Features and Benefits of the Viking 4126A 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 ductile 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; less valve / plain head option available
• Series designed with an enlarged bearing housing.
• Used in conjunction with a spacer coupling permits easy cartridge seal installation and removal in place without removing the head and rotor/shaft.
• Seal options include packing, single component seals, cartridge lip seals and cartridge single and double mechanical seals. Various seal flush plans are available
