Busch R5 RA 0302D Vacuum Pump
The Busch R5 RA 0302D is one of the older R5 rotary vane models commonly found on packaging, printing, plastics and general manufacturing equipment.
Busch has moved on to later R5 generations, so this model is now an earlier production design rather than a current catalogue pump. Many examples remain in productive service, making spare parts, oil separator replacement, maintenance and workshop repair an important part of ongoing support.
A replacement does not always need to be another Busch pump. The DVP LC305 is a competitively priced alternative supported by Vacuum Pumps UK from UK stock, helping reduce both initial pump cost and lead time on many installations.

Busch R5 RA 0302D Overview
The Busch R5 RA 0302D is an oil lubricated rotary vane vacuum pump rated at 300 / 360 m³/h at 50Hz / 60Hz, with a stated maximum vacuum of 0.1 mbar absolute.
It is typical of the earlier Busch R5 generation: mechanically robust, widely installed and capable of a long working life when oil, filters and oil separator elements are maintained correctly. These pumps are still found on food and non-food packaging lines, plastics processing equipment, vacuum handling and factory automation.
The installed population remains significant, which makes parts and repair support commercially important. At the same time, older units are increasingly reaching the point where replacement can be more economical than repeated repair.
Vacuum Pumps UK can help decide whether to continue maintaining the existing Busch R5 RA 0302D, overhaul it, source a certified refurbished pump where available, or move to a current DVP alternative.
Busch R5 RA 0302D Technical Specifications
These figures provide a useful reference when identifying an existing pump or considering a replacement. Always check the actual nameplate, motor supply, inlet connection, exhaust arrangement and operating duty before ordering.

Older Busch R5 Pumps Still in Service
The Busch R5 RA 0302D may be from a previous production generation, but that does not make the installed pumps obsolete overnight. Industrial vacuum pumps often remain on machinery for many years, particularly where the application is stable and maintenance has been carried out correctly.
For that reason, we continue to treat the older R5 population as an active service market. Routine separator and oil changes can keep a healthy pump running efficiently, while a worn pump can often be rebuilt. Where repair cost becomes disproportionate to the remaining condition of the unit, replacement with a modern pump becomes more attractive.
This is particularly relevant to older pumps: after years of operation the motor, bearings, cylinder, rotor, vanes, valves and oil system may all have accumulated wear. A replacement decision should consider the whole pump, not just the immediate failed component.
Typical Applications
The Busch R5 RA 0302D has been used across a broad range of industrial equipment. Typical duties include food and non-food packaging lines, plastics processing equipment, vacuum handling and factory automation. Actual suitability depends on the required operating vacuum, gas load, contamination level and duty cycle.
DVP LC305
Cost-effective replacement option
Comparable DVP Alternative
Consider the DVP LC305
Where retaining the exact Busch model is not necessary, the DVP LC305 can be considered as a modern oil lubricated rotary vane alternative. DVP pumps are manufactured in Italy and supplied in the UK by Vacuum Pumps UK as the UK and Ireland Master Agent.
Cost and availability are important advantages. The DVP range can offer a lower initial purchase price than an equivalent premium-brand replacement, while UK-held stock can significantly reduce waiting time where the required model is available.
The LC305 closely follows the 300 m³/h duty point and is the most natural DVP model to assess for replacement.
A model comparison is only the starting point. Mounting dimensions, inlet and exhaust positions, connection sizes, motor voltage, electrical controls, operating pressure, process conditions and available space should all be checked before changing pump.
Vacuum Pumps UK can assess the application and confirm whether the DVP LC305 is suitable before supply.
Busch R5 RA 0302D vs DVP LC305
The table gives a quick performance comparison. The DVP pump should not be treated as a dimensional drop-in until the installation has been checked.
| Model | Capacity 50Hz / 60Hz | Ultimate / Maximum Vacuum | Motor 50Hz / 60Hz |
| Busch R5 RA 0302D | 300 / 360 m³/h | 0.1 mbar abs. | 5.5 / 7.5 kW |
| DVP LC305 | 305 / 365 m³/h | 0.1 mbar abs. | 7.5 / 8.6 kW |
Busch R5 RA 0302D Spare Parts, Oil Separators, Oil, Service & Repair
Because the Busch R5 RA 0302D is an older but still commonly installed pump, aftermarket support is a major part of our offering. Through our sister company VacAir Superstore we can support planned maintenance, breakdown repair and overhaul work for Busch R5 oil lubricated vacuum pumps.
Spare Parts
Service kits, filters, gaskets, seals, valves and mechanical components can keep an otherwise serviceable R5 pump operating reliably.
Oil Separators
Exhaust separator elements are critical to oil recovery and exhaust quality. Saturated or damaged separators can cause oil mist, increased back pressure and poor running.
Vacuum Pump Oil
Correct vacuum pump oil supports lubrication, sealing, cooling and vacuum performance. Oil condition should be checked especially closely on older pumps and contaminated applications.
Service & Maintenance
Planned servicing can include oil and separator changes, filter replacement, leak checks, operating-temperature checks and assessment of noise, vacuum and oil carry-over.
Repair & Overhaul
Our workshop can investigate worn or failed Busch pumps and advise whether repair, overhaul, a certified refurbished unit or replacement offers the best value.
For older R5 pumps, the right answer is not automatically repair or replacement. We can help compare both routes against the age, condition, duty and cost of the existing pump.
Busch R5 RA 0302D Frequently Asked Questions
Is the Busch R5 RA 0302D still a current-production model?
No. It belongs to a previous generation of Busch R5 oil lubricated rotary vane pumps. Many units remain in service, however, and can still be supported with maintenance parts and repair expertise.
Can you still supply parts and oil separators?
Yes. VacAir Superstore supports older Busch R5 pumps with spare parts, oil separator elements, vacuum pump oil and service components.
Is it worth repairing an older Busch R5 RA 0302D?
Often it is, particularly where the major mechanical components remain in good condition. If the pump has extensive internal wear or several expensive components require replacement, a modern replacement may offer better value.
What DVP pump can replace the Busch R5 RA 0302D?
The DVP LC305 is the primary alternative considered on this page. The LC305 closely follows the 300 m³/h duty point and is the most natural DVP model to assess for replacement.
Why consider a DVP replacement?
DVP offers European-manufactured oil lubricated rotary vane pumps at competitive initial purchase prices, with UK stock support through Vacuum Pumps UK. This can make them attractive where an older Busch pump has reached the point that replacement is more economical than overhaul.
Can I replace the Busch pump based on m³/h alone?
No. Pumping speed is only one part of selection. Required vacuum, dimensions, pipe connections, motor power, voltage, controls, process contamination and duty cycle must also be checked.
