SEW Lobe Pump

• Transferring viscous liquids and slurries in food processing, such as sauces, jams, and doughs.
• Handling shear-sensitive products in pharmaceutical and cosmetic industries, including creams and emulsions.
• Moving abrasive or corrosive fluids in chemical processing, like polymers and industrial waste.
• Dosing and metering applications requiring precise volume control in various manufacturing processes.

Typical capacity

For this class of equipment, capacities typically range from a few litres per minute up to several hundred cubic metres per hour, depending on model and application.

Power supply

Commonly found on units of this type are 3-phase industrial power supplies, typically 400V, 50Hz, often with variable speed drive compatibility.

Operating pressure

Lobe pumps are generally capable of discharge pressures up to 15-20 bar, suitable for many transfer and dosing tasks.

Materials of construction

Wetted parts are typically stainless steel (e.g., 304 or 316L) for hygiene and corrosion resistance, with various elastomer options for lobes and seals.

Viscosity handling

These pumps are well-suited for a wide range of viscosities, from thin liquids to highly viscous pastes, often up to 1,000,000 cP.

Footprint

The footprint for industrial lobe pumps varies significantly but is typically compact for their capacity, often requiring less than 1-2 square metres for the pump head and motor assembly.

• What are the main advantages of a lobe pump over other positive displacement pumps?

  Lobe pumps offer gentle product handling due to low shear, good for viscous and shear-sensitive fluids, and can handle solids in suspension without damage. They also provide consistent flow rates.

• Is this SEW Lobe Pump suitable for hygienic applications?

• What kind of maintenance is typically required for a lobe pump?

• Can this pump handle abrasive products?

• What flow control options are typically available?

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.
