Model: CHD
The CENTFOS-CPP API 610 OH4 pump is a vertical in-line, single-stage centrifugal pump designed for refinery, petrochemical, gas processing, and industrial services. Its close-coupled OH4 design mounts the impeller directly on the driver shaft, creating a compact pump with simplified installation, reduced alignment needs, and reliable performance in demanding process conditions.
The CENTFOS-CPP, API 610 OH4 pump is a vertical in-line, single-stage centrifugal pump designed according to the latest edition of API 610 for refinery, petrochemical, gas processing, and general industrial process services.
The OH4 configuration features a close-coupled design, where the impeller is mounted directly on the driver shaft, eliminating the need for a separate coupling and bearing housing. This results in a compact footprint, reduced alignment requirements, and simplified installation, making OH4 pumps ideal for space-restricted process units and skid-mounted systems.
CENTFOS OH4 pumps combine optimized hydraulic performance, rigid construction, and API-compliant engineering to ensure reliable operation in demanding service conditions.
