The Absolutely Oil Free Difference
For more than 10 years Vacuum Research Absolute Dry Pumps have set the standard for absolutely oil-free roughing pumps. The Absolute Dry Pumps offer low cost of installation, low cost of ownership, and the most reliable performance of any dry pumps available for use in clean vacuum systems.
Lowest Cost of Ownership
The Absolute Pumps initially cost less than most oil-free pumps, plus they are less costly to install. Auxiliary equipment such as traps and exhaust filters are unnecessary. There are no purge gas or cooling water lines to install. The Absolute pumps are easy to connect to your system with simple KF inlet and outlet flanges. And to maximize your work space you have the option of mounting the pumps in any plane. They can be mounted on the wall, on the floor, or standing on end. Electrical power is all that is required to put the Absolute Dry Pump into service in your system.
Ownership costs are low because with no oil or fluid to check the Vacuum Research pumps require no costly maintenance. In fact, Vacuum Research pumps have a proven life expectancy of more than 10,000 hours for the direct drive models and 20,000 hours for the belt drive models. Oil level monitoring and the frequent oil addition and replacement tasks needed in other pumps are eliminated. There are no costs for disposal and handling of waste oils either.
Constructed for Long Life
Most importantly, the unique construction of these pumps allows for long and reliable service life. All sealing surfaces in Vacuum Research pumps are made of composite non-metallic materials which allow them to function without any oil or fluids for sealing or lubricating. No fluids means total elimination of backstreaming found in rotary vane and pseudo dry pumps.
24 Hour Replacement
Although our oil-free pump requires no regular maintenance and has a longer-than-normal life, there will be times when the units need reconditioning. When this happens, exchange replacement pumps with the same specifications as new pumps are quickly available from our service centers in the United States, Japan, and Europe.
Absolutely No Maintenance
No fluids to buy, check or discard. No traps or filters to service. These features improve uptime and productivity by eliminating the need for regular maintenance. In fact, the proven reciprocating piston design typically provides more than 20,000 hours for belt drive pumps and 10,000 hours for direct drive pumps before any service is needed.
