123C Series Universal Product Line Steel Externals Internal Gear Pumps
The 123C Universal Product Line has the broadest range of sealing options of all pumps built by Viking Pump®. The U-Plus™ bracket design accepts packing as well as numerous component and cartridge seals.
123C Series Viking Pump's most versatile line of internal gear pumps with many design and material options. 123C pumps are available with the ProPort™ casing and a wide variety of flange types and sizes as well as both 90 degree and opposite port arrangements* enabling flexibility when connecting pumps to piping. *90 degree port arrangements available in sizes H-Q.
• In crude oil transfer, the positive displacement internal gear pump provides reliable, non-pulsating flow across varying viscosities and temperatures, ensuring consistent delivery even with waxy, abrasive, or high-solid content.
• ProPort™ Casing (123C Series™): » Adaptable port design offers a variety of ports sizes and types, enabling flexibility when connecting pumps to piping. » H-Q sizes available with optional opposite porting. » Casing drain allows the pump to be drained without removing the head. » Optional O-ring joint seals for high pressure or difficult to seal applications. » Internal circulation promotes flow behind the rotor.
• U-Plus™ Bracket (123C Series™): » Seal options include packing, single component seals, cartridge lip seals and cartridge single and double.
mechanical seals. » Stainless steel window guards offer protection from rotating parts.
• Footed one-piece steel bracket provides rigid mounting to help maintain alignment, which extends seal and bearing life.
• 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.
• Axial rotor thrust is controlled by double row ball bearing or tapered roller bearings; bushings provide 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.
• Can use direct drive, gear reducer or gearmotor drive, or belt-drive.
• Pressure relief valve standard on non-jacketed pumps; less valve / plain head option available.
