Peristaltic Pump 12V Dc Kamoer High Flow 500Ml/Minute Khm 3 Rotors Liquid Dosing Volts:DC 12V?Flow: 500ml/min, Norprene tube?4mm ID 7.2mm OD?Working temperature: 0~40??Relative humidity 80%?Rotor:3 rotors. This peristaltic pump adopts engineering plastic gear transmission, which is cost-effective. The rotor is fixed by a triangular synchronous disc, and the internal gear structure design can stably and effectively prevent the pump tube from slipping. This peristaltic pump is suitable for the transmission of viscous and non-viscous liquids with a large flow rate. This peristaltic pump's appearance is compact, the upper cover of the pump body is made of PC plastic, the pump body is made of PA, and the gear material is made of synthetic engineering plastic. This peristaltic pump is widely used in experimental analysis, filling classification, scientific research institutions to do experiments, and food processing industries.
