Features and 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.
