Welch corrosion-resistant diaphragm vacuum pumps are perfect for alcohol recovery and any other application that involves corrosive vapors. Driven by explosion-proof motors rated for Class I Hazardous Locations (HazLoc), these pumps combine safety and reliability allowing you to focus on processing.
The aluminum pump head is PTFE coated and the diaphragm is covered by a PTFE liner to separate chemical media from the diaphragm.
The explosion-proof motor is directly coupled to the diaphragm pumping module.
Stainless steel tubing is used to connect pump heads together in one and two-stage configurations.
