Built for Hazardous Environments. No Compromises
If you're servicing refrigeration systems in environments where flammable chemicals or vapors are present, standard vacuum pumps aren't an option. Welch’s Explosion-Proof Chemical Duty Diaphragm Pumps are engineered for these exact conditions. They meet NEC Class I, Division 1 Group C&D standards, meaning they’re safe to operate in areas with acetone, benzene, butane, propane, and similar volatile compounds.
These pumps are oil-free, corrosion-resistant, and built to handle aggressive vapors without risk of ignition. They’re ideal for technicians working in labs, industrial facilities, or field service where safety and chemical compatibility are non-negotiable.
