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.
The diaphragm pump MPC 301 E is a two-stage pump. It is compact and functional. Maintenance and service are quick and easy to carry out. The pump operates extremely quietly.
The diaphragm pump MPC 301 E is designed for:
Conveying and compressing neutral and aggressive gases and vapors
Generation of vacuum up to an ultimate pressure <5 mbar
Use in physical and chemical laboratories
