Kit features and details

The kit consists of specific spare parts for CB25/16B and includes mechanical and electrical components indicated in the list. Below is the list with the codes provided by the manufacturer.

Included components

• CUF31.5F – Capacitor MF 31.5 Double Faston (1 piece)
• RCB341 – O-Ring for CB 34 / CB 25/16 A-B 161x169x2mm (1 piece)
• RCB3421 – Impeller for CB 25/16B in bronze (1 piece)
• RCB346 – Key for CB34 / 25/16A / 25/16B 5x5x15 (1 piece)
• TMD18Z – Mechanical seal D.18 x 7 x 72Z7 Stainless Steel 316 Roten (1 piece)

What it practically includes

The set includes:

• Impeller, , central element for the correct hydraulic operation of the pump.
• O-ring, , useful for restoring the seal in the designated seats.
• Mechanical seal, , fundamental component for the separation between the hydraulic part and the motor part.
• Capacitor(s), , typical electrical component of single-phase versions.
• Key, , necessary for the mechanical coupling provided between shaft and driving element.

The presence of these elements makes the kit suitable for targeted maintenance interventions, when you want to replace multiple parts in a single operation, maintaining consistency between components and codes.

Typical applications

In a technical context (nautical and onboard plant engineering, but also light industrial installations or auxiliary systems), a spare parts kit like the KCB2516B02 is normally used for:

• Scheduled maintenance of the CB25/16B pump, with replacement of components subject to wear.
• Functional restoration in case of seal leakage or need for overhaul of the hydraulic part.
• Workshop or onboard interventions where it is useful to have spare parts already ready and identified.
• Stock management for maintenance personnel and operators who manage multiple units or multiple systems with pumps of the same series.

The kit refers to the configuration 220 V single-phase 50 Hz and the pump CB25/16B: for different variants it is advisable to follow the product code and the installed pump model.

Operational advantages

This spare parts kit is a practical solution for those who want to intervene in an orderly and consistent way on the pump, without having to source each component individually. In particular:

• Simple identification: the code KCB2516B02 helps reduce ambiguity when requesting spare parts.
• Consistency between components: the included spare parts are listed with dedicated codes, useful for internal traceability and maintenance.
• Reduction of procurement times: a single kit covers multiple typical overhaul needs.
• “Service-ready” approach”: useful for technicians and maintenance personnel who prefer to intervene by simultaneously replacing multiple related parts.

In the nautical field, where operational continuity and rapid intervention are often priorities, having a complete spare parts kit can simplify the planning of maintenance activities.

Usage and important notes

Check before installation

Before proceeding with the replacement of components, it is good practice to:

• check the exact pump code (CB25/16B) and the configuration 220 V single-phase 50 Hz;
• check that the spare parts codes match the list provided for the intervention;
• inspect seats, surfaces, and coupled components to identify any signs of wear that may affect the maintenance outcome.

General maintenance guidelines

Replacing the impeller, o-ring, and mechanical seal requires attention to correct assembly and cleaning of the seats. The capacitor is an electrical component: for replacement, it is advisable to operate safely and according to the maintenance procedures provided for single-phase equipment.

For interventions on onboard systems or in technical environments, it is recommended to carry out operations with qualified personnel and to perform a final check of the assembly before putting it back into service.

Codes and traceability

For assistance or reorder requests, use:

• Kit code: KCB2516B02
• SKU: GIA000000438

This information helps speed up product identification and reduce the risk of ordering incorrect spare parts.

Note

The description shows the kit composition and component codes as per the available list. If your pump has variants or different configurations, it is advisable to verify the exact kit code required before purchase.
