Specifications: 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 maximum flow of 6L/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 Gongjin) -130PSI (9.0 Kg) according to different needs. The work: intermittent service (continuous working at different working pressures at different times). The use of media: water or solvent PH value 5--8, oil. Service life: more than 500-1000 hours of continuous work. 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.
