Portable High Performance Direct-Drive Rotary Vane Vacuum Pump

Here is the improved and rewritten English version of your content, with added details to make it more natural and comprehensive: --- --- **2XZ Series Direct-drive Rotary Vane Vacuum Pump** The 2XZ series vacuum pumps are essential equipment for removing air from sealed vessels. These pumps can be used independently or as a forepump, process pump, or support pump for booster pumps, diffusion pumps, and molecular pumps. They are widely applied in electrical vacuum cases, vacuum sealing, printing, photoengraving, food packaging, vacuum forming, refrigeration equipment repair, and laboratory instruments. This series of pumps is particularly popular in industries such as aerospace, semiconductors, coating, food packaging, drying machines, refrigeration systems, scientific research, medical treatment, electronics, chemicals, and university laboratories. ### Key Features: - **Compact design**: Small size, lightweight, and low noise. - **Gas ballast valve**: Designed to handle small amounts of water vapor. - **Oil anti-suckback device**: Prevents oil backflow during operation. - **Versatile applications**: The 2XZ-2 model is ideal for small-bore systems, while the 2XZ-4 model is suitable for vacuum drying ovens, freeze dryers, and printing machines. - **Flexible connections**: Equipped with small-bore adapters and KF flanges for easy integration. ### Technical Specifications: | Parameters / Model | 2XZ-0.25 | 2XZ-0.5 | 2XZ-1 | 2XZ-2 | 2XZ-4 | |-------------------|----------|---------|-------|-------|--------| | Pumping Speed (m³/h) | 0.9 (0.25) | 1.8 (0.5) | 3.6 (1) | 7.2 (2) | 14.4 (4) | | Pumping Speed (L/s) | 0.25 | 0.5 | 1 | 2 | 4 | | Ultimate Pressure (Pa) - Partial | ≤6×10⁻¹ | ≤6×10⁻² | ≤6×10⁻² | ≤6×10⁻² | ≤6×10⁻² | | Ultimate Pressure (Pa) - Total | ≤6.5 | ≤1.33 | ≤1.33 | ≤1.33 | ≤1.33 | | Rotating Speed (r/min) | 1400 | 1400 | 1400 | 1400 | 1400 | | Motor Power (kW) | 0.12 | 0.18 | 0.25 | 0.37 | 0.55 | | Voltage (V) | 220 | 220/380 | 220/380 | 220/380 | 220/380 | | Inlet Diameter (O.D.)
