Hanchen Vacuum Pump Two Stage Rotary Vane Air Pump 2XZ-4, Speed 4L/S, 220V/380V, 30kg Weight

The Hanchen Vacuum Pump 2XZ-4 is a high-performance rotary vane vacuum pump designed for a range of applications where reliable vacuum generation is essential. This two-stage pump efficiently reaches pressures well below 10^-6 bar, making it ideal for various industrial and laboratory settings.

With a pumping speed of 4 liters per second, the Hanchen vacuum pump is versatile enough to be utilized in braking assistance for large trucks and diesel-powered passenger vehicles. It effectively serves as a braking booster where engine intake vacuum is insufficient. Additionally, this pump finds applications in light aircraft, driving gyroscopic flight instruments, and in the evacuation of refrigerant lines during air conditioning installations.

Moreover, the pump is also used in laboratory freeze dryers and various vacuum experiments in physics, showcasing its adaptability across multiple domains.

One important aspect of the operational design of the Hanchen vacuum pump is its oil management system. In the vane pump, the pumped gas and oil mix within the pump, necessitating an external separation process. This is achieved through a large chamber at the inlet and outlet, allowing oil droplets to fall out of the gas stream. Sometimes, the inlet is equipped with a venetian blind that is cooled by ambient air to condense any cracked pumping oil and water back into the system.

When used in high vacuum systems, where the inflow of gas into the pump is significantly low, the risk of molecular oil back-streaming can pose a contamination threat to the entire system. Therefore, careful consideration must be given to pump maintenance and operational parameters to ensure optimal performance and minimal contamination.

In summary, the Hanchen Vacuum Pump 2XZ-4 stands out for its robust design and wide range of applications. Its efficient performance, combined with thoughtful engineering features, makes it a reliable choice for professionals seeking high-quality vacuum solutions.
