Establish a common technical basis first: fluid, duty point, materials, sealing, driver and accessories. When replacing an installed pump, compare drawings, connections and interfaces. A standard designation or similar flow rate does not establish that replacement requires no modifications.
Organize costs over the chosen period: purchase, installation, energy, operation, maintenance, downtime and disposal. Use duty-point consumption, plant records and quoted prices. Life cycle costing helps compare scenarios; it does not guarantee savings or identify a winner by nationality.
Request delivery and sourcing information for critical components, together with service terms. An imported-equipment supplier may hold stock and provide support in Brazil; a Brazilian-made part may require manufacturing. Registration, testing and standard requirements need evidence within the contract scope, regardless of origin.
