Rubber impeller IMP1 for UP1 – code: 16300000 – Marco

IMP1 rubber impeller for Marco UP1 pumps

The IMP1 rubber impeller is a spare part dedicated to Marco UP1 series pumps, designed for maintenance and restoration of system operation. This component is made of nitrile rubber and is identified by the Marco code 16300000 (IMP1), useful for quick identification during reordering or replacement.

In nautical and onboard plant engineering, the impeller is a wear-prone component: periodic replacement with a correct and pump model-compliant spare helps maintain system functionality. This IMP1 version is suitable for specific Marco pumps and includes essential measurements and features for a safe choice.

• Identifiable spare part via Marco code IMP1 – 16300000, useful for quick reorders.
• Material in nitrile rubber suitable for use as an impeller in pumping applications provided by the UP1 series.
• Defined geometry (hole, diameter, and number of blades) to match the indicated compatible pumps.
• Practical solution for maintenance and restoration interventions on onboard systems.

Usage and installation notes

Replacing an impeller is a typical maintenance operation. To work in an orderly manner and reduce the risk of errors, it is useful to follow some general good practices:

• Preliminary check: check that the pump model is among those indicated (UP1, UP1-M, UP1/AC) and that the spare part corresponds to the code 16300000.
• Dimensional check: compare hole and measurements (ø 8.00 mm; 22 x ø 51.50 mm) with the removed impeller, especially if the system has undergone modifications over time.
• Housing inspection: during replacement, check the condition of the seat and the possible presence of residues or fragments of the old impeller.
• Careful reassembly: ensure that the impeller is correctly positioned and that the pump components are uniformly closed.

Note: for specific procedures, refer to the pump manufacturer's instructions and the system's technical documentation. In case of doubts about compatibility, it is preferable to verify the spare part code and pump model before purchase.
