Description
Plan 02 is a non-circulating flush plan designed for applications where adequate vapor suppression can be ensured. It is a simple and effective sealing solution that does not involve continuous circulation of process fluid to the seal chamber.
Advantages:
- No Continuous Solids Introduction: Solids from the process fluid are not continuously introduced into the seal chamber, reducing wear and potential clogging.
- No External Hardware Required: This plan does not require additional external components, making it a cost-effective and low-maintenance option.
- Natural Venting: When used with a tapered bore seal chamber, natural venting occurs, helping to manage vapors and gases effectively.
General Applications:
- Ideal for use with large bore/tapered bore ANSI/ASME B73.1 or ISO 3069 Type “C” seal chambers.
- Suitable for hot process pumps equipped with a cooling jacket.
- For additional cooling in hot services, Plan 62 with steam quench can be used in conjunction with Plan 02 to enhance performance.
Key Considerations:
- Adequate vapor suppression is critical for the success of Plan 02.
- Best suited for applications where solids in the process fluid are minimal or can be managed effectively.
- Natural venting in tapered bore seal chambers helps prevent vapor buildup, ensuring reliable operation.
Plan 02 is a straightforward and efficient sealing solution for specific applications, particularly where vapor suppression is achievable and solids introduction into the seal chamber needs to be minimized. Its simplicity and lack of external hardware make it an attractive option for large bore and hot process pumps. For enhanced cooling, combining Plan 02 with Plan 62 (steam quench) can provide additional benefits in high-temperature services. Plan 02 is a non-circulating flush plan ideal for large bore/tapered bore seal chambers and hot process pumps. It prevents solids from entering the seal chamber, requires no external hardware, and ensures natural venting. Perfect for applications with adequate vapor suppression.
