Micro peristalitic pump with a 500 motor for precious metal brushes, which driver the rollers (Three rollers) after deceleration, alternately squeezes the silicone tube to transport liquids. The characteristic of peristalic pumps is that they transport high pressure but low flow rate. Due to the high conveying pressure, peristalitic pumps are suitable for transporting viscous/non-viscous liquids such as ink or other viscous liquids. The upper cover plate of this batch of peristalitic pump is transparent, which looks quite good. The peristalitic pump has a three roller structure, with the lower half of the three rollers being gears. The (large) gears on the three rollers and the small gears on the motor shaft form a reduction ratio, which is a relatively new design. The characteristic of a peristalitic pump is its small flow rate but strong delivery pressure. When the voltage is DC 12V, its outlet pressure is even stronger. However, a peristalitic pump cannot be as quite as a diaphragm pump when pumping water, as it may experience shaking. Therefore, it is recommended to fix the pump before use. Suitable voltage: DC 6V-12V. Test data: Voltage: 6V Working current: 0.5A, Voltage: 12V Working current: 0.6A. Package Include: 1PC Pump
