Water pump FTP series

polymeroilelectric

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; and 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.
