For heavy-duty operations involving high pressure and elevated temperatures across chemical processing, power generation, papermaking, natural gas treatment, crude oil transport, petrochemicals, and refineries, the JHBB/JHBD pump series offers reliable performance. It excels in transferring demanding media such as corrosive fluids, light hydrocarbons, and high-temperature substances across LNG plants, delayed coking units, alkylation processes, and vacuum or atmospheric distillation systems. Structurally, this equipment is a two-stage, radially split centrifugal pump with two-end support, built to API610-11th specifications. The series is divided by its first-stage design: JHBD offers double suction, while JHBB provides single suction. Discharge and inlet flanges are sized to ISO/ANSI codes. Additionally, the seal chamber strictly follows ISO21049/API682 standards, supporting the integration of non-pressurized tandem, pressurized tandem, or single cartridge seals. All auxiliary线路 (p…
