SEW - Lobe Pump

Applications & Use Cases

• Transferring viscous liquids and slurries such as sauces, creams, and doughs.
• Handling delicate products like fruit pieces or yoghurts without damage.
• Metering and dosing applications in food production lines.
• Circulating cleaning-in-place (CIP) solutions.

Typical Specifications

Typical capacity

For this class of equipment, capacities commonly range from a few hundred litres per hour up to several cubic metres per hour, depending on the lobe design and motor speed.

Power supply

Units of this type typically operate on a 3-phase industrial power supply, commonly 400V, 50Hz in the UK.

Materials of construction

Product-contact parts are generally constructed from food-grade stainless steel (e.g., 316L) to meet hygiene standards.

Viscosity range

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

Operating temperature

Commonly designed to operate within a temperature range suitable for food processing, typically from -10°C to +120°C, depending on seal materials.

Connections

Process connections are typically hygienic clamp (e.g., Tri-Clamp) or flanged, sized to match common food processing pipework.
