Intelligent, high performance Roots pumps for low and medium vacuum applications.

Intelligent and flexible
With their individual speed control, Roots pumps from the innovative HiLobe series can be adapted perfectly to customers’ specifications. Flexible installation positions allow the system size and installation costs to be reduced. The intelligent interface technology of the HiLobe enables optimal adjustment and condition monitoring of processes. This ensures a long service life and maximum operational reliability in your application.
Flexible control of the air cooling system enables individual temperature control of the HiLobe and thus ensures optimum adaptation of the pump temperature to your processes.

High performance
HiLobe pumps are available in a pumping speed range of 520 - 2,100 m3/h. Their superior drive concept permits extremely high differential pressures for a booster pump to be reached for short periods of time. This reduces pump-down times by around 20% compared to conventional Roots pumps.
In order to operate, Roots pumps require a suitable backing pump, adjusted to the gas flow, for the particular application.

Efficient
The integrated innovative and wear-free IE4 energy efficiency class motors and optimized rotor geometries make for low operating costs and high availability. The drive of the HiLobe line is hermetically sealed and has a maximum integral leakage rate of 1 - 10-6 Pa m3/s. This saves costs and time-consuming maintenance of shaft seals. In addition, it prevents any contamination of the process gas.
The use of sealing gas is unnecessary in most applications due to the sealing concept from the motor to the suction chamber.
