OEM, Non-OEM, Upgraded & Engineered Pump Parts

Based on client needs around design, cost, delivery, and quality, Westpower provides the optimal solution, offering OEM, non-OEM, or upgraded parts to ensure the best fit for performance and reliability.

Non-OEM Pump Parts, Designed to Keep You Producing

Westpower understands the rigorous demands of industrial, engineered, and process pump applications. Pump reliability is critical to operational efficiency, from oil & gas and petrochemical processing to power generation and water treatment. While OEM parts are often the default choice, high-quality non-OEM pump parts offer a cost-effective and reliable alternative to meet or exceed OEM pump part specifications. Non-OEM parts are also essential for aging or legacy equipment no longer supported by OEMs, ensuring continued operation without costly system overhauls or replacements. Westpower enhances legacy pumps with fit-for-purpose, engineered non-OEM parts that optimize performance and often exceed original pump’s performance.

FAQs | Non-OEM pump replacement parts

Are non-OEM parts as reliable as OEM parts?

The reliability of non-OEM parts depends on several factors, including the manufacturer’s expertise and adherence to design specifications. While OEM parts are built to strict standards, ensuring consistent fit, performance, and reliability, non-OEM parts can vary. Some non-OEM parts may offer cost-effective alternatives or even improved performance, but they may come with risks related to material quality, tolerances, and long-term durability.

By working with an experienced manufacturer like Westpower, you can mitigate these risks, as we apply deep engineering knowledge to ensure that both OEM and non-OEM parts meet high reliability, performance, and quality standards. The key decision ultimately comes down to balancing quality, cost, and delivery while evaluating the long-term benefits for your pump system’s performance.

How do non-OEM parts help reduce costs?

Non-OEM parts can often reduce costs through lower initial prices, faster delivery, and tailored designs. While they are often more readily available, some custom non-OEM parts, engineered with enhanced materials for specific applications, may not always be cheaper. However, they can still provide long-term savings by improving performance and extending part lifespan, ultimately lowering your total cost of ownership.

Will non-OEM parts fit my existing pump?

Absolutely. Our non-OEM parts are designed for exact compatibility with a wide range of industrial, engineered, and process pumps. Our team of experts ensures that every component is precision-matched to your pump’s specifications, providing a reliable and efficient replacement solution.
