EXS750

Get the Edwards dry advantage with the new EXS750

Our new EXS dry pumps take our industry proven screw vacuum technology to the next level. Based around the same technology that we use in our GXS pumps, the EXS has been designed to bring the advantages of our market leading technology in a package that focusses on simplicity and robustness. With more performance, simple control philosophy and low maintenance costs the EXS will deliver reliable performance for many years to come.

FAST – Increased roughing speeds and low ultimate performance

Increased productivity: faster processing and pump down times

Low ultimate pressures <1 x 10-2

 

ROBUST – Reliable operation even in harsh industrial applications

Low maintenance cost: no unplanned down-time

Increased productivity: longer intervals between service

 

PROVEN – Based on existing GXS technology

Huge install base: on hundreds of applications

Optimised design: enables enhanced performance

 

ECONOMICAL – Affordable capital investment and low cost of ownership

Substantial savings: low utilities and energy usage costs

Save on space: small footprint

 

ENVIRONMENTAL – Smooth, quiet running with low power and utilities consumption

Small carbon footprint: low power and utilities usage

Easy on environment: no contaminated or dirty disposable oil

 


Simple Electrical Strategy

In-built off-shelf inverter for simple connection and communication.  

Electrical cabinet designed according to IP54 requirements.

Basic control philosophy for ease of installation and operation.

 

Robust Design Features

Reliable constant flow cooling system.

Dependable new gas system with manual gas ballast control.

Sleek sheet metal protective enclosure.

 

Advanced Core technology

Non-contacting long-life seals with integral oil blocking labyrinth seal

provides 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.

Industry proven on 100s of applications.

Uses advanced quality bearings and special purpose oil with low vapour

pressure for application compatibility and improved service life.

Non-cantilever design provides secure rotor support for extremely low

vibration and superior starting reliability, especially on harsh processes.

Superior liquid and powder handling thanks to a sealing solution that is

industry proven in 100s of applications.

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.
