Please leave a message to us what plug you need . If not , we will add a plug according to standard of destination of country . This product has no filter at the water inlet, so it is suitable for clean water. If your water contains impurities (low impurities), please install a filter by yourself. Otherwise the pump will be blocked and will not work properly. Working method: Power on itwork, turn off the power it stop working!!! This is a diaphragm pump. The maximum continuous working time is 5 minutes. If it exceeds 5 minutes, it may cause damage to the internal motor of the pump. Four characteristics: 1. High pressure: generally reach 4-6Kg 2. Low power consumption: only 1.4-2.4A. 3. Long life: normal use, the motor life is more than 5 years. 4. Corrosion resistance: The large and small diaphragms are made of various imported materials. With oil resistance, heat resistance, acid resistance, alkali resistance, corrosion resistance, chemical resistance and other properties. Technical indicators: Voltage: 12V Current: around 4-5A Protection pressure: 0.8Mpa General pressure: 0.4-0.5Mpa Opening flow: 3-5L/min Dimensions: 160X100X60mm The suction stroke is 1-1.5 meters, lift 20 meters high. How to use: 1. The direction of the arrow on the pump is the water outlet. 2. The wires are not positive or negative. 3. The water pump can be placed in any direction. Precautions for use 1. Do not soak in water. 2. The pressure adjustment screw cannot be adjusted at will. Before leaving the factory, the pressure has been adjusted. If you adjust it at will, it is easy to increase the pressure of the backflow, and it is easy to hold back the water pipe. 3. A filter device must be installed at the water inlet to prevent impurities from entering. Otherwise, it is easy to block the water pump, resulting in a pressure drop and even no water.
