What are the applications of stainless steel sanitary pumps?

Stainless steel composite underground water tanks are constructed using stainless steel–galvanized dual‑metal composite panels, formed into tank modules through stamping and deep drawing. The stainless steel composite layer ensures hygienic water quality, while the galvanized steel provides robust mechanical strength. With no welded joints in the entire panel that come into contact with water, this design maintains pristine water quality and prevents corrosion of the tank walls, making it an excellent material for prefabricated water tanks. Installation and maintenance require no welding—only bolted connections—offering simplicity, speed, and convenience.

Inlet pipe: The water tank’s inlet pipe is typically connected to the outer wall, though it may also be attached at the bottom or top. When the tank is filled by mains‑pressure water supplied through the distribution network, the inlet should be fitted with a hydraulic level‑control valve or a float valve as close as possible to the outlet. If the pipe diameter is 50 mm or greater, at least two such valves are generally required. Each control valve must be preceded by a service shut‑off valve. If the tank is supplied via a booster pump and equipped with an automatic level‑controlled pump‑start system, a pressure‑regulating valve should not be installed. The tank is constructed from food‑grade SUS304 stainless steel, offering exceptional corrosion resistance and permanent rust‑free performance. Its smooth surface reflects sunlight effectively, minimizing heat absorption, while preventing the growth of algae and moss inside, thus maintaining clean water quality. Cleaning is also exceptionally easy in later stages.

Stainless steel domestic water tanks are typically constructed from SUS304 stainless steel, which boasts stable physicochemical properties and does not contaminate the water, thereby ensuring clean and hygienic water quality. Indoor fire‑fighting water tanks (traditional fire‑water reservoirs) are generally installed on the ground floor, with a capacity larger than that of rooftop stainless steel fire‑fighting tanks; their volume is usually designed to range from 60 to 2,000 cubic meters.

This is what people commonly refer to. Such steel plates have a high nickel content and exhibit excellent corrosion resistance. Water tanks made from this type of steel typically last for more than twenty years and meet the hygienic standards for potable water. However, due to market competition and consumers’ inability to distinguish between different grades of stainless steel, many small, independent manufacturers use non‑food‑grade steel—such as decorative 201‑grade stainless steel—to produce water tanks, reducing costs by over 50%. Yet these tanks last only a few years; in poorer water conditions, they may corrode and leak within just a few weeks. 2. Pay attention to the thickness of the steel plate. Stainless steel is measured in millimeters; standard household water tanks (under 2 m³) are usually fabricated from 0.4–0.5 mm‑thick sheets, with 1.0 mm or thicker rarely employed. Some manufacturers, seeking to deceive consumers and maximize profits, …

Stainless‑steel domestic water tanks are ideal for large hotels and restaurants, government offices, apartment complexes, research and educational facilities, and sectors such as food processing, sanitation, and electronics—environments with stringent water‑quality requirements.

The tank is manufactured by stamping standard water‑tank modules from a composite of 304 stainless steel and galvanized steel using a specialized process, then assembling them with bolts. This ensures excellent hygienic conditions. The parts that come into contact with water are formed by deep drawing from high‑quality stainless‑steel sheets.

All sanitary indicators of the water tank comply with national industry standards and have passed hygiene inspection and quarantine. It does not rust or leak, nor does it develop algae. The stainless steel tank ensures that the water source remains free from secondary contamination and is easy to clean.

Water tanks are generally categorized into three sizes. The upper and lower components of the tank are extensively used, with clearly defined lines. The price of a water tank depends on the supplier’s quality, so high‑end models often feature large casings from brands like Patek Philippe. Low‑carbon steel water tanks are characterized by high strength, resistance to bending and fracture, impact resistance, corrosion resistance, heavy‑load capacity, compact size, and robust construction. Stainless steel water tanks, classified by heat resistance, include straight‑flow, sloped‑roof, balcony, horizontal‑leisure, bed‑type, corridor‑type, and bathroom‑type designs.

Stainless steel domestic water tanks are suitable for large hotels and restaurants, government offices, apartment buildings, research and educational facilities, as well as food-processing plants, healthcare institutions, and the electronics industry—places where water quality is of paramount importance. They offer more thorough cleaning, produce no noticeable odors, and do not corrode the tank itself. By contrast, conventional cleaning agents may fail to fully remove scale and can even cause corrosion, leading to unpleasant odors; moreover, they often fall short of effectively eliminating stubborn mineral deposits. In contrast, specialized tank descalers significantly extend the service life of the tank. Compared with standard descaling methods, they deliver superior results.

Stainless steel domestic water tanks are easy and quick to install: standard stamped panels measuring 1,000 × 1,010 × 5,500 × 500 mm can be freely assembled on site using argon arc welding, eliminating the need for lifting equipment.
