Definition of Viking Rotary Lobe Pump
A Viking rotary lobe pump is a positive displacement pump that uses two symmetrically rotating lobe-shaped rotors to gently and efficiently transfer fluids without deforming or damaging the product structure. It is an ideal pumping solution for handling low- to high-viscosity liquids, fluids containing solid particles, and sensitive products in the food, pharmaceutical, beverage, and chemical industries.
Operating Principle of Viking Rotary Lobe Pump
The operation of a Viking rotary lobe pump is based on the positive displacement principle. Lobe-shaped rotors rotate inside the pump chamber to create sealed cavities for fluid intake and transfer:
- Fluid suction: As the rotors rotate, the volume at the inlet increases, creating negative pressure that draws fluid into the pump chamber.
• Containment and transfer: The fluid is trapped in the space between the lobes and the pump casing and is carried along the rotational path toward the discharge port.
• Fluid discharge: As the cavity volume decreases at the outlet, the fluid is discharged with stable pressure.
• Rotor synchronization: The two rotors are driven by external timing gears, ensuring non-contact operation and smooth, quiet performance.

Structure of Viking Rotary Lobe Pump
Viking rotary lobe pumps feature a sophisticated yet efficient design, consisting of the following main components:
| Component | Function & Description |
| Lobe Rotors | Create pumping chambers and transport fluid. Available in bi-wing, tri-lobe, or multi-lobe designs depending on the model. |
| Pump Casing | Encloses the pumping chamber; typically made of 316L stainless steel for corrosion resistance and hygienic compliance. |
| Gearbox & Timing Gears | Synchronize the two rotors, ensuring non-contact operation and smooth performance. |
| Seals & Gaskets | Provide leak-tight sealing; designed for easy replacement (front-loading seals). |
| Shafts & Bearings | Support stability and power transmission; bearings are located outside the pump chamber to extend service life and increase load capacity. |
| Inlet & Outlet Ports | Available in ANSI / DIN / 3A standard sizes, compatible with modern piping systems. |
Advantages of Viking Rotary Lobe Pumps
✅ Capable of handling large solid particles without damaging the product, as the lobes do not contact each other.
✅ Hygienic design with CIP/SIP capability, making them ideal for food and pharmaceutical industries.
✅ Suitable for pumping a wide range of materials such as viscous fluids, adhesives, greases, or fluids containing large particles.
✅ Smooth operation with steady flow and minimal pulsation.
✅ Self-priming capability when the pump chamber is wet, eliminating the need for auxiliary priming pumps in certain applications.
Practical Applications of Viking Rotary Lobe Pumps
- Food & Beverage industry: syrup, jam, chocolate, fruit juice, milk, soy sauce, edible oils.
- Pharmaceuticals & cosmetics: gels, creams, light and heavy solvents, viscous fluids.
- Chemical industry: polymers, chemical emulsions, mild acids with compatible materials.
