ZEFIROA WORKING PRINCIPLEThe LARIUS ZEFIRO unit is defined “electric piston pump”.An electric piston pump is used for high pressure painting withoutair (from this process derives the term ”airless”).The pump is controlled by an electric motor coupled with areduction gear.A cam shaft and a connecting rod allow to obtain the reciprocatingmotion necessary to the working of the “pumping group” piston.The piston movement produces a “vacuum”.The product is sucked, pushed towards the pump outlet and thensent to the gun through the flexible hose.An electronic device located next to the reduction box, is usedto regulate and control the pressure of the material leaving thepump. When the pump reaches the set value, the motor stops andstarts again when the value decreases.A safety valve avoiding overpressure, guarantees the total reliabilityof the equipment.EnglishFields of applicationApplications materialsIndoorOutdoorIndustrial buildingsIndustrial constructionsRedevelopingRoofingLacquerWaterborneAcrylicEnamelsFixativePaintsEmulsionsFillersPrimer3
