Easy on environment: no contaminated or dirty disposable oil

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.

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.

EXS Pump features and innovative screw technology.
