Description
The BB4 Series MSH/HD/DG is a multi-stage, single-suction ring-section horizontal pump engineered for demanding hydrocarbon, chemical, water, and seawater services. With investment-cast diffusers and channel rings for consistent hydraulic performance, each impeller is individually balanced to ensure smooth operation. Center-line mounting and a self-venting casing accommodate thermal expansion without distortion, while serrated running clearances minimize internal leakage. The carbon-steel bearing housing is API 682–ready for mechanical seals, and balance discs (or optional balance drum) tailor axial thrust control to your application. Rated for flows up to 300 m³/h (1,320 gpm), heads to 1,200 m (3,940 ft), pressures to 150 bar (2,175 psi), and temperatures from –50 °C to 200 °C (–58 °F to 400 °F), the BB4 series delivers reliable, efficient performance across power, chemical, pulp & paper, irrigation, and general-industry pump duties.
