Sulzer - Overhung Single Stage Process Pump

The Overhung Single Stage Process Pump is an API 610 (ISO 13709) Type OH2 horizontal, centerline-mounted, single-stage, radially split pump designed for demanding industrial applications. It offers the broadest performance range in its class and is commonly used in heavy-duty refinery, petrochemical, gas processing, and offshore oil production environments. Key features include a robust shaft for minimal deflection, finned bearing housing with fan cooling for extended bearing life, and heavy-duty baseplates with enhanced nozzle load options. The pump supports both electric motor and steam turbine drivers, and is equipped with ISO 21049 (API 682) cartridge-type mechanical seals for reduced emissions. Its construction allows for reliable operation in high-temperature and high-pressure services, including seawater boosting and vacuum gas oil handling.
