High pressure pump, method of operating a high pressure pump and homogenizer

摘要

A high-pressure pump (1), preferably for working pressures 100 bar, for conveying a fluid (20), in particular a wax / resin dispersion, has a plunger (6) arranged in a housing (2), one through the plunger (6) , a suction valve (8) and a pressure valve (9) delimited working space (7), a high pressure seal (10) surrounding the plunger (6), a first inlet (11) connected to the working space (7), through which a continuous phase and a first fluid (20) having a disperse phase can be fed to the working chamber (7), a first outlet (12) provided on a pump head (3) for discharging the first fluid (20) under high pressure, one on one of the working chamber (7) ) on the opposite side of the high pressure seal (10) provided a second inlet (13) for supplying a second fluid (19) and a second outlet (14) for discharging the second fluid (19) from the housing (2), the second outlet (14 ) for admixing the second fluid (19) as con continuous phase of the first fluid (20) is connected to the first inlet (11). Furthermore, a method for operating such a high-pressure pump (1) and a homogenizer are described.
