WELCH 2027,Self-Cleaning Dry Vacuum System w/Digital gauge, 35 lpm, 2 Torr, 115V 60Hz 1Ph

Diaphragm pumps for chemical applications - type MPC - are chemically compatible and resistant to aggressive solvents and acid vapors which are common in laboratories. The diaphragms are made out of PTFE. The pump and connection heads are carbon fiber reinforced. Their electrical conductivity prevents electrostatic charging and minimizes the risk of gas mixture igniting inside of the pump
