4124A Series Cast Iron Internal Gear Pumps

4124A Series Cast Iron Internal Gear Pumps

4124A Series Universal Product Line Cast Iron Internal Gear Pumps

The Universal Product Line 4124A Series 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. 4124A Series 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 4124A Series Features & Benefits
• For adhesive processing, the positive displacement internal gear pump provides consistent, non-pulsating flow across a wide viscosity range, ensuring accurate metering and gentle handling to preserve material integrity and prevent shear degradation.
• 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.
4124A Series™
• Series designed with an enlarged bearing housing. Used in conjunction with a spacer coupling permits easy cartridge seal or O-Pro® Barrier Seal installation and removal in place without removing the head and rotor/shaft.
• Seal options include packing, O-Pro® Barrier Seal, single component seals, cartridge lip seals and cartridge single and double mechanical seals. Various seal flush plans are available.
