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.

Features

  • 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.
  • Quiet-running Performance
    ULVAC incorporates the use of a mechanism reducing
    operating noise when pumping at ultimate pressure. Noise
    levels are reduced to 74 dB (characteristic A) for both
    the VS1501 and VS2401 models. (Values measured at
    ultimate pressure while using an oil mist trap at a distance
    of 1 meter to the side of the pump.)
  • Evaporation, sputtering, and ion plating
  • Vacuum packing, vacuum adsorption, and transport
  • Vacuum molding and vacuum casting
  • Vacuum heat treatment furnaces, sintering furnaces, and
    brazing furnaces
  • Vacuum drying, freeze drying, and vacuum degassing
  • Gas substitution, filling, and vacuum heat insulation
  • Automated leak testing VS2401
  • Easy Maintenance
    Checking, adding, and changing oil are conducted at one
    end of the VS pump.
    Amount of time between oil additions can be extended.
    The VS oil capacity is variable over a range of 8 (min) to
    10.5 (max) liters.
