Description
Vacuum Pump Oil VM4 is a high-performance, mineralbased lubricant specially formulated for rotary vane and dryseal vacuum pumps operating in lighttomedium vacuum ranges. Its ultralow vapor pressure and superior thermal stability ensure consistent, efficient vacuum levels while minimizing carryover and carbon deposits. With exceptional antifoam properties and oxidation resistance, VM4 extends oil drain intervals and protects pump components under continuous or cyclic duty. Ideal for critical applications where contamination control and oil longevity are paramount.
Key Features
- UltraLow Vapor Pressure: Minimizes oil vapor carryover for cleaner vacuum systems.
- High Thermal & Oxidation Stability: Resists breakdown at elevated temperatures, reducing sludge formation.
- Excellent Demulsibility: Separates quickly from water, protecting pump internals in humid environments.
- AntiFoam & AirRelease: Prevents foaming and entrainment, ensuring smooth, uninterrupted pump operation.
- Wide Operating Range: Performs reliably from 10C to 200C, covering most industrial vacuum needs.
Applications
- Laboratory vacuum systems (freeze drying, distillation, filtration)
- Packaging machinery (vacuum sealing, thermoforming)
- Medical & pharmaceutical equipment
- Semiconductor manufacturing
- Food processing & dehydration
- Power plant condenser evacuation
