• ACB 332

Note: identification by code and model is the most reliable method. In case of doubts about the pump version or the installed configuration, it is advisable to check the unit documentation or the code on the nameplate.

Typical applications (nautical and onboard plant engineering)

Replacing the seal may be part of targeted interventions to restore the correct functionality of the unit, especially when working on pumps used in circuits where service continuity and system reliability are important.

When replacement can be useful

• During a scheduled pump overhaul.
• In case of wear of the existing component.
• After disassembling the pump unit, when it is preferred to restore the sealing components.
• As a stock spare to reduce plant downtime.

Why rely on the code/model reference

• More precise ordering: the product code is a unique reference in spare parts management.
• Simpler maintenance management: useful for recording interventions and planning replacements.
• Consistency with documentation: facilitates comparison with manuals, exploded views, and spare parts lists.

Usage and operational notes

The mechanical seal is a component that requires attention during installation. For a correct result, it is good practice to operate following the procedures provided for the specific pump and using appropriate tools. If the intervention is carried out in a nautical environment, it is also advisable to consider the accessibility conditions of the technical compartment and the need to correctly restore the assembly of the unit.

Practical advice (general)

• Preliminary check: check pump model (ACB 331/1, ACB 331/2, ACB 332) and code correspondence RACB3301.
• Check related components: during disassembly it may be useful to also inspect adjacent parts (seats, mating surfaces) to assess any signs of wear.
• Cleaning and care during assembly: work on clean surfaces and handle the component carefully to avoid accidental damage.
• Documentation: refer to the pump manufacturer's instructions for assembly sequences and final checks.

Note on compatibility

The compatibilities listed on the page derive from the available content and refer to the pumps ACB 331/1, ACB 331/2 e ACB 332. If your installation has a variant or a different configuration, the safest way to confirm the choice is to compare the spare part code RACB3301 with the technical documentation or with the removed spare part.
