Key Findings

  • 01Two of the three evaluated pumps showed a significant decline in availability over the seven-year period.
  • 02One pump ultimately failed due to availability issues.
  • 03The primary cause for decreased availability was the discontinuation of OEM parts and the subsequent use of locally made substitutes.
  • 04OEM support and genuine spare parts are crucial for optimizing pump availability, reliability, and operational lifespan.

Application

Design takeaway

Factor in the long-term availability and support of critical components into the design and selection process to ensure sustained operational performance.

How to apply

When selecting components for critical systems, investigate the manufacturer's commitment to long-term parts production and support. Consider the availability and quality of aftermarket alternatives.

Project actions

  • 01When choosing materials or components for your design, research their availability and the manufacturer's support over time.
  • 02Consider how easy it will be to find replacement parts for your design in the future.

Method & Evidence

AimTo evaluate the impact of OEM part obsolescence on the availability trends of centrifugal pumps in an industrial setting.
MethodQuantitative analysis of historical operational data.
ProcedureCollected annual run-hour data for three specific centrifugal pumps over a seven-year period. Calculated pump availability using derived equations. Analyzed trends and identified causes for availability decline, correlating them with the discontinuation of OEM parts and the use of substitute components.
ContextIndustrial fluid transfer systems, specifically crude oil delivery operations.

Variables

IVDiscontinuation of OEM parts and use of substitute components.
DVCentrifugal pump availability (measured by run-hours and failure rates).
CVPump model, operational environment, maintenance practices (though some of these may vary and contribute to findings).

Strengths & Limitations

Strengths

  • +Uses real-world operational data from an industrial setting.
  • +Provides a clear link between a specific cause (OEM obsolescence) and effect (reduced availability).

Limitations

The availability of historical data can be a challenge. Replicating the exact conditions of the original study might be difficult.

Reliability & validity

The study's reliability is supported by the use of empirical data and derived equations. Validity is strong within its specific context, but generalizability may be limited.

Think critically

To what extent does the 'cost' of OEM parts influence the decision to switch to aftermarket alternatives, and how can designers mitigate the risks associated with this trade-off?

05

Design Principles

"Design for Longevity: Ensure that critical components have a clear and sustainable supply chain throughout the product's intended operational lifespan."

This highlights a critical risk in the long-term viability of industrial systems. Designers and engineers must consider the supply chain and lifecycle support of critical components, not just their initial performance, to ensure sustained operation and avoid costly downtime.

06

What This Means for Your Design

If the company that made a part stops selling it, and you have to use a different, maybe lower-quality part, your machine will probably break down more often.
