Specification:Brand new original Japanese NIDEC SANKYO gear pump, two-way self-priming pump. It can be said that Nidec products are basically of good quality and details. They use Japanese Mabuchi motors and Japanese NOK water pumps. The materials are basically ABS and PPE materials, and each sub-component has a component identification.The nominal rating of the pump is DC12V, and the actual 5V can work. Even if the overpressure reaches 18V, the working state is still very good. The higher the voltage, the greater the flow pressure.If the nozzle is not added with a pipe to reduce the diameter, it will not feel the pressure. It is similar to the 19bar imported electromagnetic pump from Italy sold by the shop owner, which can spray very far.The size of the caliber has its own advantages and disadvantages. The larger the caliber, the smaller the pumping load and the smaller the operating current. Reducing the caliber is equivalent to increasing the load, and the working current will also increase. The nozzle is only the size of a needle, and the starting current is relatively large for this reason. In terms of the specific voltage used, the buyer needs to judge according to their own and actual situation.The characteristics of the gear pump are that the flow rate is generally not large.If you need to change the direction of water flow, you can switch the positive and negative poles of the wiring.Test the parameters under several typical voltage conditions for reference:Voltage: 5V Pump Water Current: 40maVoltage: 12V Pump Water Current: 80maPump weight is about 103 grams.=============================================================================Package List:Pump x 1pcs
