Feature: Maximum pressure 130PSI (9.0 kg) of pressure can be adjusted from 75PSI (5 Gongjin) -130PSI (9.0 Kg) according to different needs. When the water pressure is too high, pump will protect themselves and normal work, water pipes will not burst. Diaphragm pump combines the advantages of self-priming pump and chemical pump. Using a variety of imported corrosion-resistant materials, self-priming, thermal protection, smooth operation, long-time continuous idling, long-time continuous load operation. bracket can absorb vibration from the pump when working. Specification: Type: straight Amps: 6A Rateapower: 70W Pressure: 0.90MPA (MAX 130PSI) Thelargestflow: 6L/MIN Medium temperature: 0℃ -100℃ Working medium: no oil, no strong corrosive, non-acid and alkali, without solid particles of liquid The use of media: water or solvent PH value 5--8, oil Pressure protection: pressure switch power protection 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 work: intermittent service (continuous working at different working pressures at different times) Service life: more than 500-1000 hours of continuous work note: Batches of different labels are random, Cannot be chosen the specific random Material: plastic colour: black Package Contents: 2 x Straight right discharge pump
