Stainless Steel Buffer Tank for RO and Pressure Stabilization Systems
Stainless Steel Buffer Tank for RO and Pressure Stabilization Systems
The STARK stainless steel buffer tank is a robust pressure-stabilizing solution engineered for industrial and commercial fluid systems. Whether used in reverse osmosis (RO) systems, secondary water supply networks, or chemical dosing applications, this tank helps balance pressure fluctuations, minimize pump cycling, and protect downstream components.
Built from food-grade SUS304 or SUS316 stainless steel, it ensures long-lasting performance even in corrosive or high-demand environments.
Detailed Description
The STARK Stainless Steel Buffer Tank is engineered to deliver unmatched pressure stabilization and system efficiency across a wide range of industrial and commercial applications. Acting as a crucial intermediary between water sources and end-use equipment, the tank efficiently absorbs pressure spikes and minimizes hydraulic shocks, prolonging the service life of pumps, pipelines, and sensitive instrumentation.
Constructed from high-grade SUS304 or SUS316 stainless steel, the tank offers excellent corrosion resistance, making it suitable for aggressive water types, including brackish, demineralized, and high-purity water. The tank’s internal surface is mechanically or electropolished to ensure hygiene compliance, reducing the risk of biofilm formation and enabling applications in food, pharmaceutical, and ultrapure water systems.
With a customizable volume capacity ranging from 100L to 20,000L, and pressure ratings of up to 10 bar (customizable to higher levels upon request), the tank can be tailored to fit both small-scale utility needs and large-scale industrial installations. The cylindrical body with elliptical or torispherical heads enhances structural integrity while minimizing dead zones inside the tank.
The standard design includes top-mounted air vents or gas release ports, as well as side or bottom flanged nozzles for inlet/outlet control. Optional accessories such as pressure gauges, manholes, CIP (Clean-in-Place) spray balls, level indicators, insulation jackets, and frame mounting kits are available to meet project-specific needs.
All STARK buffer tanks undergo rigorous hydrostatic testing before dispatch, and come with export-ready packaging and full documentation for global shipping. We support complete customization for OEM/ODM clients, and provide integration support for RO systems, cooling towers, chemical dosing setups, and HVAC stabilization loops.
