Premium Vacuum Pump Oil, 1 Litre, 1000ml

Product Information

Long service life due to high level of chemical and thermal stability and freedom from deposit formation Fisher Scientific vacuum pumps combine high tech materials with outstanding engineering. They are designed for most laboratory applications, both routine and research. When choosing a vacuum pump, consider your application type, sample composition and operating parameters. Yes, vacuum pump oil can be recycled, but it requires specialised equipment and processes to remove contaminants and restore the oil's performance properties. Bryan Orr hosted a live podcast discussion all about 90% efficient furnaces with HVAC professionals Ty Branaman, Adam Mufich, and Matthew Bruner. They covered the basics of how 90% furnaces work compared to traditional 80% furnaces, troubleshooting tips, and best practices for installation and service. Oil” is a bit of a misnomer because modern pump oil technology has evolved well beyond the original distilled petroleum products.

This is best tested with a high vacuum gauge mounted directly on the inlet port.

Typical Properties

There are now double- and triple-distilled oils available, as well as hydro-treated oils, low sulfur oils, silicone-based synthetic oils, and flushing oils used to clean the pump. Due to the wide variety of formulations available, these are often now referred to as pump “fluids” rather than pump “oils.” Mobil Vacuum Pump Oil 100 has a high degree of chemical stability enabling it to resist oxidation and the subsequent formation of sludge and deposits, an essential characteristic in all cases where continuous service in involved. This enables the oil to retain its original properties such as viscosity and demulsibility and so prolong oil service life.

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. Also consider whether an oil-free or diaphragm pump would be better for applications involving low volumes, degassing, gas transfer and sampling, or else a lubricated pump for high capacity, high vacuum performance.Provides a seal across the vanes and duo seal between the high pressure and low-pressure side of the pump in two-stage pumps

A seal in a vacuum pump between its high pressure and low pressure, or induction and exhaust sections of the pumping process, specifically for rotary vane pump application, allows for separation of gas and oil within the pump, reducing unwanted contamination. If you look at the video above, the seal needs to be created at the top of the rotor and in between the vanes and the chamber. Triple-distilled oil goes through yet another molecular distillation process and is devoid of sulfur or other impurities. This oil is chemically inert and is highly resistant to oxidation and reactance to other gases. Triple-distilled pump oil is transparent and is designed for an ultimate vacuum of 0.6 microns (6 x 10 -4 torr). In practice, techs are often taught to leave the ballast open until the pump can pull the system below a pressure (measured with a vacuum gauge at the system) below the boiling pressure of water for the ambient temperature. Then, you would close the ballast to pull the final deep vacuum. Vacuum Expert Howard Tring noted that leaving the ballast open until you get to the boiling point of water is a waste. The goal is to leave the ballast open only when it is stalled at the moisture evaporation pressure/temperature point. These application-specific oils need to be refined for vacuum pump application and must be pure from additives, except for anti-foaming, anti-oxidation, or corrosion-resistant additives.When the vacuum pump is not reaching the desired vacuum level. This is best tested with a vacuum gauge placed directly on the pump. Most HVAC application vacuum pumps are rotary vane pumps in a single- or double-stage design. A vacuum pump moves vapor molecules out of the system, working in and out of the pump through the vacuum pump oil itself. That process makes the vacuum pump oil one of the most critical variables in the evacuation process. As soon as there is a notable difference from its original clear state is a good time to change your oil. The signs above of contaminated vacuum pump oil help you determine whether your vacuum pump oil has altered its ability to keep its designed viscosity or its vapor pressure for maximum efficiency.
