Busch - Busch RA0255 Vacuum pumps

Applications & Use Cases

• Vacuum packaging of food products to extend shelf life.
• Degassing and de-aeration in food processing, such as for sauces or confectionery.
• Vacuum conveying of powders and granular materials in food production lines.
• Operating vacuum fillers and depositors for viscous food products.
• Forming and thermoforming applications for food packaging.

Typical Specifications

Typical vacuum level

For this class of Busch RA series pumps, ultimate vacuum typically ranges from 0.1 to 0.5 mbar (absolute).

Nominal pumping speed

The RA0255 model typically offers a nominal pumping speed of around 250-300 m³/hr at 50 Hz.

Power supply

Units of this type commonly require a 3-phase electrical supply, typically 400V, 50Hz.

Motor power

For a pump with this pumping speed, the motor power is typically in the range of 5.5 to 7.5 kW.

Cooling method

Busch RA series pumps are typically air-cooled, simplifying installation requirements.

Oil type

These are oil-lubricated rotary vane pumps, requiring specific vacuum pump oil for operation and maintenance.

Footprint

A unit like the RA0255 typically has a compact footprint, suitable for integration into existing production lines.

Frequently Asked Questions

• What is the difference between the RA0255, WV0500, and RA0250 models?

  The RA models (RA0255, RA0250) are typically oil-lubricated rotary vane vacuum pumps, primarily designed for ultimate vacuum. The WV0500 is likely a Roots booster pump, used in conjunction with a backing pump (like an RA model) to achieve higher pumping speeds at lower pressures.
