Low-energy models join this family of vacuum screw pumps
Leybold
This company has recently added several new products to its dry, compressing Dryvac Series of vacuum screw pumps (photo). The new Dryvac DV 200 and DV 300 pump sizes complement the existing product range of Dryvac 450, 650 and 1200, and offer the same benefits for applications that require a smaller pump size. These pumps feature low constant power consumption, and due to an optimized screw rotor design, the DV 200 and DV 300 minimizes power consumption, reducing both costs and carbon footprint for the operator. Able to operate reliably under harsh conditions and handle vapors, dusts and particles, these pumps are equipped with an automatic shaft-seal-purge control for optimal protection of shaft seals and bearings. Fieldbus and programmable logic controller (PLC) compatibility allow for connectivity to other devices, enabling realtime communications and control. — Leybold GmbH, Cologne, Germany
