Features and Benefits of the Viking 4124A Internal Gear Pump.

  • Positive Displacement Internal Gear pumping principle handles a broad range of viscosities with constant flow rate

  • Axial rotor thrust is controlled by double row ball bearing or tapered roller bearings; a bushing provides a secondary point of radial shaft support
  • Rotatable bearing housing provides easy rotor end clearance adjustment for viscosity or to compensate wear
  • Numerous material options are available for bushings, idler pins, shafts, rotors, idlers and elastomers
  • Gear and pump geometry has been optimized based on more than 100 years of experience
  • Footed cast iron bracket provides rigid mounting to help maintain alignment, which extends seal and bearing life
  • Can use direct drive, gear reducer or gearmotor drive, or belt-drive
  • Pressure relief valve standard on all except RS size pumps; less valve / plain head option available
  • 124A, 124AE, 4124A, 4124AE, 324A, 4324A:
