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 at rated pressure with pressurized inlet where required.
  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.
