GXS250

Edwards, a pioneer in dry pumping technology, launches a new generation of dry pumps for industrial applications.
 
Edwards has over 90 years of experience in harsh process vacuum applications, including dust and process contaminants handling, with more than 150,000 dry pumps installed worldwide.
 
The GXS industrial dry screw pump incorporates innovative, patented design features that establish a new standard in dry pumping.
 
This pump offers the following specification and is suitable for the Light duty:

• Low Voltage 200-230 V 3Ø 50/60 Hz
• Side Exhaust and Skids installation type
• Shaft Seal Purge

Features and Benefits
Designed for high reliability
Edwards patented screw-rotor design delivers excellent pumping-speed and is part of an advanced thermal management system that maximises pump performance and life of the seals, bearings and motor to ensure long pump service life.
 
Adaptable to a wide range of applications
GXS pumps may be supplied either alone, or with a high speed Roots booster to economically increase their capacity and ultimate vacuum.  In addition, Edwards offers a range of purge options, filters, catchpots, inlet isolation valves and silencers; which together with our special high flow purge and solvent flush accessory enabling the inside of the pump to be kept clean without disassembly.
 
Long service interval and easy swap-out
Long-life non-oxidising gearbox oil enables service intervals of up to 5 years to be achieved.  Quick-connect utility interfaces provide for rapid pump installation and exchange to improve factory up-time.
 
Low cost of ownership
Custom high-efficiency motor and drive system with advanced seal technology gives greatly reduced power consumption.  Minimal cooling water and purge gas requirements coupled with improved powertrain technology enables long service intervals and near maintenance-free operation to be achieved.
 
Minimum workplace and environmental impact
GXS pumps are incredibly compact.  Edwards advanced screw-rotor design provides for remarkably quiet, low vibration operation even without a silencer.
 
Simple to install and operate
GXS pumps are easily wheeled or fork-lifted into position, coupled to the process and services using the supplied mating connectors and run at the push of a button.
 
Ideal for integration into larger systems
GXS pumps and combinations are supplied with serial (RS232) communication and LAN-based webserving capability as standard.  Optional modules are available to add Parallel (digital I/O) and Profibus control functionality.
