Model: CMZ
The CENTFOS-CMZ API 610 BB1 pump is a between-bearing, axially split centrifugal pump designed for refinery, petrochemical, pipeline, and offshore applications. Its robust BB1 configuration ensures high reliability, reduced shaft deflection, and stable hydraulic performance. Built for continuous-duty service, it delivers durable, efficient operation in critical industrial process environments.
The CENTFOS-CMZ, API 610 BB1 pump is a between-bearing, axially split, single or double-stage centrifugal pump designed in accordance with the latest edition of API 610 for critical refinery, petrochemical, pipeline, and offshore applications.
The BB1 configuration is engineered for high reliability, hydraulic stability, and long service life under demanding operating conditions. With its horizontally split casing and between-bearing rotor design, the BB1 pump provides superior mechanical strength, reduced shaft deflection, and excellent hydraulic performance compared to overhung pump designs.
CENTFOS BB1 pumps are designed for continuous-duty service and built to meet stringent international standards for performance, safety, and durability in mission-critical process operations.
