Built to satisfy the 11th edition of API610, the JHBB and JHBD series are dual-end supported, radially split centrifugal pumps operating across two stages. Distinguishing the two variants, the JHBB model employs a single-suction configuration for its initial stage, whereas the JHBD variant is engineered with a double-suction first stage. Both suction and discharge flange measurements are fully aligned with ISO or ANSI dimensional standards.
In accordance with ISO21049 and API682 guidelines, the seal chamber architecture allows for the straightforward integration of non-pressurized tandem seals, pressurized tandem seals, or single cartridge mechanical seals. Furthermore, all auxiliary piping connections—including those for buffer, quenching, heating, cooling, and flushing—strictly follow API plan configurations.
These pumps are ideal for managing high-temperature, corrosive, and light hydrocarbon fluids. They are frequently integrated into systems like LNG facilities, delayed coking,…
