Product Description:

The LG Series Dry Oil-Free Screw Vacuum Pump operates using a pair of precisely engineered parallel screws that rotate synchronously in opposite directions. This mechanism creates a sequence of sealed chambers, which continuously transport gas for suction and exhaust purposes. Thanks to its innovative design, the pump functions without the need for lubrication within the working chamber, guaranteeing a clean and oil-free vacuum environment that safeguards both your process media and the surrounding environment.

Equipped with a specially designed screw structure, the pump achieves high pumping efficiency while offering a robust capacity for liquid discharge. Its short and unobstructed pump cavity ensures smooth and efficient exhaust performance. Moreover, the rotor undergoes dynamic balance correction, and the use of premium bearings contributes to stable operation characterized by low vibration and minimal noise levels.

The flow passages are constructed from corrosion-resistant materials and feature an automatic purging system, enabling the pump to handle condensable gases, water vapor, and mildly corrosive substances with ease. These qualities make the LG Series vacuum pump an excellent solution for applications involving oil and gas recovery, solvent recovery, and the processing of special gases.

Technical Parameters:

The table below presents the basic parameters for a variety of pumps from the Air Cooled Series. Each model is characterized by its pumping speed, pressure limit, power consumption, rotational speed, inlet and outlet calibers, weight, noise level, and overall dimensions.

These pumps offer a range of pumping speeds from 5 to 100 cubic meters per hour, which corresponds to 1.5 to 30 liters per second. The pressure limits vary mostly around 5 to 30 pascals depending on the model, making them suitable for different industrial or laboratory applications.

Power ratings range from 0.37 kW up to 4 kW, with revolutions per minute close to 2700-2900 rpm. The connection calibers for inlet and outlet are given using KF flange sizes, varying from KF14 up to KF63. The noise levels are maintained below 73 dB(A), ensuring relatively quiet operation for the environments where these pumps are used.

Overall, these Air Cooled Series pumps provide a versatile solution for various vacuum pumping requirements, balancing efficiency, noise level, and compact dimensions effectively for ease of installation and operation.

Applications:

Oil and gas extraction involves the recovery of valuable hydrocarbons from underground reserves. In addition to this, solvent recovery processes are employed to reclaim and reuse solvents, reducing waste and improving efficiency. Special gas recovery focuses on capturing and recycling rare or industrial gases used in various applications.

Vacuum coating techniques are widely used in industries to apply thin films on surfaces, enhancing their properties. The field of biomedicine utilizes vacuum technologies for processes such as sterilization and the creation of medical implants. Additionally, food processing industries benefit from vacuum systems to preserve freshness and extend shelf life through controlled environments.

Advanced equipment like single crystal furnaces are essential for growing high-quality crystals used in electronics and optics. Vacuum molding is a method where materials are shaped under vacuum conditions to ensure purity and precision. Similarly, vacuum smelting is employed to refine metals by removing impurities in a controlled vacuum atmosphere.

The electronics sector relies heavily on these vacuum technologies, particularly in the production of photovoltaic cells that convert solar energy into electricity. Semiconductor synthesis also depends on vacuum environments to create materials with the necessary electrical properties for modern devices.
