Large Capacity Horizontal Split Casing Centrifugal Water Pump

Different from ordinary end-suction pumps, BB1 pump adopts axial split casing and double-suction impeller between-bearing structure. It features balanced axial and radial forces, lower vibration, higher operational stability and easier maintenance. It fully complies with API 610 heavy-duty standards, suitable for 24/7 continuous industrial operation, while ordinary pumps are mostly for light-duty intermittent working conditions.

BB1 pump is mainly applicable to large-flow, medium-high pressure continuous fluid transmission scenarios. It is widely used in power generation plant water supply, petrochemical medium transportation, urban municipal water supply and drainage, district heating, industrial circulating water systems, fire-fighting water supply and flood control drainage, adapting to various non-corrosive and weakly corrosive low-viscosity fluid transportation.

Thanks to the axial split casing design, users can directly open the upper pump casing to inspect, repair or replace internal rotors, seals and wear parts without dismantling inlet and outlet pipelines or moving the motor. This design greatly shortens maintenance time, reduces equipment downtime, and avoids pipeline misalignment and leakage risks caused by repeated disassembly and assembly.

Firstly, the CFD-optimized hydraulic flow channel reduces fluid turbulence and transmission resistance loss. Secondly, the double-suction impeller balance design reduces mechanical friction and bearing load. In addition, its efficient working range covers most conventional operating conditions, ensuring the pump runs near the best efficiency point for a long time, effectively reducing power consumption and improving comprehensive energy efficiency.

It supports multiple customized configurations: various mechanical seal types (P11, P23, P32 and combined sealing solutions) for different temperature and pressure media; grease/oil dual bearing lubrication modes for high-speed and high-temperature working conditions; customized special materials for corrosive or impurity-containing media; horizontal/vertical installation forms and direct/universal shaft drive modes to meet diverse layout requirements.
