DYNEX PF1300 SERIES FIXED DISPLACEMENT CHECKBALL PUMPS
FOR WATER-BASED FLUIDS

0.31 to 1.42 gpm (1,17 to 5,37 L/min) at 1800 rpm
Maximum: 15 000 psi (1040 bar)

  • A wide range of fluid compatibility, for reliable operation with low-lubricity, low viscosity fluids.
  • Bi-directional rotation providing constant flow direction regardless of drive shaft rotation.
  • Shaft Options: Standard keyed, Optional spline.
  • Seal Options: Standard Fluorocarbon, Optional EPR seals for use with some phosphate ester fluids, or Fluorocarbon with high pressure shaft seal.
  • Single-fluid design eliminates the need for a lubrication circuit.

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 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 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.
