Eliminate process inefficiencies cause by vacuum.

The new VARODRY vacuum pump series is designed and produced by Leybold, in Germany specifically for industrial processes. Give yourselfone less headache, with VARODRY vacuum can be easy, efficient,reliable and dry.

“Our motivation was to develop the most energy efficient industrial dry pump!” 

Dirk Schiller, Head of engineering 


Efficient pumping

The VARODRY rotor design is optimized to provide best-in-class efficiency.

Pumping speed
The VARODRY provides a competitive pumping speed over the complete 
pressure range and a low end-pressure
of < 0.01 mbar. It can operate continuously at any inlet pressure.

Pump-down time (100 l chamber)
The VARODRY provides fast pump-down down to the 10-2 mbar range.

Power efficiency index
The effective pumping speed generated
per consumed power is a market benchmark for industrial dry pumps.

The VARODRY is optimized for the challenges found in many industrial applications:

Repeated and fast cycling
The VARODRY offers very quick pump down. The pump tolerates atmospheric pressure shocks and repeated evacuation cycles.

Dust / particle handling
The pumps screw principle offers best performance to handle fine, dry dust
particles without wear. A wide portfolio of dust filters are available if big dust amounts need to be handled.

Vapor handling
Due to its optimized temperature profile and the built-in gas-ballast, the VARODRY offers a high vapor tolerance, avoiding internal condensation and corrosion.

Reactive gas handling
Often vapors (e.g. hydrocarbons) tend to react inside hot dry pumps and build-up internal coatings which can cause pump seizing.The moderate temperatures inside the VARODRY virtually eliminate this risk.

Simple parts, less maintenance

Improve the efficiency of your machines. VARODRY makes it easy.

Operation costs
Being 100% air-cooled and dry, the VARODRY only consumes electricity, with no extra costs for cooling water supply or oil / oil-filter exchange and disposal. Its low power consumption will save significant operation costs.


Cost of Ownership Example: 
Composites
(wind power plant)

Compared with an oil-sealed rotary vane pump the VARODRY will save > 600 EUR operating costs per year!


“VARODRY – the easy, efficient, reliable
and dry solution for your processes!”

Uwe Zöllig, Business Development Manager Industrial Vacuum

User Maintenance
The belt can easily exchanged in less than 30 minutes. The exchange interval depends on the individual application but is typically >1 year. Belt-exchange kits and maintenance tool sets are available.

VARODRY reduces your maintenance
and service requirements
With only two wearing parts (belt and bearings), only minimal efforts are required to keep your pump running at peak performance – and improve the uptime at your facility.

Leybold Service
The bearings can be exchanged on site by trained Service technicians. Typical bearing lifetime is >3 years. Complete pump-overhauls can be done in one of the many Leybold Global Service hubs.

To ensure highest factory uptime, Leybold offers fastest “pump exchange”. Our back-up pools also offer flat rates for exchanging pumps, thus your production keeps running at all times.

Performance for your requirements.
