VS series is a single-stage oil rotary vacuum pump coupled with a direct-drive motor. ULVAC, Inc.'s simpliied design gives this lightweight pump the features of compact size, along with low vibration operation. The substantial reduction in vibration of the VS series pump can help reduce the costs associated with having to perform special foundation work in facilities where vibration can be problematic. Additionally, enhancements in both the oil circulation and cooling systems result in increased stability of pumping performance at high inlet pressures. These VS series pumps are typically used in a wide range of applications, especially those having a large number of repetitive pumping steps that cycle from atmospheric pressure, such as in the automated leak testing of parts, as well as numerous other industrial applications.
