Pump Selection Notes

  1. Please contact the Dynex sales department for a complete model code to order these pumps.
  2. Output flows are based on typical performance at rated pressure with pressurized inlet where required. PV4000 Series 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.
  3. These models are for clockwise rotation (viewed from shaft end).
