Pump Selection Notes

  1. Ordering these pumps requires a complete model code specifying seal and port options.
  2. Output flows are based on typical performance using 100 SUS (20 cSt) mineral oil at rated pressure with pressurized inlet where required. Consult the Dynex sales department for minimum inlet pressure and for a review of applications requiring continuous-duty at rated speeds higher than 1800 rpm or lower than 900 rpm.
