Liquid ring vacuum pump in ceramic

Keramik-Pumpe FGP
FGP Keramik-Pumpe
FGP Flüssigkeitsring-Vakuumpumpe

Our FGP liquid ring pump is the suitable partner for difficult evacuation and  compression processes involving gases and vapours in all corrosion-critical areas  of application in the chemical industry. Together with the freely selectable operating medium of the liquid ring, the FGP allows volume flows of up to 700 m3/h.  In compressor mode gas pressures of up to p2 max = 2.5 barg are easily created.  In vacuum mode for aggressive media the pump produces suction pressures of  p1 = 100 mbara up to p1 = 25 mbara with an additional gas ejector. And this all  takes place at gas temperatures of up to 120 °C. The highly corrosion-resistant technical ceramic is perfectly suitable for all media containing chlorine and hydrogen chloride.
