Pfeiffer Vacuum presents new high-performance vacuum pumps: Roots pumps of the HiLobe® series set new standards
Pfeiffer Vacuum, a leading global supplier of vacuum technology, presents the innovative new Roots pumps of the HiLobe series, which can be used for numerous industrial vacuum applications such as electron beam welding, vacuum furnaces or freeze-drying. The pumps in the HiLobe series are particularly interesting for rapid evacuation (lock chambers or leak detection systems). They are also suitable for use in coating applications.
Compact and powerful Roots pumps
The compact Roots pumps offer a wide nominal pumping speed range of 520 - 2,100 m³/h. This is made possible by the new drive concept in conjunction with frequency inverters. Thanks to their individual speed control, the pumps can be precisely matched to customer-specific requirements. Thanks to this powerful drive concept, the HiLobe achieves approximately 20 percent shorter pump-down times than conventional Roots pumps. Fast evacuation reduces costs and increases the efficiency of the production system.
Reliable and cost-efficient vacuum
The maintenance and energy costs of the HiLobe are >50 percent lower compared to conventional Roots pumps. The reason for this is the IE4 energy efficiency class drive and the special rotor geometries of the pumps. The sealing concept also contributes to this. The pumps are hermetically sealed to the atmosphere and have a maximum integral leakage rate of 1 - 10-6 Pa m³/s. Dynamic seals are not required, which means that maintenance is only necessary every four years. Due to the innovative sealing concept in the pump chamber, the use of sealing gas is unnecessary in most applications, which also has a positive effect on operating costs. As the HiLobe Roots pumps can also be operated at ambient temperatures of up to +40 °C with flexible air cooling, there is no need for cost-intensive water cooling.
