Welch ChemStar 1400N 0.9 cfm 0.1 Micron Belt Drive 2-Stage Pump

The Welch 1400N ChemStar 0.9 cfm 0.1 Micron Belt Drive Rotary Vane Pump is specifically designed to handle harsh chemical environments, offering superior corrosion resistance and excellent vapor handling capabilities. This pump is ideal for laboratories and industrial processes that require protection from chemical contamination, thanks to its PTFE-coated oil case, corrosion-resistant parts, and nitrogen bubbler feature.

Key Features:

• Corrosion-Resistant PTFE Coated Oil Case: Prevents contamination and ensures cleaner oil by avoiding polymerization reactions from aggressive chemicals.
• Nitrogen Purge System: Allows nitrogen to blow through the oil case while processing extremely corrosive gases, cooling and degassing the oil.
• Low Rotational Speed: The 580 rpm motor reduces friction, wear, and operating temperature, extending the service life of the pump and minimizing chemical reactivity.
• Superior Chemical Resistance: PTFE-lined oil case, fluorocarbon gaskets, and seals provide resistance to harsh chemicals, protecting vital parts from corrosion.
• Gold Oil Lubricant: The synthetic lubricant minimizes the effects of chemical contamination, ensuring the longevity of the pump.
