R5

R5 RA oil-lubricated rotary vane vacuum pumps are real all-rounders. They have been designed for a wide range of industrial applications, for example vacuum packaging, food processing, pneumatic conveying, plastics processing and many more.

These vacuum pumps are characterized by high pumping speeds even in low pressure ranges and therefore rapid evacuation times.

They feature highly durable high performance vanes as standard, ensuring excellent performance and a long service life.

R5 RA vacuum pumps are designed for continuous operation. An integrated float valve regulates the oil return depending on the oil level.

Vacuum pumps of the RA series are ultimate pressure-proofed. They can be operated continuously at ultimate pressure without overheating.

The fully connected Busch R5 PLUS series vacuum pumps bring the proven Busch rotary vane vacuum technology to the next level.

PLUS technology combines proven Busch experience with cutting-edge features for Industry 4.0. Everything you need in one unit.

R5 RD rotary vane vacuum pumps are the new standard for vacuum packaging. They are also well-established in a variety of other industrial applications.

High efficiency is the outstanding quality of this series. With an up to 30% lower energy consumption compared to conventional rotary vane vacuum pumps.

Heat emission has also been reduced thanks to an improved cooling air flow. Together with an optimized heat discharge, this contributes to a low ambient temperature.

All service relevant components are mounted on one side of the vacuum pump for easier access. Therefore, the service routine becomes significantly faster. And the smooth surface design facilitates cleaning.

The single exhaust filter can be replaced in less than a minute. Moreover, it provides enhanced filtration performance for best-in-class oil separation.

R5 RD vacuum pumps feature hard-wearing carbon fiber vanes as standard, ensuring excellent performance and a long service life.

R5 KB rotary vane vacuum pumps are characterized by their compact construction, light weight and high performance.

They are perfectly suited for installation in confined spaces, for example in vacuum packaging machines. The integrated motor and transmission make them the ideal choice for fixed installations.

R5 KB feature highly durable Busch fiber-reinforced epoxy resin vanes as standard. This ensures an optimum performance and long service life.

R5 KD rotary vane vacuum pumps are characterized by their compact, light-weight construction and high performance. This makes them the perfect choice for table top packaging machines in butcheries, restaurants, canteens or supermarkets.

In table top packaging applications, a small number of packaging cycles and short operating times of the vacuum packaging machines are common. However, this can lead to moisture accumulation and corrosion inside the vacuum pump. This is exactly what the R5 KD series has been optimized for. Improved moisture tolerance and effective corrosion protection make them ideal for these operating conditions. And therefore for the packaging of humid products suchs as meat or fish.

R5 KD series vacuum pumps are equipped with a newly developed exhaust filter for faster replacement and easier maintenance. They feature an improved temperature management without any cooling fins. This ensures a smooth surface design, which makes the R5 KD easy to clean.

R5 PB rotary vane vacuum pumps are the smallest vacuum pumps of the R5 series. Their block construction with directly mounted motor permits installation in confined spaces, like table-top packaging machines. Moreover, they are characterized by their quiet operation.

This makes them the perfect choice for food applications in deli counters or restaurants. For example, for sous-vide cooking or marinating and preserving foodstuffs.

R5 PB series vacuum pumps feature highly durable rotor vanes as standard. This ensures a long service life and makes them nearly maintenance-free. A thermo-protecting element prevents the motor from overloading.

R5 RE are explosion pressure resistant rotary vane vacuum pumps. They have been specially designed to extract explosion-endangered gas/air and vapor/air mixtures.

These vacuum pumps are certified in accordance with directive 2014/34/EU for II 1G h IIB3 T4 Ga inside and II 2G h IIB3 T4 Gb outside the vacuum pump.

Their ATEX certification makes them suitable for the extraction of almost all materials in the IIB3 explosion group. They can also be used for the extraction of petrol vapor.

R5 RE series vacuum pumps are driven by a directly flange-mounted explosion-proofed electric motor. They come with flame arresters as standard.

RB/RC rotary vane vacuum pumps are characterized by their compact construction. This makes them ideal for installation in confined spaces. For example, in packaging machines.

The R5 RB has been designed for cyclical operation. The R5 RC is equipped with a sophisticated oil return line for continuous operation.

R5 RB/RC feature highly durable Busch fiber-reinforced epoxy resin vanes as standard. This ensures an optimum performance and long service life.

With the invention of the R5 oil-lubricated rotary vane vacuum pump, Dr Karl Busch has revolutionized food packaging. And today, we are the market leader in vacuum packaging.

However, the R5 is not limited to this application but represents the industry standard for a wide range of applications. Every day, over 3 million R5 vacuum pumps are in operation around the globe. In the course of over 50 years, we have continuously developed and optimized rotary vane technology. Always with a strong focus on energy efficiency.

Throughout the industry, the R5 is known for its robustness and reliability. You can always rely on the R5 – whether used intermittently or around the clock.

A wide range of sizes, design options and accessories ensures that the R5 is the perfect match for many processes.

Maintenance can easily be carried out by the operator. Apart from changing oil and filters at regular service intervals, no further maintenance is required.

The R5 vacuum pumps from Busch are oil-lubricated rotary vane vacuum pumps. They utilize oil to help seal the clearance between the vanes and the housing. This ensures smooth operation and longevity of the vacuum pump components. R5 vacuum pumps are moreover fitted with an oil mist separator, consisting of an oil filter and an exhaust filter. The oil filter removes contaminants, such as dust and debris, from the oil, ensuring that it remains clean and retains excellent lubrication and sealing properties.The exhaust filter captures oil particles in the discharged gas, ensuring that oil emissions to the ambient air are reduced to an absolute minimum.

All of these vacuum pumps operate with rotary vane technology. The main differences lie in the number of compression stages and the type of lubrication. Single-stage pumps, such as the R5 and SECO, compress the medium once. Two-stage pumps, like the HUCKEPACK, compress it twice, which allows them to reach higher vacuum levels. The R5 and HUCKEPACK are oil-lubricated. In the R5, the oil is collected and continuously recirculated for reuse, while in the HUCKEPACK, the oil passes through the vacuum pump only once before being discharged. The SECO, on the other hand, is dry-running. It uses graphite vanes that generate fine dust for lubrication as they glide along the cylinder wall.
