ZJ Roots vacuum pumps

Roots vacuum pumps have ZJ series and ZJP series, provide 150-10,000L/s pumping speed with 5×10⁻² Pa ultimate pressure, It is a kind of roots vacuum pumps in which a couple of lobed rotors turn like 8-shape in high speed synchronously. Two rotors rotate and produce aspiration and exhaust which principle is just like a roots blower. But it can not discharge the gas to atmosphere directly and requires to be used with a fore vacuum pump in series connection.

Unveiling the Versatile ZJ Roots Vacuum Pumps: Precision Engineering for Superior Performance

ZJ Roots vacuum pumps are meticulously engineered with synchronized lobed rotors, resembling an 8-shaped configuration, to deliver unparalleled performance. Operating akin to a roots blower, these pumps generate aspiration and exhaust, offering a higher compression ratio ideal for various applications. However, to discharge gas effectively, they require a series connection with a fore vacuum pump.

Applications:

Widely utilized across industries such as vacuum molding, smelting, gas pumping, coating, distilling, and drying, ZJ Roots pumps excel in demanding environments. Their resilience to dust makes them indispensable in chemical and pharmaceutical processes.

Key Advantages:

  1. Perfect Dynamic Balancing:
    • Precision engineering and careful rotor balancing ensure stable operation, low noise, and minimal vibration.
    • High geometric symmetry and precision machining of pump components guarantee optimal performance.
  2. Robust Drive and Operating Parts:
    • Carefully balanced operating parts enable continuous operation under varying pressure conditions.
    • Quick startup capabilities and rapid attainment of ultimate pressure enhance efficiency.
  3. Oil-Free Operation:
    • Elimination of contact between rotors and the pump house eliminates the need for lubrication, preventing oil vapor contamination in the vacuum system.
  4. Reliability and Auto-Protection:
    • Inherent overflow valve provides auto-protective features, ensuring reliability and system integrity.
  5. Compact Design with Convenient Installation:
    • Compact footprint and multiple gas outlet ports (left, right, and under the pump house) facilitate easy installation, saving space and enhancing usability.
