PRISMA is a diaphragm metering pump with a stepper motor. The microprocessor-controlled stepper motor ensures precision and uniformity of the metering process. The microprocessor controls the position and speed of the diaphragm throughout the entire delivery/suction cycle. The slow-running mode allows the suction speed to be reduced for optimal filling of viscous liquids. PRISMA metering pumps with a stepper motor ensure the most reliable metering process thanks to an incredible adjustment ratio of 1:4800, which allows for an extremely precise and uniform distribution of the product to be dosed, according to the needs of the application. Features: - Horizontal mounting, with display. - Diaphragm metering pump with a stepper motor. - Adjustment ratio of 1:4800. - Slow-running mode for viscous liquids. - The pump operating status is indicated by a multi-color display: pump running (green); standby mode (white); warning status (yellow); alarm status (red). - Power supply: 90 – 240 V, 50/60 Hz. - Manual pump head ventilation (PVDF and PP). - Double ball check valve. Accessories for basic model: - PVDF injection valve (0.3 bar). - PVDF level sensor. - PVDF filter. - PVDF supply hose (2 m). - Flexible PVC suction hose (2 m). - 4x6 PVC degassing hose (2 m).
