BB Series Chemical Pump
The BB series chemical pump is a centrifugal pump designed specifically for harsh working conditions such as chemical and petroleum industries. It is divided into five models, BB1 to BB5, each optimized for specific applications.
Suitable for general industrial processes and sewage treatment. Features an axial splitting, single-stage or two-stage volute shell type supported at both ends. Ideal for cleaning or neutral/corrosive media containing trace particles.
Designed for high-temperature and high-pressure conditions in refining and petrochemicals. Radial splitting with double vortex shell, capable of transporting corrosive, flammable, or explosive media with solid particles.
Focused on heavy industry scenarios like petroleum refining and energy production. Axial splitting with symmetrical multi-stage impellers and dual suction design for high flow and pressure output.
Optimized for high-temperature and high-pressure liquid transportation. The pump casing is divided into upper and lower sections to ensure maximum safety. Granular media should be avoided.
Built for extreme high-pressure and high-temperature scenarios such as power plant boiler feedwater. Features a double-layered shell design where the inner layer can be extracted for maintenance.
