• Capacities to 345 m³/hr
• Differential pressures to 17 bar
• Viscosity range 1 to 440,000 cSt
• Maximum temperature 425°C

1. Universal Seal Internal Gear Pumps: Heavy duty, foot-mounted pumps with enlarged bearing housing lets user replace seals or change seal technologies without removing pump.
2. Universal Mag Drive Internal Gear Pumps: Dimensionally interchangeable, sealless mag drive pumps for crucial liquid containment applications.
3. Motor Speed Series Internal Gear Pumps: Capable of operating at 8 pole, 6 pole and 4 pole motor speeds, this metric designed pump may be foot-mounted or close coupled to IEC frame motors for a compact footprint in a high capacity pump.
4. General Purpose Internal Gear Pumps: General purpose pumps for medium duty applications.
5. Internal Gear Pumps for Special Applications: Viking designs and builds custom pumps with special features for specific applications and OEMs.
6. API 676 Internal Gear Pump: The Viking XPD 676 Series of internal gear pumps is designed to API 676 standards.
7. Lid-ease Strainers: Viking provides a variety of lide-ease strainers to compliment their pumps.

External Gear Pumps

Viking's SG range of spur gear design external gear pumps are designed for high pressure pumping in low capacity applications. SG pumps deliver longer seal and bearing life by preventing shaft movement and wear that cause competitors' pumps to fail prematurely.

SG Series Pumps were designed to ensure reliability in industrial process applications. Because seal leakage is the most frequent cause of pump downtime, the SG Series minimizes shaft movement to significantly lengthen seal life. Radial (side-to-side) movement or misalignment is prevented by close coupled motor mounts or outboard bearings for foot mounted pumps. Axial (back-and-forth) movement is minimized by spur type gears, instead of helical gears which cause gear thrust on mating components. As standard equipment, the SG Series' anti-friction needle bearings eliminate wear that journal bearings experience at startup and shutdown - when the hydrodynamic film of liquid is absent. SG Series pumps have an extensive range of options to ensure the right seals, bearings and other features for the application.

• 29 sizes
• C-flange, foot bracket or base mounting options
• Ductile iron or cast iron construction
• Lip seal, mechanical seal and Mag Drive options
• Capacities to 45 m³/hr
• Differential pressures to 172 bar
