Working Principle Use a water pump to pump water from a well or tap water pipe into a pressure tank, the air pressure in the pressure tank rises, and the pressure switch on the top of the tank controls the water pump to stop automatically. When you start using water, the air pressure in the tank decreases, and the pressure switch controls the water pump to start automatically to realize the fully automatic function.
Ultra high pressure resistance: the experimental pressure is 6 kg, the working pressure is within 3 kg, the vertical height can increase by 30 m. The top of the pressure tank is designed with three holes, the explosion-proof safety valve is installed separately, the pressure can be automatically discharged to prevent water pressure from rising. Automatic discharge to prevent water pressure vessels from forming a negative pressure when vacuumed.
Pressure vessel capacity: due to the pressure vessel above the compressed air, the actual storage capacity cannot be marked, this and the pressure setting has a direct relationship with the pressure set, the larger the pressure setting, the more water storage, 3-pressure water storage is about 50% to 70% of the total volume of the water, the water output is about 50% or so.
Food Grade Stainless Steel Material The pressure tank is made of food grade high performance stainless steel, which is waterproof, abrasion resistant, pressure resistant, odorless and resistant to high and low temperatures, and can be used in (-60℃ to 60℃) environments and can be used in direct contact with water, which meets the standard of human edible water and is very healthy.
About Installation:Please adjust self-priming pump or submersible pump according to the actual situation (Note: well water pump not included). It can be connected to water heater, washing machine, solar energy and other devices with automatic tower-free water supply pressure tank, which can be used for domestic life water, industrial/agriculture/livestock water, tap water pressure, garden irrigation.

Main highlights

Versatile applications: this pressure container is essential for various industries. Ideal for well water systems, industrial cleaning, increasing tap water pressure, horticultural irrigation and pure water filling - this tank meets a variety of needs, including campus water supply, agricultural and industrial applications, and building water distribution.
Robust and durable construction: made of food-safe stainless steel, our pressure tank is both rust resistant and exceptionally durable. The seamless design, made by fully automatic argon arc welding, ensures strong and visually appealing welds. It retains integrity in a temperature range of -60°C to 60°C, making it suitable for year-round use without risk of freezing or damage.
How it works: The pressure tank uses the compressibility of the air to balance energy storage and pressure regulation. When the water pump fills the tank, it compresses the air inside and stores energy. When water is needed, the release of compressed air effectively pushes out the water and ensures a uniform flow.
Generous water storage options: Our pressure tank is available in different sizes, including 100L, 160L, 200L, 250L, 300L to meet your diverse water storage needs. Please note that the effective water capacity is approx. 70% of the total volume of the tank and is designed for a maximum experimental pressure of 6 kg, with a working pressure below 3 kg.
Automated operation: simply connect your well or tap water pump to the pressure tank. The built-in pressure switch automatically controls the pump and ensures that it stops when the tank reaches the desired pressure. When water is pulled out of the tank, the air pressure drops, triggering the switch to refill the tank, creating a hassle-free, fully automatic experience.
