IMP2 rubber impeller for UP1-J – code: 16300100 – Marco

IMP2 rubber impeller for Marco UP1-J pumps (code 16300100)

The IMP2 rubber impeller is a original Marco replacement designed for pumps UP1-J. It is a fundamental consumable component for the proper functioning of the pump: the impeller, rotating inside the pump body, contributes to the movement of the fluid and, with use, may require replacement as part of normal maintenance.

This model is made of nitrile rubber (NBR) and is identified by the supplier product code 16300100 (denomination IMP2). It is a solution recommended for those who want to maintain the original pump configuration and restore functionality with a replacement consistent with the manufacturer's specifications.

Spare part features and details

The IMP2 impeller is defined by the manufacturer as an impeller in special nitrile rubber. The dimensions and construction details provided allow precise identification of the spare part and verification of its correspondence with the pump on which it must be installed.

Typical applications (nautical and onboard plant engineering)

The impeller is a frequently requested spare part for routine maintenance or functional restoration. The IMP2 is specific for use on Marco UP1-J pumps and can be used when:

• periodic scheduled maintenance more regular water flow;
• consumption wear impeller damage or efficiency loss related to the component;
• you want to keep on board a spare replacement element is useful for quick interventions;
• you proceed with a restoration after a plant shutdown or a period of inactivity.

Being an original spare part, it is recommended for those who prefer to keep the pump in the configuration compliant with the Marco supply.

Advantages of the original Marco spare part

Choosing an original impeller, identified by the correct code, helps reduce uncertainties during replacement and maintain consistency with the manufacturer's specifications.

• Dedicated spare part: designed for Marco pumps UP1-J (declared compatibility).
• Clear identification: code 16300100 and designation IMP2 for easier reordering.
• NBR material: nitrile rubber indicated by the manufacturer for this application.
• Defined geometry: specified dimensions and hole (Ø 40.5 x h 22; hole Ø 8.00) and 6 blades, useful for checks and comparison with the existing component.

Use, replacement and operational notes

Replacing the impeller is part of the typical maintenance activities for pumps. To operate in an orderly manner and reduce the risk of errors, it is advisable to follow the pump manual instructions and work safely.

Before starting

• Check that the pump is off and not powered.
• Ensure that the system is in suitable conditions for the intervention (for example, avoiding unwanted fluid leaks).
• Check that the replacement corresponds to what is required: IMP2, 16300100, hole Ø 8.00, dimensions Ø 40.5 x h 22, 6 blades.

During replacement

In general, the operation involves accessing the impeller seat and removing the worn component, followed by installing the new impeller. If the removed impeller shows obvious signs of deterioration, it is appropriate to also inspect the seat and contact parts to verify that there are no residues or anomalies that could compromise the assembly.

After installation

• Perform a visual inspection of the assembly before putting it back into service.
• Verify the correct operation of the pump according to the procedures provided by the manufacturer.

Practical advice

To reduce downtime, it can be useful to keep a spare impeller on board identified by the correct code. When reordering, always report 16300100 and compatibility UP1-J to avoid misunderstandings.
