Pump Selection Notes

  1. Please refer to product literature for complete specifications including seal and port options.
  2. Output flows are based on typical performance at rated pressure with pressurized inlet where required.
  3. High pressure models 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.
  4. These pumps are not bi-directional. Rotation must be specified, viewed from the shaft end.
  5. Electrohydraulic remote control can be achieved using a Dynex Remote Proportional Actuator (RPA) to stroke the volume control stem.
