Features: Pressure switch type: When the outlet is completely blocked (without water leakage), the power will be automatically cut off, the motor will stop running, and the water outlet will be opened and then run again. The matching nozzle should not be too small, which may damage the pressure switch inside the pump, but the nozzle should not be too large, and the working pressure will be very small. Equipped with self priming function, it can also be used at low water levels. 12V safe low-voltage, no danger of electric shock. Adopting a plastic shock-absorber base can effectively reduce noise. Easy to use. Suitable for industrial equipment, pharmaceutical-equipment, chemical-equipment, agriculture (lawn and garden), tourist vehicles, ship beverages, vehicle cleaning, carpet cleaning, floor cleaning, water purification, and water treatments equipment.
