| Why use a 3500 RPM pump instead
of a 1750 RPM pump? It’s simple – speed saves. A 3500 RPM pump uses an impeller
that is ½ the diameter, ¼ the mass and 1/16 the inertia. This creates a reduction in
required horsepower, a reduction in bearing loads and a reduction in materials to
manufacture. This will save you during the initial purchase of the pump, operating the
pump with a smaller engine and with lower maintenance costs. Learn more about how to save here.

This interactive relationship requires a systems approach to vibration analysis, rather
than the investigation of individual components. This article discusses the cause of
vibration, how is it measured and described, its limitations, and many other vibration
related issues. Click here to learn
