Busch R5 RA 0400C Vacuum Pump
The Busch R5 RA 0400C is a high-capacity single-stage oil lubricated rotary vane vacuum pump designed for continuous industrial duty across packaging, food processing, production machinery and centralised vacuum systems.
Vacuum Pumps UK can supply new Busch R5 RA 0400C vacuum pumps and provide technical advice for replacement pump installations.
Where an exact Busch replacement is not essential, we can offer a suitable alternative pump, or assess the DVP LX550 as a higher-capacity single-pump alternative or the DVP XC405 as a modular duplex vacuum pump system.

Busch R5 RA 0400C Overview
The Busch R5 RA 0400C is part of the established Busch R5 range of oil lubricated rotary vane vacuum pumps.
It is a single-stage pump developed for continuous-duty industrial applications requiring high pumping speed at low operating pressures and a nominal capacity of 400 m³/h at 50Hz.
The RA 0400C is commonly installed on large packaging lines, tray sealing and thermoforming equipment, food processing systems, plastics machinery, vacuum conveying equipment and centralised vacuum installations where production uptime is critical.
Oil within the pump lubricates the working components, assists sealing and supports stable operating temperature. Integrated exhaust separation helps recover oil within the pump and reduce oil mist from the exhaust.
Vacuum Pumps UK can assist with the supply of a new Busch R5 RA 0400C where the original pump specification needs to be retained.

Busch R5 RA 0400C Pump Features
Oil Lubricated Rotary Vane
Oil provides lubrication and sealing within the pumping chamber while supporting stable vacuum performance.
High-Capacity Performance
A nominal capacity of 400 m³/h at 50Hz supports larger machinery and demanding industrial vacuum duties.
Integrated Inlet Protection
The intake filter helps prevent larger particles from entering the vacuum pump.
Oil Mist Separation
Integrated exhaust separator elements help retain oil within the pump and minimise oil mist emissions.
Non-Return Protection
An integrated non-return arrangement helps prevent unwanted reverse flow when the pump stops.
Continuous Industrial Duty
The RA 0400C is designed for demanding production environments where dependable continuous vacuum is required.

DVP Replacement Options
Consider the DVP LX550 or XC405
Where an exact Busch replacement is not essential, the most suitable DVP solution depends on whether the application is better served by one larger-capacity pump or a modular two-pump system.

DVP LX550
Higher-capacity single-pump alternative
With a nominal capacity of 550 m³/h at 50Hz and 600 m³/h at 60Hz, the LX550 provides a substantial capacity increase over the Busch R5 RA 0400C.
The LX550 has a stated total final pressure of 0.5 mbar absolute and a motor rating of 15 / 18 kW. It is designed for high-capacity continuous service and is equipped with automatic lubrication, air cooling, an oil check valve, continuous gas ballast and shock mounts.
This option is suitable where additional pumping capacity and a reduction on evacuation time is valuable.

DVP XC405 Duplex System
Closely matched modular two-pump solution
The XC405 combines two DVP LC205 oil lubricated rotary vane pumps to provide a nominal system capacity of 410 m³/h and a stated total final pressure of 0.5 mbar absolute.
Each pump has a 5.5 kW motor, giving a total installed motor rating of 2 × 5.5 kW. The modular arrangement allows one or both pumps to be used according to the required flow, helping reduce unnecessary energy use when full capacity is not needed.
The duplex arrangement also allows maintenance to be carried out on one pump while the other remains available, although the remaining capacity must be sufficient for the process.
Vacuum Pumps UK is the UK and Ireland Master Agent for DVP Vacuum Technology.
Busch R5 RA 0400C, DVP LX550 and XC405 Comparison
The comparison below shows the principal technical figures for the Busch pump and the two DVP options. Final suitability should be checked against the machine, operating pressure, duty and installation requirements.
| Specification | Busch R5 RA 0400C | DVP LX550 | DVP XC405 |
| Configuration | Single oil lubricated rotary vane pump | Single oil lubricated rotary vane pump | Duplex system with 2 × LC205 pumps |
| Nominal Capacity 50Hz | 400 m³/h | 550 m³/h | 410 m³/h |
| Nominal Capacity 60Hz | 480 m³/h | 600 m³/h | 410 m³/h |
| Ultimate / Final Pressure | 0.1 mbar absolute | 0.5 mbar absolute | 0.5 mbar absolute |
| Motor Power 50Hz | 11.0 kW | 15.0 kW | 2 × 5.5 kW |
| Motor Power 60Hz | 15.0 kW | 18.0 kW | 2 × 5.5 kW |
| Operating Flexibility | Single fixed pump | Single fixed pump with higher capacity | One or both pumps can be operated |
| Maintenance Continuity | Pump unavailable during maintenance | Pump unavailable during maintenance | One pump may remain available at reduced capacity |
Important: Neither DVP option should be treated as a dimensionally identical replacement. Mounting dimensions, inlet position, connection size, motor voltage, controls, actual operating pressure and process conditions should always be checked.
Why Consider the DVP LX550 or XC405?
Many customers searching for a Busch R5 RA 0400C require dependable high-capacity vacuum performance rather than a specific manufacturer.
The DVP alternatives provide two different routes: the LX550 offers increased capacity from one pump, while the XC405 provides a closely matched total flow from two smaller pumps with modular operation and maintenance flexibility.
Higher-Capacity Single Pump
The LX550 provides 550 m³/h at 50Hz where additional pumping capacity is required.
Closely Matched Duplex Flow
The XC405 provides 410 m³/h from two LC205 pumps, closely matching the Busch pump’s 400 m³/h at 50Hz.
Modular Operation
The XC405 can operate one or both pumps according to the required vacuum flow, helping avoid unnecessary full-capacity operation.
