# Boosters

FluidFlow includes a comprehensive database of the following boosters: 1. Centrifugal Pumps. 2. Rotating Positive Displacement Pumps. 3. Fans & Compressors. 4. Positive Displacement Pumps & Compressors. Users can add new models to this database, a task which you only need to complete once. The new booster will then be stored in the database and will be available for all future modelling projects. From v3.31 onwards, FluidFlow allows you to automatically size all components available on the Boosters tab. If you are having any difficulty adding new models to the database, contact support at: support@fluidflowinfo.com.
