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.
