Welch corrosion-resistant diaphragm vacuum pumps are driven by explosion-proof motors rated for Class I Hazardous Locations (HazLoc). The aluminum pump head is PTFE coated and 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.
The vacuum pump doesn’t come with an on/off switch, plug or cord, but must be conduit wired to the on/off explosion proof control panel. Always use a certified electrician for proper installation of vacuum pump with explosion proof motor to meet your local municipal codes.
- Flow from 4.5 to 6.9 cfm
- Maximum vacuum to 29 in. Hg (25 Torr)
