Class leading performance Low Vibration Maintenance free Guaranteed reliability

Proven magnetic bearing technology


The rotor is entirely suspended by magnetic bearings so all contact between the rotor and the remainder of the pump is eliminated. As well as giving very low vibration, the elimination of contact means no bearing wear and no requirement for consequent pump maintenance.

Key Features:

Multi-axis magnetic bearing system
High Throughput versions for high flow processes
Low vibration characteristics
Advanced controller technology
Full interfacing capability

Features and Benefits:

Improved pumping performance
    - Maximised gas throughput for each flange size
    - Application specific models
New generation controllers
Compact (1/2 rack) controller
   - Auto tune enabling "mix and match"
   - Integrated TMS controller
   - Improved diagnostics
High power d.c. motor drive
