    Installation, Operation and Maintenance Manual ® CD, HL & NC Ranges of Dri-Prime Pumps 6.2 Alignment The following notes provide general guidance on alignment and its elimination. It is normal practice to carry out any adjustment to alignment by moving the driver – not the pump. In designing any structure to support the pump set allow an additional 0.25mm (0.010”) extra height difference between pump and driver support for shimming purposes.
  • Page 9: General Installation Notes

    These are also the responsibility of the installer. The Godwin Dri-Prime pump range is designed to operate on long lengths of suction pipe but it is always advisable to position the pump as close to the source as possible.
