18V 555 motor high pressure jet pump, with self-priming function, maximum pressure 8bar, originally estimated to be used in high pressure spray or high-end water gun stora high pressure pump, 8bar pressure flow of about 150mL/ minute, open without pressure maximum flow can be 1600mL/ minute, and ordinary diaphragm pump similar. The two types of interface specifications, parameters and performance are the same, one type of import and export is arrand at right angles, the other type of import and export is horizontal, choose to buy according to demand. The nominal of the pump is 18V, the no-load current of the test pump pump water is 0.15A under 12V, and the maximum flow rate without pressure can reach 900mL/ min. The no-load current of the test pump pump water under 18V is 0.2A, and the maximum flow rate without pressure can reach 1600mL/ min. The measured overpressure is 24V, which is not a big problem. The specific use needs to be tested by yourself. The pump weight is about 275 grams.
