Busch Vacuum Pump Model 400-212

• Vacuum packaging of various food products to extend shelf life.
• Modified atmosphere packaging (MAP) systems in food processing.
• General industrial vacuum applications requiring high flow rates.
• Degassing processes in food and other industries.

Typical capacity

Units in this class, such as the Busch 400-212, commonly offer free air displacement around 235 CFM (cubic feet per minute) or approximately 400 m³/hr.

Power supply

Industrial vacuum pumps of this size typically require a 3-phase electrical supply, commonly 400V or 415V, 50Hz in the UK.

Vacuum level

For this class of rotary vane vacuum pump, an ultimate vacuum of around 0.5 mbar (absolute) is commonly achievable.

Footprint

Industrial vacuum pumps of this capacity typically have a substantial footprint, requiring dedicated floor space within a processing facility.

Cooling

These units are generally air-cooled, but some larger models or specific applications may feature water cooling.

Maintenance

Routine maintenance typically involves oil changes, filter replacements, and checking drive belts, with intervals depending on usage.

• What is the primary benefit of a vacuum pump like this in food processing?

  The primary benefit is the removal of air from packaging, which significantly extends the shelf life of perishable food products by inhibiting microbial growth and oxidation.

• Can this pump be used for continuous operation?

• What type of oil does this vacuum pump typically use?

• Is this unit suitable for wet or humid applications?

• What are the common wear parts that might need replacement?

Vacuum packaging equipment holds a solid reputation in food processing for extending shelf life and maintaining product quality. Buyers typically prioritize seal consistency, chamber durability, and ease of operation when selecting used models. Industry sentiment favours machines with reliable vacuum pump performance and straightforward maintenance access. Common strengths include cost savings over new equipment, proven track records from established manufacturers, and compatibility with various packaging materials. Prospective buyers should inspect sealing bars, vacuum gauges, and prior service history carefully.
