The pressure tank container needs to be equipped with a water pump to operate normally, this link does not include a water pump Product name: Automatic stainless steel pressure vessel Product material: food grade stainless steel Product capacity: 60L/100L/160L, the actual water storage capacity of the pressure tank is about 50%~70% of the volume Wide range of uses: pumping well water, industrial cleaning, tap water pressurization, garden watering, pure water filling Product accessories: non-return air supplement 2 in 1 valve, pressure controller, negative pressure explosion-proof integrated valve, water inlet union ball valve, pressure gauge, manual, 3* raw material belt, sewage outlet ball valve, sewage outlet elbow, water inlet Connector, outlet connector Product Size: 60L: 65cm high, 40cm diameter 100L: 95cm high, 40cm diameter 160L: 95cm high, 50cm diameter working principle 1. Pressure water supply belongs to air pressure water supply. The water pump presses the water into the pressure tank, the water volume increases, the air is compressed, and the air pressure is generated. 2. The air pressure in the pressure tank reaches the set value, the water pump stops working, and the water in the pressure tank can flow out at high speed 3. After the water in the pressure tank is reduced, the air pressure drops to the set value, and the water pump will start to inject water into the pressure tank again 4. In this way, fully automatic water circulation is achieved, increasing the water pressure to ensure sufficient pressure and stable water flow note: The delivery time is about 8-21 days, please be patient.
