Key features
Why the Root Vacuum Pump
- High pumping speed — suitable for large gas volumes.
- Oil-free pumping chamber — no oil enters the compression space.
- Non-contacting rotors — minimizes wear inside the pumping chamber.
- High reliability — suitable for continuous industrial operation.
- Low maintenance — mainly requires attention to bearings, seals and timing-gear lubrication.
- Wide capacity range — can be designed from small laboratory units to very large industrial boosters.
- High-temperature capability — suitable designs can handle elevated gas temperatures.
- Low contamination — useful for clean vacuum processes.
- Vertical or horizontal installation — depending on the pump design.
- Can operate with a backing pump — commonly used in combination with dry screw, rotary vane, liquid-ring or other backing pumps.
- Bypass/relief protection — commonly provided to prevent excessive differential pressure.
- Air- or water-cooled versions — depending on pump size and application.
