Mechanical seal – code: TMD18Z – Gianneschi Pumps and Blowers

Gianneschi mechanical seal – code TMD18Z

La mechanical seal with code TMD18Z is a spare part dedicated to specific pumps Gianneschi Pumps and Blowers, designed for maintenance and restoration of the pumping unit. In nautical and onboard plant applications, the correct shaft seal is a central element to keep the pump operational and reduce the risk of leaks during operation.

Features and identifying details

The component is identified by the supplier product code: TMD18Z and is associated with Gianneschi pumps belonging to the following series/models (as per available indications):

• CB Series
  • CB 25/16 (24V version)
• BMA Series
  • BMA 50/12

The mechanical seal is a functional spare part for the pump assembly and, during replacement, requires attention to surface cleaning, correct positioning, and checking the condition of adjacent components (seat, shaft, coupling parts). In case of doubts about the pump version or compatibility, it is advisable to compare the code TMD18Z with the exploded spare parts diagram or with the unit's identification label.

Useful codes and references

• Product code (supplier): TMD18Z
• Supplier: Gianneschi pumps and blowers S.R.L.
• Internal SKU: GIA000000186

Typical applications

Mechanical seals are commonly used on pumps installed in contexts where reliability and continuity of service are important, for example on onboard systems and auxiliary systems.

In practice, seal replacement may be part of activities such as:

• routine pump maintenance (inspection and restoration of wear components);
• repair following leaks or anomalies detected near the shaft;
• overhaul interventions during plant shutdown or refitting, when it is preferred to renew critical spare parts.

Operational advantages (from a maintenance perspective)

Using a spare part identified by supplier code allows working more orderly and reduces uncertainties during procurement. In a technical context, the availability of the reference TMD18Z helps to:

• simplifies the identification of the component during spare parts search;
• maintain consistency with the spare parts list and with the pump documentation;
• support maintenance with a component dedicated to the indicated series/models (CB and BMA as per list).

A mechanical seal in good condition contributes to the overall proper functioning of the pump, especially in applications where operational regularity and system care are central aspects of onboard management.

Use, notes, and recommendations

Replacing a mechanical seal is an operation that requires precision and good workshop practices. Below are some general guidelines (not a substitute for the manufacturer's instructions):

• Preliminary check: check that the pump corresponds to one of the indicated series/models and that the requested spare part is TMD18Z.
• Inspection of related components: assess the condition of the shaft and seats; any marks or wear may affect the outcome of the intervention.
• Cleaning and assembly: work on clean surfaces and handle the seal parts carefully to avoid damage during installation.
• Recommissioning: after reassembly, perform functional checks according to the procedures provided for the system.

Note: compatibility is indicated based on the information available on the datasheet (CB and BMA series with the listed models). If your pump has variants or different configurations, it is advisable to verify through Gianneschi technical documentation or through the spare part code shown on the exploded view.
