Use Labovac pump oils with Welch pumps to reduce oil change cycles and maximise performance. This warranty is only effective when using Welch qualified vacuum pump oils.
Labovac 10 - Mineral oil:
• Standard oil for one and two-stage Welch rotary vane pumps and chemvac's.
• Can be used too pump air, inert gas and noble gas.
• Oil service cycles can be extended by using an oil filter.
Labovac 11- Synthetic oil:
• Used for high operating temperatures >100 °C, specially in one-stage rough vacuum rotary vane pumps.
• Do not pump any inorganic acids
• Ultimate pressure up to 0,5 mbar.
Labovac 12S - Paraffin based mineral oil:
• For pumping air, chemically inert permanent gases - water vapour, solvent vapours.
• Oil service cycles can be extended by using a chemical oil-filter.
• Pump should operated with a cold trap.
Labovac 13- PFPE oil:
• For pumping strong oxidants like oxygen, ozone and reactive substances (halogens).
• Mixing with other types of oil must be absolutely avoided
• Recommend to order the rotary vane pump directly with these vacuuum oil to ensure best performance.
Labovac 14- Polyalphaolefin oil (PAO):
• For pumping of chemically inert permanent gases - water vapour and solvent vapours. Improved cold starting at low temperatures.
• A oil-filter is strongly recommend.
• Ultimate pressure up to 10⁻² mbar.
