Your Selection Guide
A 2-stage rotary vane vacuum pump is a device designed to remove air and gases, achieving a deeper vacuum in two phases. It's a widely used, fundamental type of vacuum pump for various applications needing a strong vacuum, such as in scientific research, manufacturing, and processing industries. Its two-stage operation allows for efficient and effective vacuum creation, making it a reliable choice for demanding tasks.
Selection should be based on specific application requirements, including the desired vacuum level (ultimate pressure), flow rate (capacity), compatibility with processed gases, and operating environment. Considerations include the pump's ultimate vacuum capability, pumping speed at your working pressure, oil type for compatibility with processed gases, and additional features such as gas ballast for moisture handling. Consulting with the manufacturer or a specialist can also help in selecting the most suitable pump.
Yes, these pumps can handle air and most non-corrosive gases. However, the compatibility of the pump with specific gases should be verified to ensure proper operation and avoid damage to the pump.
Yes, ensure proper ventilation and handle the pump's oil and evacuated materials according to environmental regulations to minimize impact. Additionally, using an oil mist filter is recommended to capture oil vapors from the exhaust, preventing their release into the atmosphere and maintaining a cleaner working environment.
Regular maintenance, following the manufacturer's operating guidelines, using the correct oil, and promptly addressing any issues are crucial steps to ensure the pump's longevity and reliable performance.
Our vacuum pumps' quality is significantly enhanced by using premium materials from Japan for rotary vanes, durable seals from Germany and America, and reliable motors from top international brands. These choices ensure high performance, longevity, and customer satisfaction.
Yes, most of our oil-sealed rotary vane vacuum pumps are designed to operate efficiently across a wide voltage range from 220V to 440V, accommodating various power supply conditions without compromising performance or safety. This feature ensures reliability and flexibility for diverse industrial applications and geographical locations.
3. How does the gas ballast function enhance the performance of oil-sealed rotary vane vacuum pumps?
The gas ballast function introduces a small amount of air into the pump during the compression phase to prevent condensation of vapors within the pump oil. This is crucial for applications involving moisture or solvent vapors, as it helps maintain the pump's efficiency, protects the oil's quality, and extends the pump's lifespan.
Our standard oil-sealed rotary vane vacuum pumps are not designed for handling highly corrosive gases, as market demand for such specialized pumps is currently not our focus. However, for applications involving explosive gases, we offer models equipped with ATEX-certified motors to ensure safe operation in potentially hazardous environments. For environments with mild corrosive gases, we recommend a compromise solution that involves more frequent oil changes to mitigate the corrosive effects on the pump's internal components, maintaining performance and extending service life.
The oil mist filter for oil-sealed rotary vane vacuum pumps serves a dual purpose: it captures oil mist expelled during operation, preventing environmental contamination and workplace exposure, and it recycles the captured oil back to the pump. This recycling mechanism is a significant feature, as it conserves oil by reintegrating it into the pump's operation, ensuring efficient use of resources and reducing the need for frequent oil top-ups.
The oil in oil-sealed rotary vane vacuum pumps should generally be changed every 3 months. However, this can vary based on the pump's usage intensity, the type of processed gases, and operating environment. Regularly checking the oil's condition for any signs of contamination or degradation can help tailor the change frequency to your specific needs.
