Specifications of Viking Rotary Lobe Pumps

Viking rotary lobe pumps are positive displacement rotary gear pumps manufactured in the United States, widely recognized in industries requiring high accuracy, long service life, and reliable handling of high-viscosity liquids. The pumps are designed and produced in accordance with stringent European and international standards.

Basic Technical Specifications of Viking Rotary Lobe Pumps

Some common specifications of Viking rotary lobe pumps (may vary by model):

• Flow rate: from a few liters per minute up to more than 189 m³/h
• Operating pressure: up to approximately 17 bar (higher for certain series)
• Fluid viscosity: up to hundreds of thousands of cP
• Operating temperature: from –40°C to 180°C
• Pump casing material: stainless steel
• Connection types: flange, threaded, clamp (depending on application)

Thanks to this wide operating range, Viking rotary lobe pumps are suitable for both standard and specialized industrial applications.

Common Types of Viking Rotary Lobe Pumps

Viking rotary lobe pumps have been developed in multiple series to suit different operating environments and fluid characteristics.

Standard Viking Rotary Lobe Pumps

• Used in food, pharmaceutical, and chemical industries
• Simple structure, easy maintenance
• Suitable for continuous operation systems

Viking Rotary Lobe Pumps for High-Viscosity Fluids

• Designed for molasses, adhesives, chocolate, molten plastics
• Stable pumping performance with minimal pulsation
• Effectively reduces internal slip

Viking Rotary Lobe Pumps for Chemical Applications

• Pump casing and shafts made of stainless steel
• Excellent corrosion resistance
• Suitable for chemicals, solvents, and mild acids

Viking Rotary Lobe Pumps for the Food Industry

In addition to common industrial applications, Viking rotary lobe pumps are also widely used in the food industry when properly selected with configurations and materials that meet food safety requirements. Thanks to the positive displacement pumping principle, these pumps provide stable flow with minimal pulsation and are suitable for fluids ranging from low to high viscosity.

In food processing, Viking rotary lobe pumps are commonly used to pump:

• Syrups and molasses
• Molten chocolate
• Milk, cream, and dairy products
• Sauces and liquid seasonings

To meet food safety requirements, Viking rotary lobe pumps used in food applications are typically manufactured from stainless steel and designed for easy cleaning, minimizing product retention and dead zones. These features comply with international hygiene standards such as FDA 21 CFR 177, 3-A Sanitary Standards, and EHEDG, which are widely applied in the food processing industry.

Selecting the correct materials, design, and pump configuration is essential to ensure product quality, hygiene safety, and long-term operational efficiency in food production lines.

Limitations of Viking Rotary Lobe Pumps

Despite their many advantages, Viking rotary lobe pumps are not always the optimal solution for every application.

Higher Initial Investment Cost

Compared to conventional pumps, Viking rotary lobe pumps typically involve:

• Higher initial investment
• Greater suitability for medium to large-scale industrial systems

Correct Model Selection Is Critical

• Incorrect material selection or improper configuration can significantly reduce pump service life
• Technical consultation is recommended prior to installation

Practical Applications of Viking Rotary Lobe Pumps

Thanks to their stable and accurate pumping performance, Viking rotary lobe pumps are widely used in:

• Food industry (syrups, chocolate, edible oils)
• Pharmaceutical and cosmetic industries
• Paints, printing inks, and industrial adhesives

When Should You Choose a Viking Rotary Lobe Pump?

You should consider using a Viking rotary lobe pump when:

• Pumping high-viscosity fluids
• Stable and precise flow control is required
• The system operates continuously over long periods
• Durability and reliability are prioritized over initial investment cost

Conclusion

Viking rotary lobe pumps are a premium industrial pumping solution suitable for applications requiring high precision, durability, and the ability to handle complex fluids. Although they involve higher initial costs and require proper operating conditions, when the correct model and configuration are selected, Viking rotary lobe pumps deliver long-term, stable, and efficient performance for industrial users.
