Spare Parts and Accessories

The exact components inside a vacuum pump vary depending on its operating principle.

However, the main parts of most vacuum pumps include:

1. Inlet port: The pumped medium enters the vacuum pump via the inlet port.

2. Rotating component: At the center of the vacuum pump, there is a rotating component. This traps and compresses the pumped medium, before pushing it out, now at a higher pressure. The type of rotating component varies depending on the technology and may be, for example, a rotor, impeller, claw, or scroll.

3. Seals and gaskets: Seals and gaskets ensure that the vacuum pump is airtight and can create and maintain vacuum.

4. Lubrication system: Certain vacuum pump technologies require lubrication. Some rotary vane vacuum pumps, for example, work with oil lubrication. This reduces friction between the moving parts and the housing and creates a seal.

5. Motor or drive: The motor drives the vacuum pump.

6. Cooling system: Vacuum pumps generate heat during operation and require cooling systems to prevent overheating. They may be cooled with air, water, or another liquid according to the process.

7. Filters and separators: These important components prevent particles and liquids from entering or exiting areas they should not. This protects the vacuum pump and its surrounding environment and ensures that the pumped medium is not contaminated.

8. Outlet: Once the gas has been compressed to the required pressure, it exits the vacuum pump via the outlet.

You should always maintain your vacuum pump according to manufacturer specifications. These can be found in your vacuum pump’s instruction manual or in the specific service kit for your vacuum pump. Following these guidelines ensures proper care and performance.
To safeguard your warranty and ensure that your vacuum pump performs at its best, it’s crucial to exclusively use genuine spare parts during maintenance. By conducting regular inspections, oil changes, and filter replacements according to manufacturer recommendations, you will increase the lifetime of your vacuum pump and ensure it always performs at its best.

Certain vacuum pump components need to be replaced regularly. Vacuum pump oil, for example, degrades over time and loses its lubricating properties. It should therefore be changed regularly to maintain efficient operation. Filters and seals also need to be changed. A clogged filter or a leaking seal means that a vacuum pump needs to work harder, reducing its efficiency. And in a dry-running rotary vane vacuum pump, vanes wear down and must be replaced before they cause further damage or even vacuum pump failure. Proper maintenance of all these components ensures optimal performance and longevity. The recommended service intervals can be found in the instruction manual.

Yes, rebuilding or remanufacturing is an excellent way of extending the lifetime of your vacuum pump. However, this should only be done by Busch service technicians. To rebuild a vacuum pump, it is first completely disassembled. Then each component is examined individually and inspected. If any part is found to be worn or damaged, it is exchanged for a new one. Otherwise, it is cleaned, and the vacuum pump is reassembled and recalibrated, ready to be put back into service.

How long an industrial vacuum pump can last will vary depending on certain factors, such as the application in which it is used and how often maintenance is carried out. On average, well-maintained industrial vacuum pumps can last anywhere from 10 to 20 years, but with proper care, some can continue to operate efficiently for even longer. In fact, some vacuum pumps from Busch are still in service after over 30 years!

The cost of vacuum pump repairs can be extremely variable. It depends on what needs to be repaired, the extent of any damage, and whether your vacuum pump is still under warranty. Whether or not you have a service contract with Busch also plays a role: If you do, some or all repair costs may be covered. Our service technicians will give you a detailed and transparent quote that outlines all the necessary replacement parts and work that needs to be carried out. Contact us for an estimate.

For some maintenance, it is as simple as following the step-by-step instructions provided in your vacuum pump manual, or in the Busch genuine service kit. A service kit contains all the parts you need to carry out routine maintenance, such as changing the oil, filters, or vanes of your vacuum pump.
However, some more complicated repairs are best left to the professionals. Whichever parts need to be changed, the Busch field service will be happy to help you. Let us provide professional support and ensure your vacuum pump operates at its best.
