In the figures and tables, except for Figures 2 and 5 and Tables 2 and 5 (shaft end with tang drive), the diameter d 2 corresponds to the diameter d specified in ISO 6519. NOTE The flange configuration can optionally be rotated relative to the pump housing. 4.2 High-pressure supply pumps 4.2.1 Type 1 end-mounting flange See Figure 1 and Table 1.BS ISO 7299-2 pdf download.
