ChemStar

DUOSEAL vacuum pumps are known for their durability and reliability.  


Two-stage models include 1400, 1405, 1402, 1376, 1397 and 1374 and can reach 1x10-4 Torr. The free air displacement ranges from 0.9 cfm to 23 cfm. 


One-stage models include 1399 and 1380. Free air displacement ranges from 1.2 cfm to 5.6 cfm.


The key features of DUSOSEAL pumps are:



  • The low pump rpm reduces friction and wear while minimizing reservoir temperature to lessen chemical activity.

  • All models have large oil reservoirs to dilute contaminants.  

  • The oil feed is located high so the cleanest oil enters the pump model.


Applications: Freeze dryers, vacuum ovens, schlenk lines, glove boxes, degassing chambers, altitude chambers, high boiling point distillation systems, HVAC servicing.
