  • Small- and medium-sized two-stage rotary vane pumps where high ultimate vacuum and good lubrication are required
  • Gearboxes and drive trains under vacuum or partial pressure. Large single stage rotary vane pumps requiring a heavier grade oil to create a vacuum seal
  • Large capacity two-stage rotary vane pumps, especially when used under high load or fast duty cycles.

Mineral vacuum pump oil for food processing applications

The Ultragrade® Performance Pure range are H2-specific vacuum lubricants used in food processing applications. This foodgrade mineral oil is typically used by rotary vane pups of all sizes and capacities.

Chemically stable and resistant to acids, alkalis, halogens, and oxides of nitrogen. Ideal in applications where silicones cannot be tolerated.

This fluid has low viscosity which permits easy filling and draining. Intended for high vacuum industrial applications where silicones cannot be tolerated.

This oil’s molecular structure offers chemical inertness, high-temperature stability, and low vapour pressure. Specifically suitable for EH boosters.

Heavily distilled with unsaturated and aromatic links removed and no additives. This long-lasting lubricant is developed for applications where rotary pump oils are likely to be exposed to reactive or corrosive substances.

We offer various silicone oils that are highly resistant to chemicals, oxidation, radiation and thermal stress. These types of oil are suited for diffusion pumps, applications in vacuum coating and other processes where ultra-clean and ultra-high vacuum is required.

Corrosive resistant properties and chemical inertness PFPE. Used in applications where hostile process conditions quickly destroy normal hydrocarbon pump oil.


Common questions about vacuum pump oil

Explore the answers to some of the most popular questions other customers have had. Didn’t find your question in the list? Then just reach out to the local expert in your region by filling out the form below. 

What is vacuum pump oil?

Vacuum pump oil is a specialized type of lubricant used in vacuum pumps to provide lubrication, to seal vacuum systems, and to maintain the performance of the pump.

Vacuum pumps are used to create a vacuum or negative pressure by removing gas molecules from an enclosed space. Vacuum pump oil is required in these pumps to provide lubrication to the moving parts, such as rotors or vanes, and to create a seal between the moving parts and the pump housing. This seal is critical to maintain the vacuum pressure and prevent the leakage of air or other gases into the system.

Why is vacuum pump oil important?

Proper lubrication with high-quality vacuum pump oil is important for ensuring the efficient and reliable operation of vacuum pumps. It can also help to prevent damage to pump components and reduce maintenance costs.

What are the different types of vacuum pump oil?

There are several different types of vacuum pump oil available, including mineral oil, synthetic oil, and specialty blends. The specific type of oil needed depends on the type of pump and the application. Use the Edwards oil finder to find the right oil for your equipment.

How do I choose the right vacuum pump oil?

When selecting vacuum pump oil, consider factors such as viscosity, compatibility with the pump material, and the specific requirements of the application. Use the Edwards oil finder to find the right oil for your equipment or contact your service representative.

How often should I change my vacuum pump oil?

The frequency of oil changes depends on the specific pump and application. In general, vacuum pump oil should be changed every three to six months, or more frequently for high-use applications or when the oil appears dirty or contaminated. Always consult the service manual of your pump.

How do I change my vacuum pump oil?

To change vacuum pump oil, first drain the old oil and dispose of it properly. Every pump comes with a service manual that explains exactly how you can change and dispose of the oil.
Refill the pump with the recommended amount and type of oil, and run the pump for several minutes to distribute the oil throughout the system.

What are some common problems with vacuum pump oil?

A: Common problems with vacuum pump oil include contamination, oxidation, and thermal breakdown. These issues can cause decreased pump performance, increased maintenance requirements, and premature pump failure. You can avoid these issues by selecting the right type of oil for your pump and conducting regular maintenance.

How do I dispose of used vacuum pump oil?

A: Used vacuum pump oil must be disposed of properly, in accordance with local regulations. Contact a waste management company or environmental agency for guidance on proper disposal methods.

Can vacuum pump oil be recycled?

Yes, vacuum pump oil can be recycled, but it requires specialised equipment and processes to remove contaminants and restore the oil's performance properties.

Used vacuum pump oil can become contaminated with debris, moisture, and chemical impurities that can degrade its performance and increase the risk of equipment failure. Recycling vacuum pump oil involves removing these contaminants through a combination of filtration, distillation, and chemical treatment processes.

Vacuum pump oil recycling is typically done by specialised oil recycling companies, who use equipment and processes to separate the oil from contaminants and restore its properties. This process can help extend the life of the oil and reduce waste and environmental impact by reducing the need for disposal of used oil.

Not all vacuum pump oils can be recycled, and the suitability for recycling will depend on the specific formulation and condition of the used oil. Therefore, it is important to consult with a qualified oil recycling company to determine the best course of action for disposing of used vacuum pump oil.

What’s the difference between compressor oil, hydraulic oil and vacuum pump oil?

Compressor oil, hydraulic oil and vacuum pump oil are three different types of lubricants used in different types of machinery.

Compressor oil is designed to resist oxidation, maintain viscosity under high temperatures, and provide excellent lubrication under high pressure. It typically contains additives to prevent rust and corrosion in the compressor system.

Hydraulic oil is designed to provide lubrication, resist oxidation, and maintain stable viscosity across a range of temperatures. It also contains additives to prevent rust, corrosion, and foaming.

Vacuum pump oil, on the other hand is designed to withstand the harsh operating conditions of a vacuum pump, including high temperatures and pressures, and resist degradation from chemical exposure. It is typically formulated with low vapour pressure to minimise contamination of the vacuum system and maintain a high level of vacuum performance.

While compressor oil, hydraulic and vacuum pump oil are all designed to provide lubrication to machinery, they are formulated to meet different requirements and should not be used interchangeably. Using the wrong type of oil in your vacuum pump can lead to decreased performance, increased maintenance requirements, and premature equipment failure.

Can I use mineral oil in a vacuum pump?

This depends on the specific vacuum pump and its requirements. Mineral oil is a type of vacuum pump oil that is commonly used in many types of vacuum pumps, particularly those with lower performance requirements or for pumps that are operated intermittently.

However, some vacuum pumps require specialised oil formulations, such as synthetic or specialty blends, to meet specific operating conditions and performance requirements. Using the wrong type of oil in a vacuum pump can lead to decreased performance, increased maintenance requirements, and premature equipment failure. Always consult the instruction manual of your vacuum pump, or use our oil finder to find the right type of oil for your equipment.
