Pump Selection Notes

  1. Ordering these pumps requires a complete model code specifying seal and port options.
  2. Output flows listed are based on typical performance using 33 SUS (1,9 cSt) water glycol fluid at maximum pressure with pressurized inlet where required. Consult the Dynex sales department for a review of applications requiring operation below the Minimum speed of 1200 rpm.
  3. Models with the high pressure “H” option require the use of outlet port “A” (Autoclave/Butech fitting) or “B” (British Standard Pipe fitting). Pumps with ports for standard S.A.E. fittings are not recommended for operation above 8000 psi (560 bar). Contact the fitting manufacturer for the pressure rating of the fitting.
