Pumps & Fluid Handling replacement guide
Identify pumps and fluid-handling parts by model, duty point, fluid, materials, connection, and operating conditions.
Evidence boundary. Pump replacement is an application decision, not a model-number-only decision. The guide follows the same compare-before-claim standard used for gearboxes.
