Fault Diagnosis

The pump has failed due to being operated without an air filter. As a result, it has ingested dirty air over time, leading to the accumulation of contaminants within the internal components. This contamination has caused significant internal wear and damage.

Cause of Failure

Operation without an air filter, resulting in the intake of dirty air and subsequent internal damage.

Recommendation

To prevent future failures and ensure clean air intake, we strongly recommend the installation of an external POD filter.

Notes

The absence of adequate filtration has significantly compromised the integrity of this pump. Going forward, proper filtration must be in place to maintain pump performance and longevity.

Conclusion

The client has approved the repair and requested the installation of the external POD filter. The pump was successfully repaired, tested for performance, and prepared for dispatch.
