12V DC 4-6L/Min 0.90MPA 130PSI 70W 6A High Pressure Diaphragm Water/fluid Pump BX4, R28

DescriptionWhen a standard submersible aquarium pump simply doesn’t have the power to push water through long hoses or misting nozzles, you need to upgrade to a diaphragm pump. The 12V 130PSI Diaphragm Water Pump is a heavy-duty, self-priming workhorse designed specifically for high-pressure applications.Whether you are designing a smart-agriculture pesticide sprayer for a final-year engineering project, or setting up a high-pressure cooling mist system for a summer training facility, this pump delivers reliable, continuous flow.The Automatic Pressure SwitchOne of the best features of this pump is the black sensor box mounted on the top head: the automatic pressure switch. This mechanical sensor detects back-pressure in the water line. If you attach a spray gun or an automated solenoid valve to the output hose and close it, the pump immediately senses the pressure spike and cuts power to the motor. The moment you open the valve again, the pressure drops, and the pump instantly turns back on. This saves power and completely prevents the motor from overheating or bursting your pipes.Interfacing with Microcontrollers (IoT Integration)While this pump operates on a safe 12V DC, it is a high-power device that draws up to 6 Amps (70 Watts). Crucial Note: You absolutely cannot connect this directly to an Arduino, ESP32, or a standard breadboard. To control this pump programmatically (for example, triggering it based on soil moisture sensor readings), you must use a heavy-duty relay module (rated for at least 10A DC) or a high-power N-channel MOSFET (like the IRF520 or IRLZ44N).Vibration-Damping MountsHigh-pressure pumping generates mechanical vibration. This unit features thick rubber mounting feet that absorb the motor’s kinetic energy, significantly reducing operating noise when bolted to a rigid frame, enclosure, or water tank.Key Features:Self-Priming: Capable of pulling water up from a tank even if the pump itself is mounted above the water line.Smart Cutoff: Internal pressure switch automatically cycles the pump based on outlet flow.High Pressure: 0.90 MPa translates to roughly 130 PSI—enough force to create fine mist or a strong jet stream.Durable Build: Resistant to mild chemicals, making it suitable for agricultural fertilizers and non-corrosive weed killers.Technical Specifications:Rated Voltage: 12V DCWorking Voltage Range: 9V to 14.4V DCMaximum Current Draw: 6APower Rating: 70WMaximum Flow Rate: 4.0 – 6.0 L/MinCutoff Pressure: 0.90 MPa (130 PSI)Inlet/Outlet Interface: Threaded ports (includes standard hose clamp adapters)Ideal Applications:Automated IoT agricultural irrigation and hydroponicsDIY car washing kits and high-pressure sprayersGreenhouse misting and temperature control systemsRV, camper, and marine boat pressurized water systemsFluid transfer for electronics summer bootcamp hardware labsPrecautionsThis product is powered by DC, and it is strictly forbidden to directly connect to 220V AC.Please install a filter net of 80 mesh or more at the water inlet of the pump when in use .The diameter of the water spray hole must meet the specified value, otherwise the motor will be damaged. When the pump body of the pressure switch pump vibrates, the diameter of the nozzle hole should be increased , the flow rate should be increased or the pressure output value should be reduced.The working environment temperature of the pump: 0～60 ℃, the pump should not work in an environment with too much humidityPackage includes: 1×12V DC 4-6L/Min 0.90MPA 70W 6A High Pressure Diaphragm Water Pump
