Dry running vacuum p





       The compact system SIHIdry  is a dry running, screw-spindle pump. The screw shaped rotors counter rotate without contact. The pump inlet is at the top and the outlet at the bottom. This gives top-down pumping for self-draining.
In contrast to conventional machines, both spindles are synchronised electronically and do not need a mechanical gearbox.
This innovative drive concept provides the foundation for allowing the basic unit to be transformed into more intelligent versions for integration within any process control system. This intelligent version of the SIHIdry H250 is able to operate system attributes such as reactor pressure; valve functionality, etc. The data can also be stored and downloaded in order to facilitate good manufacturing practice.
