Watson-Marlow 620RA - Performance Data

24 Performance data
Note: Flow rates quoted have been rounded for simplicity, but are accurate to within 5% -well within the
normal tubing-tolerance variation of flow rate. They should therefore be taken as a guide. Real flow
rates in any application must be determined empirically.
Note: Two standard speed ranges are available as shown in the tables below. Other speed ranges are
