HSA axially split single stage between bearing pump

Reliability and efficiency for critical services

The HSA API 610 (ISO 13709) Type BB1 is an axially split, single stage, horizontal, double suction, between bearing pump. The Sulzer HSA product range is ideal for long term continuous running services in refineries and pipelines. Its robust casing and custom hydraulics are specifically designed to ensure maximum availability and reduced total life cycle costs. The HSAv with its vertical shaft is used offshore where deck space is limited.

Applications
  • Auxiliary applications
    The complex processes performed on a typical FPSO rely on the performance of dozens of pumps handling a variety of liquids under widely varying process conditions.

  • Crude oil offloading
    Depending on the FPSO design, a booster pump is often required to export crude oil delivered to deck level by the FPSO cargo system.

  • Firewater systems (fire fighting)
    Firewater pumps are the heart of an FPSO’s firefighting system. It is vital that the pumps be reliable in extreme conditions and run for extended periods of time.

  • Seawater lift
    Sulzer builds both lineshaft and submersible motor vertical seawater lift pumps. Sulzer SMHv and SMDv pumps are vertical shaft in BB1 casing.
