Micro Diaphragm Pump AC Electric High Pressure Boost Self Suction for Cleaning 15L/Min 4.0GPMEU Plug(220V) Item Type: Micro Diaphragm Pump Product Material: Engineering plastic Volume of Solid Impurities: ≤0.1 Particles: Not larger than 0.2mm Environment Temperature: ≤50℃ Medium Temperature: 0-65℃ PH Range: 5.0-10 Flow Rate: 15.0L/min Head: Approx. 38meter / 124.7ft Suction Head: Approx. 3.0meter / 9.8ft Gallon: 4.0GPM Use Scenarios: Car wash, filling machine, garden agricultural spraying, agricultural spray, water heater, household water booster, RV, yacht, shower booster, green spraying mist Note: 1. When the water pump is working, it is necessary to ensure a smooth drainage of the water pump to avoid holding the pump and causing damage to the pressure switch 2. If you hear the abnormal sound of the switch ticking during operation, please turn off the pump immediately and increase the pressure appropriately 3. The motor has a slight waterproof function. There is no need to worry too much about splashing a little water (you can wipe it dry), but it is strictly forbidden to soak the pump motor in water. If the pump is placed in the open air, it should be covered to protect it to prevent water from splashing into the motor. Cause power failure, leakage or motor damage 4. The water inlet must be installed with a filter device, and liquids with impurities cannot be sucked in, otherwise it will easily block the water pump, which will cause the pressure to drop and the flow rate will decrease, or even the water cannot be pumped. 5. It is strictly forbidden e this machine without the filter connected, and the density of the filter is preferably above 80 grit (impurities will cause damage to the pump) 6. The pump works intermittently, and it must not work 24 hours a day 7. Please disconnect the connection between the motor pump and the power supply when it is not used for a long time or when it is temporarily suspended. 8. The water pump has a pressure switch adjustment function. The pressure can be adjusted appropriately according to its actual needs, but it cannot be adjusted too small or too large. A switch that is too small will easily start and stop frequently and cause burns. If a switch is too large, it may not work. To function, causing the pump to not shut down normally 9. Please confirm the power supply before use, the power supply parameters must be consistent with the input parameters of the motor pump 10. In order to avoid water leakage to the rotor when the product fails, the correct installation method is that the pump head is down or placed flat
