Applications

Application verified on Mase generator sets

The replacement 92911 It is suitable for the following Mase generator sets:

• VS 15.5 Low
• VS 17.5 Low

This compatibility is reported in the spare parts documentation. In case of doubts (for example, assembly variants or updates over time), it is advisable to check the spare part code required by your generator set before ordering.

Scope of use

The kit is intended for sea water pump, central component of the cooling circuit in generator sets. It is a typical spare part for scheduled maintenance and for interventions when signs of wear or the need to restore sealing are detected.

Operational advantages

• Complete kit for the intervention: impeller + sealing elements (gaskets and O-rings) in a single supply.
• Consistency with Mase coding: identification through code 92911 helps reduce errors during spare parts procurement.
• Suitable for onboard maintenance: practical format for interventions on seawater cooling systems in nautical/plant engineering contexts.
• Sealing restoration: replacement of gaskets and O-ring supports the correct closing of the pump after opening for maintenance.

Usage and technical notes

Function of the impeller in the seawater pump

The impeller of the seawater pump has the task of:

• sucking seawater from the sea intake;
• feeding the cooling circuit of the generator set;
• contributing to the proper cooling of the engine and the heat exchanger.

During maintenance, the gaskets shape and the’O-ring allow restoring the pump's sealing, reducing the risk of leaks due to worn or deformed sealing elements.

Practical indications for replacement

• Code verification: before installation, check that the replacement part is the 92911 and that the impeller is Johnson J09-1027B.
• Seal management: during reassembly, use the gaskets shape and the’O-ring included in the kit to restore the correct seal.
• Final check: after the intervention, check for the absence of leaks at the pump body and the regularity of the seawater circuit.

For a correct execution of the intervention, follow the procedures provided by the manufacturer of the generator set and the pump.
