Pfeiffer Vacuum, a provider of vacuum technology, has introduced in new Roots pumps of the HiLobe® series.
The compact pumps can be used for numerous industrial vacuum applications such as electron beam welding, vacuum furnaces or freeze drying.
The compact roots pumps offer a wide nominal pumping speed range of 520-2,100 m3/h, made possible through the new drive concept in conjunction with frequency converters.
The pumps can be tailored to customer-specific requirements utilising individual speed control. The new drive concept permits HiLobe to achieve approximately 20% shorter pump-down times than conventional roots pumps. Rapid evacuation reduces costs and increases the efficiency of the production system.
“With the HiLobe Roots pumps our customers are able to reduce energy and operating costs and consequently make production more cost-efficient. For a sustainable reduction of energy consumption and operating costs, it is not enough to solely base it on the energy requirements of a vacuum pump,” said Dr. Ulrich von Hülsen, Chief Technology Officer of Pfeiffer Vacuum Technology AG.
“The type of cooling, the maintenance intervals and the control also have a decisive influence on the overall energy balance. We are product to be able to offer our customers this holistic approach,” Hülsen continued.
The maintenance and energy costs of the HiLobe are more than 50% lower compared to conventional roots pumps, due to a drive with energy efficiency class IE4 and the special motor geometries of the pumps.
The pumps are hermetically sealed to the atmosphere and have maximum integral leakage rate of 1.10-6Pa m3/s.
