FBCN Centrifugal Pumps in Passa Quatro

Every FB pump leaves the factory with a warranty against manufacturing defects, under the terms detailed in the commercial proposal. The condition is that installation, operation and maintenance respect the manual's parameters and the sizing defined by engineering. For details on your project in Passa Quatro, talk to our technical team.

Four pillars: a current Petrobras CRCC registration for Oil & Gas; API 676 (positive displacement) on the FBE series; ASME B73.1 (process centrifugals) on the FBCN series; and NFPA 20 / NBR 16704 compliance for stationary fire pumps.

Yes. On pumps installed in Passa Quatro, FB Bombas application engineering applies ISO 10816 (velocity RMS in mm/s) to diagnose misalignment, imbalance, bearing defects and cavitation. The scope covers baseline captured at startup, spectral comparison throughout PM campaigns and recommendation of interventions — re-balancing, bearing replacement, laser alignment — before the machine reaches the standard's zone D.

It depends on the configuration: standard-arrangement pumps have shorter lead times, while special constructions follow the schedule stated in the technical proposal. The deciding factor is the combination of series, materials and stock availability — and transport to Passa Quatro goes through our regular road operator.

Yes. The design of the FBE and FBCN lines favors direct access to wear-prone components — disassembly and inspection are done with conventional tools. The routine gets even simpler with detailed technical manuals and replacement parts supplied straight from the factory.

Yes — with a structural advantage: since the FBE, FBEI, FBCN and FBOT series are manufactured entirely in Brazil, parts ship from the factory itself in Cabreúva/SP, with short lead times for planned shutdowns and priority handling for emergencies. The direct effect is a lower total cost of ownership.

Yes. The FBCN series complies with ASME B73.1 (North American standard for horizontal end-suction process centrifugal pumps) — which enables retrofit on existing baseplates in Passa Quatro plants, whoever manufactured the installed unit, provided the dimension designation matches. Shaft dimensions, suction/discharge flanges, casing feet and impeller centerline follow the standard: the complete FBCN pump goes in and piping and baseplate stay put.

The FB line covers a wide range: mineral and synthetic oils, asphalt (CAP), BPF fuel oils, petroleum derivatives, molasses, resins, viscous chemical and hydraulic products (FBE series); raw and treated water, process fluids, industrial effluents (FBCN series); thermal oil at elevated temperatures (FBOT series). Each application is sized according to fluid viscosity, temperature and chemical compatibility.

The FB Bombas rotating set is balanced per ISO 21940 G2.5 (a balancing grade equivalent to API 610 requirements for heavy-duty service) — required for critical projects in Passa Quatro with continuous regime, plants with online vibration monitoring or applications with high cost of unplanned downtime. For machines running above 3,600 RPM or with rotating mass over 50 kg, balancing is performed on two planes with a piezoelectric sensor.
