Features

  • Each pump features a variable Oil By Pass™ stroke adjustment mechanism which will allow better valve performance than variable linkage designs
  • Valve checks have extra time to seat even in heavy or viscous liquids since they are idle during the by-pass portion of the suction and discharge strokes
  • EZE-CLEAN™ valves are removable without disturbing piping (Exceptions: 500-E series and 560 series in PVC and PVDF construction)
  • 500 series pumps are available in Simplex and Duplex configurations and capacities can transfer up to 94 gallons per hour
  • 5005-S and 5003-S pumps are built to deliver very low flows that are repeatable and accurate, ranging down to quarts per day
  • 600 Series pumps are designed for high-volume, high-pressure applications
  • 6000 Series pumps are designed for low-volume, high-pressure applications
