Busch R5 RA 0520 A – oil-lubricated rotary vane vacuum pump
The Busch R5 RA 0520 A is an oil-lubricated rotary vane vacuum pump. The nominal pumping speed is 430 m³/h (50 Hz) or 520 m³/h (60 Hz), the ultimate pressure 0.1 mbar. Nominal motor rating 11 kW (50 Hz) or 12.5 kW (60 Hz).Features
- Efficient: according to Busch up to 25 % more energy-efficient than comparable rotary vane pumps, high availability, lower heat emission
- Powerful: high pumping speed at low pressures, for continuous operation in rough vacuum, favourable ratio of performance to footprint
- Simple service: according to Busch 40 % fewer spare parts, all maintenance-relevant parts on one side, considerably faster maintenance, smooth surfaces for easy cleaning
