Diaphragm Compressor: Neuman & Esser

NEA|HOFER MKZ diaphragm compressors provide a lubricant and technical abrasion-free compression of gases and gas mixtures. As they operate leakage-free, they are particularly suitable for high-purity applications and for use with explosive, toxic and expensive gases. Our diaphragm compressors are suitable for compressing hydrogen, helium, argon, ethylene, fluorine, hydrogen sulfide, chlorine, monosilane, or nitrogen trifluoride.

Our diaphragm compressors are typically used, for example, for filling storage tanks, for feeding into continuous processes or as circulating gas compressors. They are characterized by their design specifications, which make the machines particularly safe, reliable, and easy to maintain. We generally provide our diaphragm compressors as complete systems with base frame, drive, pulsation dampers, coolers, fittings (automatic or manual), instruments and controls (optional). However, we also offer diaphragm compressors without auxiliary equipment for installation in your system. Every NEA|HOFER MKZ diaphragm compressor completes a test run under load at our factory, during which the operating data is recorded and documented.

Features at a Glance

oil-free compression due to hermetic separation between gas and oil chamber
technical abrasion-free compression due to static seals in the gas stream
leakage rates of 10^-4 mbar l/sec (on request up to 10^-6 mbar l/sec)
purge or buffer gas is not required
long service life because of a hydraulically actuated diaphragm, no mechanical linkage
good cooling due to the large surface of the diaphragm head
cooling coil in the oil chamber of the diaphragm head, no weakening of the cover caused by cooling channels
automatic shutdown in case of a diaphragm failure prevents consequential damage
discharge pressure up to 43,511 psi (3,000 bar)
stage pressure ratios up to 7
up to 4 stages at a crank drive
mass compensation for foundation-free installation
wear resistant and smooth operation due to low piston speeds
water cooling provides the best cooling effect as well as a low sound pressure level
manufactured in compliance with 2006/42/EC EC-Machinery Directive. Applied standards: DIN EN 1012 part 1, DIN EN 12100 part 1, DIN EN 60204 part 1 et al.
explosion proof according to the European Directive 2014/34/EU, if necessary
