Chemical Pumps


Model A9


Model A7


Model A7 NM


Designed to provide for high production with maximum reliability

  • 70-80% of pump maintenance is related to seals.
  • Wilfley’s chemical pumps are designed with maximum seal flexibility.
  • The Wilfley dynamic seal and a selection of mechanical seals are available to meet your needs.
  • The Wilfley dynamic seal can accommodate difficult applications:
    • Varying amounts of solids
    • Solutions close to saturation that crystallize
    • Low NPSH with intermittent cavitation.
  • The Wilfley dynamic seal has no rubbing parts so no continuous seal water is required.
  • This means NO PRODUCT DILUTION and the ability to be RUN DRY.
  • Robust heavy duty construction that weighs 35-50% more than most ASME specified pumps.
  • Heavier hydraulic parts and minimal shaft deflections mean HIGHER reliability and LOWER maintenance costs.
