Rotary vane vacuum pump

oil-freesingle-stage

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 woodworking machines. 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 harmonized Standards.
