Features:1 pump combines the advantages of self-priming pump and chemical pump Installed in a dry, well-ventilated location; pumps cannot work in water a variety of imported corrosion-resistant materials, self-priming, thermal protection, soft operation, long-time continuous idling, long-time continuous load operation sealed, excessive secure stress bracket can take in vibration from the pump when working the water stress is just too high, pump will protect themselves and regular work, water pipes won't burst, it is secure and durable 6 work: intermittent provider (continuous working at diverse operating pressures at diverse times)7 use of media: water or solvent PH cost 5--8, oil Service life: greater than 500-1000 hours of constant work Switch Type Features: When the water turned off, it'll mechanically bring to an end power,the motor is stopped After the water grew to become on, will routinely energy on, motor running most pressure has been set on the factory, and the maximum strain cannot be adjusted during use :Volts : 12V DCAmps : 5A Rateapower:60WPressure : 0(MAX 120PSI)Thelargestflow:5L/MINWorking medium: no oil, no strong corrosive, non-acid and alkali, with out solid particles of liquid;Medium temperature: zero ℃ -100 ℃Inlet and outlet size: 10mmSize: 16 × 10 × 6
