Let us help you find the right product from this series
Product features
- Recirculation from pump discharge to the seal through a flow-control orifice → Uses the process fluid to support seal-chamber conditions for clean, non-polymerizing service
- Minimum stated orifice size is 3.2 mm (1/8 in) → Provides a verified lower limit to check during Plan 11 engineering
- Series-specific selection against equipment data → Helps avoid specifying a seal that does not match shaft, housing or process conditions
- Verified material and operating-data check → Keeps compatibility decisions tied to documented AESSEAL information rather than assumptions
- AxFlow application support → Gives engineers a contact point for product selection, availability and service or spare-parts planning
- Exact model identification → Keeps maintenance and ordering tied to the installed configuration rather than a similar-looking variant
- Documented operating-limit review → Helps engineering teams separate verified design data from assumptions before approval
AESSEAL API Plan 11 is specified for mechanical seal systems where the selected API piping arrangement is used to manage seal-chamber or barrier-fluid conditions. It is intended for engineers and maintenance teams selecting a sealing solution around the actual equipment and process duty, where leakage control, service access and unplanned downtime need to be considered together. This API piping plan defines how fluid is routed around the mechanical seal to control seal-chamber or barrier-fluid conditions. It is a system arrangement rather than a stand-alone seal, so flow, pressure, temperature and process-fluid behaviour must be checked during engineering. Verified series-specific points include Recirculation from pump discharge to the seal through a flow-control orifice; Minimum stated orifice size is 3.2 mm (1/8 in). For model selection, verify shaft and housing dimensions, pressure, temperature, speed, process medium, solids content where relevant, material compatibility and the required support-system arrangement. Only values explicitly stated for the selected AESSEAL configuration should be used as design limits. Before replacement or retrofit, identify the installed seal or support-system code and record the mating equipment data rather than assuming family-wide interchangeability. This gives maintenance and procurement teams a traceable basis for comparing the selected AESSEAL variant with the installed configuration and planning the intervention. Correct selection and a serviceable arrangement can reduce avoidable installation work and help maintenance teams plan spares and interventions more predictably. AxFlow can support product selection, application review and service/spare-parts planning; contact AxFlow to confirm the exact configuration and availability.
