    Leybold RUVAC WAU 501 Roots Type Booster Blower Vacuum Pump Rebuilt Refurbished

    RUVAC WA/WAU, WS/WSU

    The series WA/WAU Roots vacuum pumps are provided with directly flange-mounted air-cooled standard three-phase motors. The oiled radial sealing rings of the RUVAC WA/WAU for sealing the shaft against the atmosphere are made of FPM (fluor caoutchouc).

    The WS/WSU series pumps are driven by air or water-cooled canned motors.

    Roots vacuum pumps of the series WAU/WSU are provided with an additional integrated pressure equalization line and a differential pressure valve.

    Pumps from these series are supplied with a vertical pumping action as standard.

    Advantages to the User

    • Two air-cooled series, each with four models
    • Reliable and trouble-freeSealing rings with their housing Shaft seals and elastomer seals  Air-cooled standard motors in accordance with IEC dimensions eg. NEMA dimensionsmade of FPM/Vitoncan be readily replaced
    • Easy to exchange with custom motors
    • Integrated pressure equalization line for protection against overloading at high pressures on WAU models
    • Pumping direction may be changed as required
    • ATEX versions compliant to 94/9/EC possible

    Typical Applications

    • For oil-free compression of gases and vapors in combination with a backing pump
    • Short cycle pumping processes also in the presence of large quantities of gas and vapor
