LR CR-210 Vacuum pump

• Used in vacuum packaging systems to remove air from food products, extending shelf life.
• Applied in de-aeration processes for viscous food products like sauces, purees, and batters to improve texture and appearance.
• Integrated into vacuum cooling systems for baked goods and other food items to rapidly reduce temperature.
• Utilised in evaporation and concentration processes for liquid food products, operating under reduced pressure.

Pump Type

Liquid ring vacuum pump, known for handling vapours and liquids without damage.

Typical Motor Power

For this class of equipment, motor power commonly ranges from 5.5 kW to 15 kW, with this unit featuring a 7.5 kW motor.

Typical Vacuum Level

Units of this type typically achieve vacuum levels up to 700-740 mmHg (absolute pressure), aligning with the stated 720mm.

Power Supply

Commonly requires a 3-phase electrical supply, typically 400V, 50Hz, as indicated by '3Ph'.

Operating speeds for these pumps are typically around 1450 RPM or 2900 RPM, depending on motor and application.

Cooling Medium

Requires a continuous supply of service liquid, typically water, for sealing and cooling.

• What are the main advantages of a liquid ring vacuum pump in food processing?

  Liquid ring pumps are well-suited for food processing due to their ability to handle condensable vapours and liquids, robust construction, and relatively low maintenance requirements. They also operate isothermally, which can be beneficial for heat-sensitive products.

• What maintenance is typically required for a liquid ring vacuum pump?

• Can this pump handle corrosive or abrasive food products?

• What kind of installation considerations are there for this type of pump?

• Is this unit suitable for continuous operation?

Vacuum pumps and systems are considered reliable workhorses in laboratory and pharmaceutical settings. Buyers typically value robust construction and consistent performance over extended service life. When purchasing used equipment, inspecting seals, gaskets and pump heads for wear is advisable, as these components determine longevity. Industry feedback suggests mechanical durability and energy efficiency as key strengths. Maintenance history and original manufacturer specifications prove important for ensuring compatibility with existing processes and regulatory compliance.
