Hanchen Vacuum Pump Two Stage Rotary Vane Air Pump 2XZ-2, Speed 2L/S, 220v/380v, 27kg

The Hanchen Two Stage Direct Drive Rotary Vane Air Pump 2XZ-2 is an exceptional vacuum pump designed for various industrial applications. With its powerful capabilities, it can achieve pressures well below 10^-6 bar, making it ideal for tasks requiring high vacuum levels.

This rotary vane vacuum pump is widely utilized in a variety of fields. For instance, it plays a crucial role in providing braking assistance in large trucks and diesel-powered passenger cars that do not generate intake vacuum naturally. Additionally, it is commonly found in light aircraft to drive gyroscopic flight instruments. Its application extends to the installation of air conditioners, where it is essential for evacuating refrigerant lines. Furthermore, the pump is used in laboratory freeze dryers and in various vacuum experiments in physics.

In the vane pump mechanism, the gas being pumped is mixed with oil inside the pump. As a result, it is necessary to separate the oil externally to maintain efficiency and prevent contamination. The inlet and outlet of the pump are designed with a large chamber that may include swirl features, allowing oil droplets to fall out of the gas flow. In some designs, the inlet is equipped with a venetian blind that is cooled by room air, as the pump typically operates at a temperature around 40 K hotter than the ambient temperature. This cooling mechanism helps condense cracked pumping oil and moisture, allowing them to return to the inlet.

When used in high vacuum systems, where the inflow of gas into the pump is significantly reduced, it becomes crucial to address the concern of molecular oil back-streaming. This phenomenon can lead to contamination within the entire vacuum system, which is something all users must consider when operating the pump.

The Hanchen Vacuum Pump Two Stage Rotary Vane Air Pump 2XZ-2 stands out for its reliability and versatility in various applications. Whether you need it for automotive braking assistance, refrigerant evacuation, or scientific experiments, this pump delivers consistent performance while maintaining high standards of cleanliness and efficiency.
