Product Description

Product Description

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, according to standards, each with its own focus.
BB1: Suitable for general industrial processes and sewage treatment, with a simple structure and easy maintenance.
BB2: Suitable for high-temperature and high-pressure working conditions such as refining and petrochemicals, it can transport corrosive or flammable and explosive media with solid particles.
BB3: Suitable for heavy industry scenarios such as petroleum refining and chemical processing, with high flow and high pressure output.
BB4: Suitable for high-temperature and high-pressure liquid transportation, particle media should be avoided.
BB5: Suitable for high pressure and high temperature scenarios such as boiler feedwater in power plants, resistant to high pressure and high temperature.

BB1 series chemical pump

Typical applications: Lean solution pump, rich solution pump, and hydraulic turbine in large-scale synthetic ammonia plants, and main pump for pipeline transportation in crude oil or refined oil transportation projects.
Structural features: Axial splitting, single-stage or two-stage, volute shell type, supported at both ends, easy to maintain.
Application scope: Suitable for cleaning or neutral/corrosive media containing trace particles, such as industrial processes, sewage treatment, crude oil transportation, etc.
Performance parameters: flow rate up to 5500 m ³/h, head 550 m, speed 3580 r/min, working pressure 5.17 MPa (G), temperature range -100 ℃~+450 ℃

BB2 series chemical pump

Typical applications: High temperature tower bottom pumps such as flash bottom oil and constant bottom oil in refining units, semi lean liquid pumps and rich methanol pumps in coal chemical units.
Structural features: radial splitting, double vortex shell, single-stage single suction or double suction impeller, designed for high temperature, high pressure, and low temperature working conditions.
Application scope: Refining, petrochemical, coal chemical, natural gas processing, etc. It can transport corrosive or flammable and explosive media with solid particles.
Performance parameters: flow rate up to 5500 m ³/h, head 550 m, speed 3580 r/min, working pressure 5.17 MPa (G), temperature range -100 ℃~+450 ℃

BB3 series chemical pump
