Busch R5 RA 0255D Vacuum Pump
The Busch R5 RA 0255D 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 0255D vacuum pumps and provide technical advice for replacement pump installations.
Where an exact Busch replacement is not essential, the higher-capacity DVP LC305 can provide a cost-effective upgrade, increasing nominal flow while retaining the same stated 7.5 kW motor rating at 50Hz.

Busch R5 RA 0255D Overview
The Busch R5 RA 0255D 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 250 m³/h at 50Hz.
The RA 0255D is commonly installed on high-output 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 0255D where the original pump specification needs to be retained.

DVP LC305
Higher-capacity 305 m³/h oil lubricated vacuum pump
Cost-Effective Capacity Upgrade
Upgrade to the DVP LC305
Where an exact Busch replacement is not essential, the DVP LC305 can provide a cost-effective capacity upgrade from the Busch R5 RA 0255D.
With a nominal capacity of 305 m³/h at 50Hz, 365 m³/h at 60Hz, a final pressure of 0.1 mbar absolute and a 7.5 / 8.6 kW motor rating, the LC305 provides approximately 22% more nominal capacity at both frequencies while retaining the same stated motor rating at 50Hz.
The DVP LC305 is designed for continuous industrial duty and combines improved oil-air separation with quieter operation, straightforward oil inspection and simplified routine maintenance.
Standard equipment includes an oil check valve, exhaust mist eliminator, automatic floating oil recovery valve, continuously working gas ballast, shock mounts, an oil filter with bypass and a flexible motor coupling.
An anti-suck-back arrangement helps prevent oil from being drawn into the connected system if the pump stops while operating under vacuum.
Vacuum Pumps UK is the UK and Ireland Master Agent for DVP Vacuum Technology.
Busch R5 RA 0255D and DVP LC305 Comparison
The comparison below shows the principal technical figures for each model. Final suitability should be checked against the machine, application and installation requirements.
| Specification | Busch R5 RA 0255D | DVP LC305 |
| Pump Technology | Single-stage oil lubricated rotary vane | Oil lubricated rotary vane |
| Nominal Capacity 50Hz | 250 m³/h | 305 m³/h |
| Nominal Capacity 60Hz | 300 m³/h | 365 m³/h |
| Ultimate Vacuum | 0.1 mbar absolute | 0.1 mbar absolute |
| Motor Power 50Hz | 7.5 kW | 7.5 kW |
| Motor Power 60Hz | 9.2 kW | 8.6 kW |
| Exhaust Oil Separation | Integrated separator elements | Exhaust mist eliminator and automatic oil recovery valve |
| Anti-Suck-Back Protection | Integrated non-return arrangement | Integrated anti-suck-back arrangement |
Important: The LC305 is a higher-capacity alternative rather than a dimensionally identical replacement. Mounting dimensions, inlet position, connection size, motor voltage, controls, required operating pressure and process conditions should always be checked.
Why Consider the DVP LC305?
Many customers searching for a Busch R5 RA 0255D require a dependable high-capacity oil lubricated vacuum pump rather than a specific manufacturer.
In these applications, the DVP LC305 provides increased pumping capacity, the same stated 7.5 kW motor rating at 50Hz, competitive pricing and direct technical support from the official DVP UK and Ireland Master Agent.
Higher Pumping Capacity
The LC305 provides 305 m³/h at 50Hz compared with 250 m³/h from the Busch RA 0255D.
Efficient Motor Selection
Both pumps use a stated 7.5 kW motor at 50Hz, while the LC305 is listed at 8.6 kW at 60Hz compared with 9.2 kW for the Busch pump.
Cost-Effective Alternative
The LC305 may provide a more economical higher-capacity option where the application does not specifically require the Busch model.
