Voltage:DC 12V 0.7A,Flow rate：200ml/min,3 rotors low pulse,weight：302g,BPT Tubing size：3.2mm ID x6.4mm OD. Bull head pump head, gear drive. Better fixed during operation and easy to maintain. The liquid does not touch the pump body, no pollution, low pulse,high precision. Easy to operate,it can be used by connecting the positive electrode and the negative electrode. You can change the direction of liquid flow by replacing the positive and negative electrodes. Two voltages, stable and controllable.Suitable for transporting viscous and non-viscous liquids. Applications：Experiment, environmental protection, aquarium field, printer coding, smart home, aviation operations,etc. 12V/24V peristaltic dosing pump, the newly designed bull head pump head shape makes the pump tube better fixed during operation, with strong performance, low noise, compact structure,200ml/min.
