A range of products ATEX certificated to directive 94/9/E requirements The FTP gear pump from Marzocchi is an ideal solution for low-pressure lubrication applications where low-viscosity fluids are required, such as fire-resistant ones. Typical applications include large lubrication systems, lubrication of the guides of machine tools, and the lubrication and cooling of the tools themselves. There are several types of fire-resistant fluids and they are generally classified as follows: oil and water emulsions, water-polymer solutions, and anhydrous synthetics. More specifically, the International Standards Organization (ISO) further classifies these fluids as follows: HFAE: oil-in-water emulsions, typically with more than 80% water content; HFAS: synthetic aqueous fluids, typically with more than 80% water content; HFB: water-in-oil emulsions, typically with more than 40% water content; HFC: water polymer solutions, typically with more than 35% water content (also known as glycol solutions, polyalkylene glycol solutions or water glycols); HFDR*: synthetic anhydrous fluids composed of phosphate esters; HFDU: synthetic anhydrous fluids other than phosphate esters. Examples include polyol esters and polyalkylene glycols. *The only fire-resistant fluids that are completely incompatible with gear pumps are the HFDR ones; for all the others it is possible to obtain a configuration that makes them compatible. Marzocchi FTP pumps are based on ELIKA Gear Technology that reduces the noise level by an average of 15 dBA compared with a conventional external gear pump. The helical gears ensure the continuity of motion despite the low number of teeth. FTP pumps are perfectly interchangeable with standard gear pumps. The low number of teeth reduces the fundamental frequencies of the pump noise, therefore lowering sound levels. The shape of the Elika profile, patented by Marzocchi Pompe, eliminates the encapsulation phenomenon typical of standard gear pumps, remedying the source of the main cause of noise and vibrations. By reducing the pressure-oscillations and vibrations produced by the pump and transmitted to the other components, the noise of the hydraulic system itself is reduced. Specific compensation areas in the flange and cover, insulated by special gaskets reinforced with anti-extrusion, allow for fully free axial and radial movement of the bushings.
