Omac B440 Lobe pump

• Transfer of viscous liquids and slurries in food processing, such as sauces, yoghurts, and purees.
• Handling shear-sensitive products in pharmaceutical and cosmetic manufacturing.
• Metering and dosing applications where precise flow control is required.
• Transfer of challenging fluids in chemical processing, including those with suspended solids.

Typical capacity

For this class of lobe pump, capacities typically range from 5 to 50 cubic metres per hour, depending on product viscosity and system pressure.

Power supply

Units of this type commonly require a 3-phase electrical supply, with motor power often between 5.5 kW and 22 kW.

Construction material

Lobe pumps for hygienic applications are typically constructed from 316L stainless steel for wetted parts, ensuring corrosion resistance and ease of cleaning.

Inlet/Outlet connections

Commonly found with hygienic connections such as DIN, SMS, or Tri-Clamp, with sizes typically ranging from 50mm to 150mm.

Operating temperature

These pumps are generally designed to operate with product temperatures from -10°C to +120°C, suitable for CIP (Clean-in-Place) processes.

Pressure capability

Lobe pumps can typically achieve discharge pressures up to 10-15 bar, making them suitable for transfer over moderate distances or through heat exchangers.

• What is the primary advantage of a lobe pump over other pump types?

  Lobe pumps excel at handling high-viscosity, shear-sensitive, and particulate-laden fluids without causing damage to the product. Their non-contacting rotors minimise wear and product degradation.

• Are Omac B440 pumps suitable for hygienic applications?

• What maintenance is typically required for a lobe pump?

• Can this pump handle products with solids?

• What should I consider regarding the motor specification?

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.
