- 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
