The MAPRO® vacuum pumps, FPS series, ranging from 3.5 to 20.5
m3/h, are oil-free rotary vane machines. The blades of these
pumps are in fact made of special graphite which allows them to
operate without any lubrication.
The operating principle of the FPS pumps is the same of the BV
pumps, but the ultimate vacuum of the FPS pumps is much lower
than that of the BV pumps.
In fact the clearances inside the machine body are not
closed by the lubricating oil, thus allowing the
recycling of air between the discharge and the
suction areas of the vacuum pump.
Moreover the use of the FPS pumps is not
recommended when the air to be sucked contains
water vapour or oil vapours.
And yet the FPS pumps can operate continuously at any
vacuum between the atmospheric pressure and their
ultimate vacuum. Moreover, their maintenance is
extremely simple and limited to the periodic
replacement of the blades.
The main industrial sectors where the FPS pumps
can be used are, for instance, those of the handling
by suction cups, of the packaging machinery, of the
The standard construction is easy and compact as all the models
are manufactured in the so-called close coupled version.
The vacuum pumps, FPS Series, meet the requirements of the
European Directives 2006/42 (Machines), 2006/95 (Low Voltage),
2004/108 (Electromagnetic Compatibility) and of the applicable
