Peristaltic Pump, Mini Tiny 8mm Precision Gear Stepper Motor Pump Dosing Full Metal Gearbox Self-Priming Liquid Flow Control

Brand new original 8mm stepper reduction motor precision peristaltic pump, precision all metal mini peristaltic pump, all metal gear reduction pump head group, peristaltic pump supports changing the direction of water flow in both directions, copper roller peristaltic pump head, with high requirements for workmanship. The pump tube adopts 2.5mm silicone tube, and the motor is an 8mm two-phase four wire stepper motor with a phase resistance of 22 ohms. The peristaltic pump weighs 5.2 grams. The nominal voltage of the motor is DC5V and the rated current is 150mA. The maximum flow rate tested using our store's stepper motor drive board is 0.5mL/minute. The stepper motor can achieve high-precision quantitative output, but specific research is needed. Our store's simple driver can support a maximum voltage of DC 3V-5V and can be powered by a single DC 3.7V lithium battery. Low voltage will affect the maximum speed of the motor, and the flow rate will be smaller under low voltage power supply. Stepper drivers need to be purchased separately.
