SEW - SEW Lobe Pump

Applications & Use Cases

• Transferring viscous fluids in food processing, such as sauces, jams, and doughs.
• Handling shear-sensitive products in pharmaceutical and cosmetic manufacturing.
• Pumping slurries and wastewater in environmental applications.
• Metering and dosing chemicals in industrial processes.

Typical Specifications

Typical capacity

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

Power supply

Units of this type typically operate on three-phase industrial power, commonly 400V, 50Hz in the UK.

Operating pressure

Lobe pumps are generally suitable for pressures up to 15-20 bar, though specific models may vary.

Viscosity range

They are particularly effective with highly viscous fluids, often handling viscosities up to 1,000,000 cP or more.

Materials of construction

Wetted parts are commonly stainless steel (e.g., 316L) for hygiene-critical applications, with various elastomer options for lobes and seals.

Typical footprint

The footprint can vary significantly, from compact skid-mounted units to larger standalone pumps, typically requiring 0.5m² to 2m².

Maintenance requirements

Maintenance typically involves periodic inspection and replacement of seals and lobes, which are generally designed for easy access.

Frequently Asked Questions

• What is a lobe pump?

  A lobe pump is a type of positive displacement pump that uses two or more rotating lobes to create a vacuum, drawing fluid into the pump and then forcing it out. They are known for their gentle handling of fluids.
