Small Diaphragm Expansion Tank for Home Water

Our 2-25L mini stainless steel pressure tank is a compact and high-performance small-sized Stainless Pressure Vessel independently developed and produced by our factory, belonging to the standardized light-duty Pressure Vessel series. Different from bulky traditional water storage equipment, this mini expansion tank features ultra-small body size, wall-mounted installation design and lightweight structure, which perfectly solves the problems of water pressure fluctuation, pipeline water hammer and thermal expansion and contraction of water volume in household and small civil water systems. As a professional manufacturer of Stainless Steel Pressure Tanks and supporting Industrial Air Brake Tank series products, we adopt integrated one-piece welding process for the tank body, with smooth and seamless welding lines, no water leakage and no air leakage. The outer layer is coated with high-adhesion anti-rust and anti-corrosion paint, which is resistant to oxidation and outdoor moisture erosion. The built-in high-elastic rubber diaphragm bladder is pre-charged with standard nitrogen pressure, with stable pressure storage and pressure buffering performance. It can effectively balance the water pressure of the circulating pipeline, avoid frequent start and stop of small water pumps, greatly reduce equipment loss and energy consumption, and provide long-term stable pressure stabilization guarantee for household water supply, heating and micro-circulation water equipment. All products comply with national and international pressure vessel safety standards, with reliable quality and wide applicability in civil small-scale water system scenarios.
