Mineral oil

Mineral oil

Mineral oil

Mineral oil is known for its exceptional compatibility with elastomers and resistance to hydrolysis. It is often referred to as semi-synthetic pump oil. Hydrocracked oils, on the other hand, are manufactured at high hydrogen pressures and elevated temperatures, making them largely free of aromatic compounds and olefins.

These oils offer several key benefits:

  • Enhanced thermal stability: They exhibit superior thermal stability when compared to traditional mineral vacuum pump oil.
  • Extended oil change intervals: In most cases, they allow for longer intervals between vacuum pump oil changes, contributing to cost savings and operational efficiency.
Synthetic oil – Ester

Synthetic oil – ester

Ester oil stands out as the preferred choice for vacuum pump applications that demand exceptional thermal performance.

Key properties of ester oil include:

  • High-temperature resilience: Ester oil is well-suited for operations at elevated temperatures, ensuring reliable performance even in demanding thermal conditions.
  • Moderate elastomer compatibility: It offers satisfactory compatibility with elastomers, striking a balance between effective sealing and functionality.

FAQ

Why does my vacuum pump require oil?

The oil inside the vacuum pump lubricates the pumping mechanism, while it collects moisture and contaminants from the evacuated systems. Simply put, oil is what keeps your pump pumping. 

What makes LEYBONOL better suited for my pump than other brands?

LEYBONOL oil is formulated from selected premium performance, highly refined raw materials, and processed without any contamination or dilution. With extensive quality controls, LEYBONOL oil is subjected to frequent ongoing and rigorous testing to ensure that each batch is consistent and provides the same outstanding vacuum performance. 

We design and test our oil under formal laboratory conditions but also in field conditions for all possible applications. 

How does vacuum pump oil contribute to lower cost of ownership?

High-quality vacuum pump oil, such as LEYBONOL, reduces power consumption, wear, and maintenance costs. In other words, LEYBONOL protects your pump and extends its life expectancy. LEYBONOL typically offers longer service intervals than other brands, so you save on maintenance costs.

Choosing high-quality oil both safeguards the reliable pump performance and lowers your total cost of ownership.

Can I use compressor oil in a vacuum pump?

Compressor oil and vacuum pump oil are not always compatible. Even though compressors and pumps sometimes share the same technology, like oil-sealed rotary screws or vanes, it’s not a good idea to mix or swap the lubricants. The properties of the oil, like viscosity and thermal oxidation stability, heavily depend on the application of the pump and, for example, the temperature. In some cases, it may work out fine, but our advice is to use the appropriate oil.

Use the oil finder to find out which oil is best for your pump.

How often should I change the oil in my vacuum pump?

Lubricants cannot be used indefinitely; as they age over time, their quality will degrade. Conditions like high temperatures, oxidation, or chemical and physical reactions with the process media can speed this aging even further. Not changing the oil in time can lead to the formation of sludges, resins, acids, and crystallization. An oil change is always part of a scheduled service.

How long the oil will last depends on the oil type. Synthetic oils with special additives are more resistant than mineral oils, for example. The standard lifetime of LEYBONOL’s oil is 0.5 years. Those oils offering extended lifetime should be changed after 1 year, and our “long lifetime” oils will last up to 2 years.

How does temperature affect oil quality?

Your pump oil durability depends on many parameters, such as temperature. Mineral oil has a maximum temperature limit of 80°C (176°F), above that the oil will thicken. We find that every 10°C temperature increase reduces the oil service life by half. Synthetic oil endures a permanent operation at 100-160°C (212-320°F). PFPE oil is almost inert, as it is not as subject to typical oil aging. Therefore, PFPE oil can stand permanent temperatures of up to 250°C (482°F). Operating conditions can also be too cold for the oil and as a result, water (and other) vapors may condense. Condensed liquid can cause loss of lubrication properties and even corrosion in the pump.

Can I mix various types of vacuum pump oils?

In some cases, oil are interchangeable, and, in some cases, it can cause serious damage. So we advise against this. Best case scenario your pump’s performance may deteriorate, worst case the whole pump may fail. In fact, the main cause of system problems is caused by mistakes with oil. Especially mixing two types of oil can cause issues and should be avoided. If you want to change over to PFPE oil, your pumps should be handled in one of our authorized service centers. The pump must be completely disassembled and cleaned. It will also have its filters and seals replaced and be regreased.

How do I dispose of used vacuum pump oil?

Never pour discarded vacuum pump oil down the drain. Collect the old oil in a suitable container, for example, the one it came in, and handle it according to local recycling regulations. You can refer to the Safety Data Sheet disposal considerations (normally in Section 13) for more information.

Does vacuum pump oil go bad?

The durability of your oil can deteriorate if you don't store it properly. Important recommendations for properly storing all LEYBONOL lubricants are:

1)      Storage temperature +10 to +30°C (+50 to +86°F)

2)      The containers should be protected against direct sunlight

3)      Drums should be stored horizontally

4)      Storage in enclosed indoor rooms

5)      The storage rooms should be clean and dry
