4124B / 4224B Series Viking Universal Pump Product Line details

The 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. The Universal Product Line is Viking Pump’s most versatile line of internal gear pumps due to the availability of many design and material options.

• 4124B Series™: The 4124B series heavy duty internal gear pumps have Behind the Rotor dynamic shaft seals. By locating the mechanical seal immediately behind the rotor, this prevents the shaft and bracket bushing from coming into contact with the liquid.

• 1124A Series™, 1124AE Series™, 1324A Series™: This NEW Universal Seal Product Line comes with the O-Pro Barrier Seal factory installed. The Universal Product Line combines the tested reliability of the Universal pump & O-rings to create a robust seal and lubrication chamber, all in one. Viking Pump is the leader in internal gear innovation and the latest development is the O-Pro™ Seal technology.

• 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
