Intended use

The spare part is described as mechanical seal for seawater. It is therefore designed for contexts where the pump operates with seawater, typical of many nautical installations. Using the correct spare part helps maintain the system in conditions consistent with the maintenance planned by the manufacturer.

Typical onboard applications

In the nautical field, mechanical seals are commonly replaced during maintenance interventions on pumps dedicated to onboard services. The TMD12Z refers to specific Gianneschi models and can be used in interventions such as:

• seal replacement following wear of the existing component;
• scheduled pump maintenance, when overhauling parts subject to wear;
• repair interventions following leaks or seepages detected during operation.

Proper spare parts management is particularly important in onboard systems, where reliability and continuity of service are practical aspects of daily maintenance.

Before purchase: what to check

• Spare part code: confirm that the requested code is TMD12Z.
• Pump model: verify that the pump is among the indicated models (JET B, JET4B, JET4RB, CB 160E, CB 160RE, CB 20E, CB 22E).
• Usage context: the spare part is indicated for seawater as per available description.

General intervention guidelines

Replacing a mechanical seal requires attention and good maintenance practices. In general:

• operate with the system stopped and safely isolated, disconnecting the pump from the circuit;
• thoroughly clean the seats and remove any residues of the previous component;
• avoid contamination and impacts on the seal surfaces during handling;
• check that there are no obvious anomalies on related components (for example seats or contact parts) before reassembly.

For procedures, disassembly and reassembly sequences, and final checks, it is advisable to refer to the pump documentation or the instructions of a qualified maintenance technician.

Useful notes for spare parts and assistance

To speed up order processing or support requests, it is helpful to provide:

• SKU: GIA000000178
• Supplier code: TMD12Z
• Pump model: one of those listed in compatibility

This information helps reduce ambiguity and identify the correct spare part more quickly.
