Pump Selection Notes

  1. Ordering these pumps requires a complete model code specifying seal and port options. Please refer to product literature for complete specifications.
  2. Output flows are based on typical performance using 100 SUS (20 cSt) hydraulic oil at rated pressure with pressurized inlet where required. Consult the Dynex Sales department for a review of applications requiring continuous-duty at rated speeds higher than 1800 rpm or lower than 900 rpm.
  3. Models with the high pressure “H” option require the use of outlet port “A” (Autoclave/Butech fitting) or “B” (British Standard Pipe Parallel fitting). Pumps with ports for standard SAE fittings are not recommended for operation above 8000 psi (560 bar). Pumps with ports for BSPP fittings are not recommended for operation above 10 000 psi (700 bar). Contact the fitting manufacturer for the pressure rating of the fitting.
