4224B Series Universal Product Line Cast Iron/Abrasive Liquids Internal Gear Pumps

The 4224B 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.

Viking Pump 4224B Series Features & Benefits
• 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; bushings provided a secondary point of radial shaft support.
• Rotatable bearing housing provides easy rotor end clearance adjustment to compensate for viscosity or 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
