  • Manually adjustable stroke length provides accurate pump output adjustment
  • NEMA 4X / IP65 enclosures for protection against corrosive environments
  • Time tested electronics for reliable, repeatable performance
  • Totally encapsulated electronics for protection against moisture and corrosive conditions
  • Inputs for low level switch available on certain models
  • Models with external pacing for flow proportional applications
  • Advanced control options for simplified system integration (pulse multiply/divide, 4-20 mA, remote on/off)
  • *UL, *CUL, NSF 50, NSF 61, *CE Certifications
  • Four Function Valve
  • AUTOPRIME™ liquid End
  • High Viscosity Liquid End
