Diaphragm pump for dry and clean vacuum

As diaphragm pumps are oil-free, they are suit­able for all work and numer­ous appli­ca­tions where a clean, dry vac­u­um is required. Exam­ples include lab­o­ra­to­ries, ana­lyt­ics, leak detec­tion and research & devel­op­ment. With the MVP 030–3 C DC, Pfeif­fer Vac­u­um has brought a cor­ro­sive gas ver­sion of the diaphragm pumps onto the mar­ket. This ver­sion fea­tures a gas bal­last valve and good chem­i­cal and con­den­sate com­pat­i­bil­i­ty. The choice of mate­ri­als ensures robust­ness in a wide range of processes.

Diaphragm pumps not only do their job reli­ably, but also qui­et­ly and with low vibra­tion. The noise lev­el is below 45 dB(A). Due to their com­pact design and low weight, they fit into small analy­sis sys­tems, mass spec­trom­e­ters and tur­bo pump­ing sta­tions. Due to the mutu­al con­trol­la­bil­i­ty, intel­li­gent oper­at­ing states can be para­me­terised. This reduces pow­er con­sump­tion and wear. Diaphragm pump and tur­bop­ump can be con­trolled via a sin­gle Pfeif­fer Vac­u­um oper­at­ing unit and are sup­plied with pow­er via a com­mon cable. This results in less cabling and low­er costs.

The brush­less DC dri­ve sys­tem allows the speed to be adapt­ed to the require­ments of the respec­tive appli­ca­tion. In auto­mat­ic boost mode, the pump starts at over­speed. This can short­en the ramp-up times of the con­nect­ed sys­tems, enabling users to com­mis­sion the sys­tems more quick­ly. The speed is reduced as soon as a cer­tain vac­u­um is reached or a cer­tain time inter­val has elapsed. This brings more effi­cien­cy and long main­te­nance intervals.

In addi­tion, the diaphragm pump series achieves high ener­gy effi­cien­cy through stand­by and pos­si­ble inter­val oper­a­tion togeth­er with tur­bop­umps. The 24 V DC pow­er sup­ply means that the elec­tri­cal design and asso­ci­at­ed safe­ty mea­sures are less com­plex, which fur­ther reduces costs. The three-stage MVP 030–3 C DC is equipped with a man­u­al gas bal­last valve. Pos­si­ble con­den­sate build-up in the diaphragm pump can be pre­vent­ed by open­ing the gas bal­last valve. This leads to high­er process reli­a­bil­i­ty and a longer ser­vice life. Added to this is the uncom­pli­cat­ed main­te­nance of the diaphragm pump. Both the diaphragm and the valves can be replaced eas­i­ly and in a time-sav­ing man­ner. The DC dri­ve ensures that the pump can be used worldwide.
