OIL ROTARY VACUUM PUMP VS1501, VS2401 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. Low Vibration The unique single-stage vane design used in the VS pumps permit the use of a high-speed motor (1500 rpm at 50 Hz, 1800 rpm at 60 Hz) that help to significantly reduce vibration levels in the low frequency range. This pump can largely eliminate the need for special foundation work and can be more easily installed on the upper floors of most buildings. Lightweight and Compact Compared to industrial standard oil rotary type pumps, the VS2401 is roughly 35 % lighter, requires roughly 20 % less floor space, and is only half as tall, making it extremely lightweight and compact.
