4126A Series Universal Product Line Ductile Iron Internal Gear Pumps
The 4126A Series Universal Product Line has the broadest range of sealing options of all pumps built by Viking. The stuffing box on all sizes accepts packing, numerous component single mechanical seals, or a wide variety of cartridge seals. 4126A pumps Universal Product Line is Viking Pump’s most versatile line of internal gear pumps due to the availability of many design and material options.
Viking Pump 4126A Series Features & Benefits
• For refined fuel transfer, the positive displacement internal gear pump ensures accurate, pulse-free flow with tight volumetric control, accommodating low-viscosity hydrocarbons while minimizing vapor formation and leakage risk.
• 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.
