APPLICATIONS: Harsh industrial environments requiring protection against corrosion, that contain hazardous gas and vapor, dust fibers, filings or other material that may have explosive properties. These pumps are commonly used for vacuum furnace evacuation, backing turbomolecular pumps, backing diffusion pumps, rotary evaporation, refrigeration system evacuation, epoxy degassing, vacuum sterilization, backing mass spectrometers, freeze drying, vacuum centrifugal applications, vacuum distillation, space research, and other vacuum processes.
NOTE: These explosion proof pumps are designed for environments where risk of building up concentrations of explosive/flammable vapors is high. Typically not required by EH&S for processing standard laboratory solvent vapors. XPRF Motors power cords do NOT have plugs on them, because to meet XPRF system requirements, all components must be XPRF, be sparkless, and power conduits must be wired to hermetically sealed electric junction boxes by a qualified electrician. If any component in the system, vacuum oven, freeze dryer, etc is NOT XPRF then you do not have an XPRF system. It is recommended that you consult with their EH&S department and decide if XPRF is indeed appropriate, or if choosing an alternative Welch vacuum pump makes more sense. Ideal Vacuum Products cannot recommend for or against use of XPRF motored vacuum pumps. That decision must remain the responsibility of each customer.
