Overview:

The competitive nature of today’s business means changes are required to improve performance, lower costs, and provide optimal process solutions. The dry pumping solution is the change from traditional oil sealed pumps to a proven technology for this industry. Edwards, a world leader in dry pump technology, has demonstrated the ability to provide a low-cost, tailored solution to your vacuum application.

Features & Benefits:
Maintenance
- Low capital cost and minimal maintenance requirements lead to lowest cost of ownership.
- Extended periods between user intervention.
- Lower consumable costs.

Environmental
- No oil disposal.
- No oil emissions into atmosphere.

Performance
- Very stable pumping speed gives repeatability to processes.
- Continuous pumping at atmosphere.
- Ability to handle particulates.
- Dry eliminates back-streaming, thus protecting reactive alloys from contamination.

Safety
- Unobtrusive noise levels.
- No unsightly oil spills.
- No hazardous oil vapours.
