Members of your maintenance team would be familiar with the argument: original equipment manufactured (OEM) parts VS replicated parts.
OEM or replicated parts? Which is best for your pump?
Pump manufacturers will always argue that their parts are more efficient, higher quality and have lower total cost during the life of the pump. Those that manufacture replicated parts say their spares perform just as well as the OEM parts and cost dramatically less. But who do you believe? How do you know which parts will perform better?
If you’re focused on price, the answer is obvious: replicated parts. However, when it comes to reliability, it’s important to weigh up OEM and replicated parts to ensure, down the track, you’re making smarter spares decisions.
Consider the following points before making your decision:
- Non-OEM parts will void the original manufacturer’s warranty. Consider using the brand’s parts until the warranty expires and then seek advice on replicated spares.
- Potential to not meet the OEM performance specs. Some parts of pumps are very difficult to replicate, particularly impellers, where the vanes can be very hard to accurately duplicate. Therefore, even small changes in designs can have a big impact on the efficiency and performance of the pump.
- Copies could be made from worn parts. Non-OEM parts are sometimes copied from worn OEM parts and refined. Therefore, fits / tolerances are inaccurate, making the pump fail from the start.
- Replicators are missing original drawings. Some replicators do not have original pump drawings on hand to create accurate parts. OEMs are obsessed with quality, and most meet ISO 9001 quality control standards. It’s hard for non-OEMs to also meet these standards as they would need the original drawings to do so.
- Exact materials may not be available or may not match. Material mechanical properties and metallurgies may not meet the OEM standards - this could lead to corrosive, premature wear or reduce the pressure ratings.
Not sure what you need for your pump? Or maybe you’re concerned about switching from OEM parts to replicated? It’s important that you are aware of the risks with replicated parts - but they’re not all bad. Many pump companies have a wide range of spare parts which can be safely and efficiently retrofitted into any pump type. With experience, knowledge and an understanding of how pumps work, non-OEM parts from a reputable supplier, can save you dramatic costs down the line.
One of the key aspects is the warranty. If switching to replicated will void your warranty, it’s best to wait out the period. With most guarantees or warranties, you’ll receive a set period of spares and repairs - and you may as well enjoy this.
