Stainless Steel Buffer Tank

• Helps stabilize system pressure, absorb water hammer, and provide temporary storage and metering
• Optional jacket or insulation layer for temperature control
• Used in pharmaceutical, biopharmaceutical, food and dairy, fine chemical, HVAC, and constant-pressure water supply systems
• Food-grade and pharmaceutical-grade options available, with CIP and SIP configurations where required
• Customized according to working pressure, operating temperature, tank volume, and connection positions

A Stainless Steel Buffer Tank helps reduce pressure fluctuations caused by pump start-up and shutdown or sudden valve closure. Depending on its design, it may use a compressed-air chamber, an internal bladder, or another pressure-buffering arrangement to absorb pressure surges caused by water hammer. This helps maintain more stable flow and pressure while reducing stress on downstream pipes and equipment.
As an intermediate vessel, the tank can also provide temporary storage, metering, and blending. Jacketed or insulated models are available for processes requiring heating, cooling, or temperature maintenance. Where the design permits, additional configurations can support sterilization and other process requirements.
For vacuum systems, a suitably designed buffer tank can help stabilize vacuum conditions and separate gas from liquid. This may reduce frequent pump cycling and help improve operating efficiency, depending on the system layout and operating conditions.
Typical applications include the storage of raw materials, intermediates, and culture media in pharmaceutical and biopharmaceutical facilities, as well as hygienic liquid handling in food and dairy plants. Fine chemical production, coating resin processing, HVAC systems, and constant-pressure water supply installations also use buffer tanks for pressure control or intermediate storage.

The company has experience supplying buffer storage equipment for pharmaceutical and food processing facilities. Each Stainless Steel Buffer Tank is configured according to the intended process and operating conditions.
Before production, the working pressure, operating temperature, tank volume, connection positions, and jacket or insulation requirements are confirmed. Stainless steel plates are inspected before cutting and rolling. The tank shell is then welded and polished, followed by assembly, pressure testing, and other required inspections.

Please provide the working pressure, operating temperature, required volume, jacket or insulation requirements, and connection positions so the appropriate buffer tank configuration can be confirmed. Drawings or prototypes are welcome for customized production.
