FBCN Centrifugal Pumps in Riacho das Almas

ISO 21940 G2.5 is the grade applied to the rotating set of FB Bombas pumps — direct equivalence with what API 610 asks for heavy-duty service. Critical projects in Riacho das Almas depend on this standard: continuous-regime operation, online vibration monitoring at the plant or high cost tied to unplanned downtime. When rotation exceeds 3,600 RPM or rotating mass goes over 50 kg, two-plane balancing is executed using a piezoelectric sensor.

Yes. FB Bombas is a Brazilian industrial-pump manufacturer since 1944, with a factory in Cabreúva/SP and a technical team for projects in Riacho das Almas. The FBCN (centrifugal), FBE/FBEI (gear) and FBOT (thermal oil) series cover the same applications served by imported equipment — with advantages in lead time (no import), direct factory technical support, spare parts for FB pumps themselves and Portuguese-speaking application engineering. In a normalized centrifugal retrofit, ASME B73.1 requires that units of the same standard dimension designation, from any source of supply, be interchangeable as to mounting dimensions, suction and discharge nozzles, input shaft and foundation bolt holes.

Yes. A complete technical Data Book accompanies each FB Bombas pump that reaches Riacho das Almas: hydraulic test certificate, material certificates (stainless steel, duplex and ductile cast iron per spec), ISO 21940 G2.5 balancing report, characteristic curve measured on the test bench, API 682 mechanical-seal data sheets, operation and maintenance manual and as-built drawings. The unit serial number traces all this documentation.

Yes. On pumps installed in Riacho das Almas, 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.

They do. The FBCN series dimensionally meets ASME B73.1, the North American standard for horizontal end-suction process centrifugal pumps. In practice, a Riacho das Almas plant running a normalized pump of the same designation achieves retrofit on the already-installed baseplate: since shaft dimensions, suction/discharge flanges, casing feet and impeller centerline follow the same standard, the FBCN pump takes the place of the previous one — piping and baseplate stay intact. Hydraulic equivalence (Q×H and NPSH) is checked separately, on the data sheet.

Yes. The FBE and FBCN lines were designed with easy access to wear-prone components, allowing disassembly and inspection with conventional tools. Detailed technical manuals and direct factory replacement parts availability simplify maintenance routines.

Who serves Riacho das Almas is the FB Bombas factory team itself in Cabreúva/SP. In practice: direct access to application engineering for sizing, a complete technical quotation returned within 3-5 business days and original parts supplied at factory pricing. Depending on project criticality, on-site technical visits to Riacho das Almas are added to the plan.

Since 1944 — over 82 years of continuous experience manufacturing industrial pumps. In Cabreúva/SP, the factory brings engineering, manufacturing and testing together under one roof, which assures total quality control on each unit shipped to Riacho das Almas and all across Brazil.

The schedule is set by three factors: chosen series, construction materials and stock at order time. Standard configurations ship faster; custom ones receive a firm date in the technical proposal. Delivery to Riacho das Almas is by road, shipping directly from the factory.
