Get the Edwards dry advantage
Maximise your productivity and performance
Edwards has the largest installed base of dry vacuum pumps in the world. Edwards’ dry claw vacuum pumps are built to the exacting standards and quality demanded by our customers. The technology is packaged into two products, the GV80 and GV110, offering many key advantages for industrial applications.
Both products offer a trouble-free and cost-effective solution to meet your needs, and offer the following advantages:
The GV110 is the latest industrial dry claw vacuum pump from Edwards. Building on the advantages of the GV80, the product offers additional features and benefits including an integrated variable speed drive, modern acoustic enclosure and improved pumping performance. Like the GV80, the new product offers consistent pumping performance, minimal service intervention and low cost of ownership for a variety of industrial applications.
Robust:Continuous operation with the ability to handle large volumes of condensable vapors.
Consistentoutput:Providing delivery of repeatable pumping performance.
Enviroment friendly:Eliminating frequent oil changes and waste oil disposal.
Reliable:High tolerance of process dust and particles
Low cost of ownership:With clean, quiet pumping and minimal service disruption.
Industry proven, tried and tested:Specifically designed for demanding industrial applications.

Drystar® GV80 and EH500 booster configured packages
Standard configured packages are available based on the GV80 offering additional features, the Drystar® GV80. These standard options are available as a pump only option or combined with the EH500 hydrokinetic drive mechanical booster offering 500m3h-1 for applications where increased pumping speed and/or lower vacuum levels are required. For further details please contact your Edwards representative.
Drystar80 is the most cost effective introduction to basic dry pumping. It is available as a standalone unit for 80 m3/h or in a combination with the respected EH500 mechanical booster for 500m3/h and lower vacuum levels

Drystar80 is the most cost effective introduction to basic dry pumping. It is available as a standalone unit for 80 m3 h-1 repeatable pumping performance; or in a combination with the respected EH500 hydrokinetic drive mechanical booster, offering 500 m3 h-1 displacement for applications where increased pumping speed and/or lower vacuum levels are required.
Depending upon the application the Drystar80 can be supplied with mineral oil or PFPE lubrication.
DOUBLE-ENDED SHAFT SUPPORT
Non-cantilever design provides secure rotor support for extremely low vibration and superior starting reliability, especially on harsh processes. Superior liquid and powder handling.
BEARING AND LUBRICATION
Oil lubricated gears eliminate grease and the need for periodic maintenance. Uses advanced quality bearings and special
purpose oil with low vapour pressure for
application compatibility and greatly
ADVANCED SHAFT SEAL TECHNOLOGY
Non-contacting long-life seals with integral oil blocking labyrinth seal provides for highly effective sealing. Combined with a six litre per minute seal purge the gearbox is protected from contamination and the vacuum space is kept free of oil.
MOTOR AND DRIVE TECHNOLOGY
Extremely high efficiency motors with
electronic drives deliver maximum torque
performance for difficult Processes. Hermetically sealed motor eliminates oil leaks and improves pump reliability. Water-cooled motors and drives provide for improved reliability and long life to reduce service costs.
ROOTS BOOSTER MECHANISM
High efficiency vacuum booster design. Optimised for maximum performance with automatic thermal management.
ADVANCED MECHANISM DESIGN
Enhanced screw-type rotor design results in smooth, gradual compression along the length of the rotor for improved thermal control and optimised pumping at all inlet pressures. Advanced machining techniques and design features eliminate the need for rotor coatings while maintaining superb ultimate vacuum
