Pressure Vessels
Sterlitech pressure vessels include main vessel and base, closure assemby, and dip tube assembly. Fittings, valves, gauges, and O-rings are available as optional accessories. Please contact us if you have questions or need more information, (877) 544-4420 or sales@sterlitech.com.
- Stainless Steel Type 304 or 316L
- 1 gallon to 10 gallon sizes (3.8 to 38 liters)
- Standard or Wide Mouth openings available for ease of cleaning.
- ASME certificate of analysis is available upon request.
- Electropolished finish provides a smooth, releasable, cleanable surface.
- Disassemble completely for thorough cleaning.
- Molded rubber base protects the vessel against rough handling (available with steel base for continuous operation at high temperatures).
- Use under positive or negative pressure.
- Optional vacuum closure available when working with negative pressure or when operating at low pressures. (<30 psi/2.1 bar) or with stiffer O-rings (FPM).
- Special orders available (coatings, additional sizes).
Applications
- Contain process fluids for filtration through pressure type membrane filter holders.
- Type 316/316L stainless complies with current good manufacturing practices and are recommended for low pH and high salt applications.
