Description: 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. Using a variety of imported corrosion-resistant materials, self-priming, thermal protection, smooth operation, long-time continuous idling, long-time continuous load operation. Totally sealed, high stable pressure.Rubber bracket can absorb vibration from the pump when working.When the water pressure is too high, pump will protect themselves and normal work, water pipes will not burst, it is safe and durable. Pressure protection: pressure switch power protection.The work: intermittent service (continuous working at different working pressures at different times) The maximum flow of 5-6 L / min, Maximum pressure 7.0 kg, both of them can't be adjusted. 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. The shell is made of ABS plastic.The maximum pressure has been set at the factory, and the maximum pressure cannot be adjusted during use. Specification: Volts : 12V DC(PS: 220V AC(Need a Transformer to work Amps : 6A Rated power:72W Pressure : 7kg 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: 0-100 C Inlet and outlet size: 10mm Type: Screw thread/straight Size Chart: 16.5×10×6.2cm/6.50×3.94×2.44inch Package Includes: 1X Water High Pressure Diaphragm Water Pum Note: 1.
