Pressurized Tank Mixers
ASM Group
Sealing Technology for Process Containment
A primary functional requirement of a pressurized tank mixer is the sealing arrangement where the rotating shaft enters the vessel. Available arrangements may include lip seals, packing or stuffing boxes, single mechanical seals and double or cartridge mechanical seals. The appropriate arrangement depends on vessel pressure or vacuum, temperature, shaft speed and runout, product compatibility, allowable leakage, emissions requirements and maintenance access. Split construction may be considered where access or service requirements make it beneficial. Seal materials and support systems are selected for the process conditions and the customer’s operating requirements.
Engineered Configurations for Closed Vessels
Pressurized tank mixers are configured to meet the mechanical requirements and fluid rheology of the application. Pedestal mounted arrangements are available and provide clearance for seal inspection and service. Depending on output torque, speed and fluid viscosity, the power transmission may use a direct drive or gear reduced configuration. Bearing assemblies are selected for a calculated L10 life based on the specified loads and duty cycle. The submerged assembly can be equipped with hydrofoils, pitched blade turbines, flat blade turbines or other impellers selected for the required circulation, shear and dispersion.

Our Pressurized Tank Mixers: ASM Group
Our ASM Group includes a range of heavy-duty, non-atmospheric agitators designed for sealed or pressurized mixing applications. These units share the same core design as the AHM Group but are specifically configured for systems requiring vacuum or pressure containment. Each mixer is built for demanding process environments, combining reliability, performance, and mechanical integrity.
Vessel Sealing
Seal selection for the ASM Group depends on the vessel pressure or vacuum, the temperature, the fluid, shaft speed and runout, the allowable leakage, and the access available for maintenance. Arrangements we commonly supply include:
- Lip seals for low-pressure service.
- Split mechanical seals or stuffing boxes for moderate pressure or vacuum.
- Single or double cartridge mechanical seals for higher pressure or full vacuum.
Seals come from established manufacturers, and we can work to a specified brand where the application allows. Materials are selected for compatibility with the service. ASM mixers are normally pedestal mounted, which leaves clearance for inspection and seal replacement.
