Vogel sang - 2023 Vogel sang Rotary lobe pump

• Transfer of municipal and industrial wastewater, including sludges and slurries.
• Handling of viscous fluids and those containing solids in food processing and chemical industries.
• Dosing and transfer of challenging media in biogas plants and agricultural applications.
• Circulation and transfer duties in various industrial processes requiring gentle product handling.

Typical capacity

Rotary lobe pumps of this class typically offer flow rates ranging from a few cubic metres per hour up to several hundred, depending on the specific model and application.

Power supply

Commonly found on units of this type are three-phase industrial power supplies, typically 400V, 50Hz, suitable for UK industrial environments.

Operating pressure

Typically, these pumps can achieve discharge pressures up to 10-15 bar, suitable for transferring fluids over distances or against moderate head.

Materials of construction

For waste handling, wetted parts are commonly made from robust materials such as cast iron, stainless steel, or elastomers, selected for wear resistance and chemical compatibility.

Footprint

The compact design of rotary lobe pumps generally allows for relatively easy integration into existing plant layouts, with dimensions varying significantly by capacity.

Maintenance requirements

Units of this type are typically designed for ease of maintenance, often featuring quick-change lobes and seals to minimise downtime.

• What types of solids can this pump handle?

  Rotary lobe pumps are well-suited for handling fluids containing a significant percentage of solids, including fibrous materials and larger particles, due to their large free passages and gentle pumping action. Buyers should confirm the maximum solid size for this specific unit with the seller.

• Is this pump suitable for abrasive media?

• What are the advantages of a rotary lobe pump over other pump types for waste materials?

• How does the 'used' condition affect performance and lifespan?

• Can this pump be used for dosing applications?

Food processing pumps are valued for reliability and durability in continuous operations. Buyers typically prioritise corrosion resistance, hygiene compliance, and consistent flow rates. When purchasing used units, inspecting seals, impellers and motor condition proves essential. Industry sentiment favours models with straightforward maintenance requirements and availability of spare parts. Stainless steel construction and gentle handling capabilities for delicate products are consistently sought features.
