The GV series are specifically designed for your demanding industrial applications offering consistent and repeatable performance. Its ability to operate continuously at high-pressure levels makes it the most cost-effective introduction to dry pumping.
Packaged into two products, the GV80 and GV110, these pumps are designed to handle large volumes of condensable vapours and particulate loads for a consistent pumping performance you can rely on, with minimal service intervention and a low cost of ownership.

Better vacuum levels result in better end-product quality for many customers thanks to lower contamination levels and/or lower product processing temperatures that help preserve the properties of the raw material.
Repeatable vacuum performance is desirable for any production environment. Factors like oil/water temperature or condition, that are necessary in oil-sealed and liquid ring vacuum pumps as a sealant for the compression mechanism, do not affect dry running vacuum pumps.
GV pumps are based on Edwards' oil-free, non-contacting, award-winning, reverse claw mechanism technology. This robust mechanism has been specifically designed to provide stable operation for heavy-duty applications even with variable process conditions. It has been tried, tested and proven by the industry over thousands of chemical, pharmaceutical and petrochemical installations worldwide and represent the dry vacuum pump standard for many customers worldwide.
The GV Series achieve very low noise and vibration levels, which is a benefit to the surrounding environment, in addition to occupying a very reduced footprint. Its motor size allows for sufficient power during start-up and becomes very efficient at low pressures, and the stand-by mode allows to keep the pump running between process batches with power consumptions below 1kW even with the booster combination, while using minimal cooling water and purge gas.
The GV110 vacuum pump includes all the features of the GV80 and offers additional features including an integrated variable speed drive technology to meet process demand, modern acoustic enclosure for a quieter operation and improved pumping performance that is able to operate continuously at high-pressure levels.
Standard configured packages are available based on the GV offering additional features, the Drystar®. These standard options are available as a pump only option or combined with the EH500 hydrokinetic drive mechanical booster offering 500m3/h for applications where increased pumping speed and/or lower vacuum levels are required.
The GV series vacuum pumps help reduce the environmental footprint generated by vacuum pumps. In comparison to oil-sealed or liquid-ring vacuum pumps, the pump does not result in waste oil generation and treatment nor in a contaminated water effluent respectively. In addition to this, dry pumps enable the recovery of uncontaminated and many times valuable process gases.
To ensure your GV110 and GV80 pump and system maintains optimal performance and reliability, we offer a wide range of service solutions, tailored to meet your needs. From Field Service intervention to Managed Maintenance agreements, we will take care of your pump to ensure that it continues to deliver clean, consistent, efficient performance, with lower running cost and optimum total cost of ownership for its entire operating life.
Drystar80 is the most cost effective introduction to basic dry pumping. It is available as a standalone unit for 80 m³/h repeatable pumping performance; or in a combination with the respected EH500 hydrokinetic drive mechanical booster, offering 500 m³/h 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.
Product Features
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
improved life.
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
performance.
