Viking's Heavy-Duty Internal Gear Pumps move liquids in hundreds of thousands of applications throughout the world. That's because they combine the simple and reliable operation with the problem-solving flexibility inherent in the "gear-within-a-gear" pumping principle. Viking Internal Gear Pumps are available in a variety of materials, port configurations, and sealing options and are individually built and hand-assembled to your exact application requirements for long service life and maximum performance.

The Heavy Duty series pumps offer thrust control for higher pressure capabilities than the General Purpose series, and adjustable rotor clearances to compensate for wear and viscosity.

Sealing options include:

• packing
• component mechanical seals

Available without jacketing, with head and bracket jacketing, or fully jacketed including the casing. Ports are available in a variety of 90- and 180- degree configurations. Integral pressure relief valves are standard.
