General description

220V models are CE compliant.
ChemStar vacuum pumps are distinguished by having all five of the defining features needed for pumping corrosive gases.
  • High contamination tolerance: large oil reservoir dilutes contaminants
  • Corrosion resistant parts: Viton®, PTFE, stainless steel, nickel-plated or anodized parts
  • Reduced frictional wear: runs at less than 580 rpm versus 1,700 rpm for direct-drive pumps
  • Nitrogen purge standard: degasses and cools pump oil reducing corrosion
  • Easy attachment of accessories: trap and oil mist eliminator
Supplied with 2 pin plug
