Package includes :1x Diaphragm Water Pump Specifications :Volts: 12V DC(PS: 220V AC(Need a Transformer to work)Amps: 6ARated power: 72WPressure: 0.90MPA(MAX 130PSI)Flow capacity: 6L/MIN(6.0 Liters per minute)Working medium: no oil, no strong corrosive, non-acid and alkali, without solid particles of liquid;Medium temperature: 0 в„ѓ -100 в„ѓInlet and outlet size: 20mmSize: 16.5 × 10 × 6.2cmType: Pressure Switch/Reflux Switch(optional)Weight : approx.600g Features:1.Diaphragm pump combines the advantages of self-priming pump and chemical pump. Installed in a dry, well-ventilated location; pumps can not work in water.2.Using a variety of imported corrosion-resistant materials, self-priming, thermal protection, smooth operation, long-time continuous idling, long-time continuous load operation.3.Totally sealed, high stable pressure.4.Rubber bracket can absorb vibration from the pump when working.5.When the water pressure is too high, pump will protect themselves and normal work, water pipes will not burst, it is safe and durable.6.Pressure protection: pressure switch power protection.7.The maximum flow of 6 L / min, flow rate can be adjusted from 0.1 to 6 liters / min depending on the needs.Maximum pressure 130PSI (9.0 kg) of pressure can be adjusted from 75PSI (5 KG) -130PSI (9.0 Kg) according to different needs.8.The work: intermittent service (continuous working at different working pressures at different times)9.The use of media: water or solvent PH value 5--8, oil. Service life: more than 500-1000 hours of continuous work.10.Pressure Switch Type Features: When the water turned off, it will automatically cut off power,the motor is stopped. After the water turned on, will automatically power on, motor running.11. The shell is made of ABS plastic.
