Page 8: Design And Function
The diaphragm vacuum pumps of the series MVP 055-3/3C are three stage and those of the MVP 035-2 series are two stage, dry compressor vacuum pumps. That means that the supplied medium is not brought into contact with lubrication. The pumps are positive displacement pumps with a periodic change of size of the suc- tion chamber produced by the movement of the diaphragm. - Page 9 Product description A1 Vacuum connection 2.1 Exhaust Diaphragm head 1 Diaphragm head 2 Diaphragm head 3 Diaphragm head 4 Mains power supply Power switch Voltage selector switch 28 Hose connection 40 Gas ballast valve Fig. 4: MVP 055-3C...

Installation WARNING Emission of toxic substances from the exhaust! Danger of poisoning from emitted gases or vapours, which can be detrimental to health and/or can pollute the environment, depending on the particular application. Comply with the applicable regulations when working with toxic substances. Only officially approved filter systems may be used to separate out these substances. - Page 12 Installation Switch position: "115" "230" Voltage ranges: 100 ... 120 V, 50/60 Hz 200 ... 240 V, 50/60 Hz Motor protection A self-locking thermal winding protector switches off the pump motor in the event of overheating. Allow the pump to cool off several minutes and do not switch it back on until it has cooled off.

Page 14: Operation
Operation 6 Operation 6.1 Before switching on the pump Compare the voltage information on the rating plate with the mains voltage. Check that the exhaust connection allows free flow (max. permissible pressure 1.1 bar absolute). – Activate the shut-off valves in such a way that they open before or at the same time as the pump is started. - Page 15 Operation WARNING Reactive, explosive or otherwise dangerous mixtures! Uncontrolled gas inlet at the gas ballast valve can result in dangerous mixtures. By implementing the required safety measures, the user must prevent potentially ex- plosive mixtures from occurring in the inside of the pump and from being ignited in the event of a diaphragm crack by mechanically produced sparks, hot surfaces or static electricity.
