry pump technology and pioneer of
dry vacuum for the chemical process, pharmaceutical and fine
chemical industries. The CDX uses the very latest in screw pumping
technology, whilst the EDP range utilizes the reverse claw
mechanism, proven over more than 20 years and in over 100,000
installations worldwide, to provide a clean and robust vacuum
solution.
Why dry?
Dry running pumps have no oil, steam or water in the process volume.
This eliminates, at source, the pollution traditionally associated with
wet sealed vacuum systems and provides cost and materials
handling benefits as the sealing medium does not have to be
replenished:
•
•
•
•
•
no contamination of the process stream
no polluted effluent
no messy oil drums
improved processing with reduced down time
lower utility and consumable costs
The product range is available from 80 m3h-1 / 47 ft3min-1 to
1000 m3h-1 590 ft3min-1 with capacity expandable to 30000 m3h-1 /
17660 ft3min-1 and an ultimate pressure of better than 10-2 mbar /
0.015 Torr using combinations of mechanical vacuum boosters.
Applications Engineering is a core competence and Edwards are able
to offer a comprehensive solutions package that includes:
•
•
•
•
•
Process design
Equipment specification and selection
Safety and operating procedures
Vacuum system and control integration
Commissioning advice
Edwards have a full range of dry pumps with a set of characteristics
suited to most applications.
EDP Series A vertical claw pump with indirect cooling and
temperature control - ideally suited to applications where there is the
likelihood of liquid carry over, where cooling water is likely to be of low
quality, or where close temperature control of the pump is required.
CPH Series A horizontal claw pump for applications with a low risk of
significant liquid carry over, and where temperature control of the
pump is not critical.
CDX A large capacity dry pump for applications where high speed
pumping is required from atmosphere down to process pressures.
Chem-Dry CD Series A range of multi-stage roots pumps for
applications where high vapor loads require to be condensed out
between pump stages.

The proven and rugged non contacting designs, both screw and
reverse claw mechanisms, include the ability to control pump body
and internal gas temperatures allowing a comprehensive range of
solvents, flammables and corrosives to be pumped. Systemized
variants address the EU's explosive atmospheres (ATEX) directive
for Category (Zone 0) T4 operation. The mechanisms are both highly
tolerant to liquids and particles in the gas stream and are suitable for
many applications, including:

Reversed claw
The reverse claw mechanism
The EDP and CPH range are multistage claw mechanisms. Each
stage comprises of two claw shaped rotors on parallel shafts, which
rotate in opposite directions. The claws trap and compress the
process gas, which takes a zig-zag path between the stages, as it is
moved along the axis of the shaft from the inlet at the top to the
exhaust at the bottom.
PROCESS EXHAUST
P&ID example: Typical dry pump system with mechanical booster
and seal purge options
Accessory modules offered include:
Mechanical boosters
Provide increased pumping speed & improved ultimate. Available
with:
• Hydrokinetic drive for faster pumpdown
• Rotation sensors

• Inlet purge*
• Shaft seal purge*
Safety
Edwards offer a comprehensive range of solutions to containment
and constructional safety, to satisfy ATEX or your own requirements.
D
• Flame arrestors
• Solvent flush*
• Inlet isolation valves*
C
Vessels
Solvents and other liquids carried over in the process stream can be
recovered upstream or downstream of the pump.

Used to dilute flammables and improve seal life
Outlet isolated
Outlet isolated
During each complete rotation of the claws, first the inlet port of each
pair is exposed (to admit gas to the pump), then both the inlet and
outlet are isolated (to trap and compress the gas) and finally the outlet
is exposed (to expel the compressed gas).
• Knock-out pot*
• Condenser*
• Receiver*
Acoustics
Silencers reduce pulsations in the exhaust and hence noise in the
exhaust line. All silencers are drainable.
• Silencers
Monitoring & control
Offerings range from gauges and simple 4-20 mA transmitters to fully
enclosed bespoke control units.
