No other manufacturer offers the revolutionary performance of SIHI Boost UltraPLUS dry-running vacuum pumps:

Cut cycle times for batch processes by 50% or more

Significantly faster pump-down — 10 times faster than any other two-stage vacuum system
Potentially doubles the output of existing process equipment

Highest volume flows from atmospheric pressure to fine vacuum ranges

Delivers performance up to five times faster than traditional Roots-type blowers
Market-leading compression ratio (K0) of up to 100,000:1, which is exponentially higher than the rate of the highest-performing Roots-type blower (maximum 75:1)

Greater process control

Greater temperature control
Non-contacting spindle design enables the unit to operate at vacuum levels conventional Roots-type blowers can’t provide.

Use of liquid ring vacuum pumps as backing pump

Trouble-free pumping of sensitive media
High capacity for hydrogen

High suction capacity and fast pump-down, even with smaller backing pump

Lower total power consumption
Reduced costs for service/maintenance
Smaller footprint
Less backing pump capacity required

Completely oil-free operation

Electronic spindle synchronization ensures no-contact operation without a gearbox.
No process contamination from oil

Minimal maintenance and downtime

No rotating shaft or wearing seals
Fast in-situ service on-site
Condition monitoring replaces preventive maintenance

Low noise and vibration

Virtually silent operation
Getting rid of the gearbox also eliminates nearly all vibration.

No internal bypass required

Spindles can be exposed to atmospheric pressure, even when running at full speed.
