A. 【Multi-purpose Water Pump】DC 12V 70W 0.9Mpa 4 - 6L/min Self-priming Diaphragm Pump is a multifunctional equipment that allows for automatic water pumping and self-priming. It is suitable for use in caravans, boats, gardens and more. It shuts off when the pressure of the produced water is too high, which helps ensure safe use and prevent damage to the pump. This pump can be used for various purposes, such as water pumping, cooling welding guns, water drilling, cleaning, spraying, etc. B. 【Wide temperature range】 This self-priming water pump can be used for water temperatures from 0 °C to 1, water-based solvents with a pH of 5 to 8, as well as oil. Note that the pump can operate without water for a short time, but not more than 30 minutes. C. 【Easy to install】 The installation of this high-pressure water pump is simple. It is small and light, with a relatively high flow rate and pressure. There is no filter at the water inlet, so it is generally suitable for clean water. If there is dirt in the water to be pumped, it is recommended to install a filter. D. 【Material features】 This diaphragm water pump is made of materials that contribute to its performance. It has bearings that help ensure stable rotation and a relatively long service life. It has a flow rate of 6 l/min.
