Product Description
The LGB dry screw vacuum pump is a marvel of engineering, featuring a meticulously crafted working chamber formed by parallel spiral rotors and a robust pump body. This ingenious design creates multiple sealed chambers between the rotors and pump body, delivering superior performance. As the rotors rotate in perfect harmony at high speeds, propelled by a synchronous gear within the pump housing, they expertly guide the gas in each sealed chamber from the inlet to the exhaust end. This process generates powerful suction and efficient exhaust. Remarkably, the working chamber operates without any medium, eliminating the need for water sealing or oil lubrication. This results in a pristine vacuum environment, capable of extracting condensable gases and those with minimal dust content. With its impressive ultimate vacuum levels and low power consumption, it epitomizes energy efficiency and cost-effectiveness. The pump shines exceptionally in industries like semiconductor and electronics, where oil-free, clean vacuums are paramount, and it plays a crucial role in solvent recovery processes within the chemical and pharmaceutical sectors. Celebrated for its versatility, screw vacuum pumps find extensive applications across various industries, including chemical and pharmaceutical, electrical, lithium battery, photovoltaic, industrial furnaces, aerospace, vacuum coating, metallurgy, and drying.

Features
--Experience the efficiency of an oil-free pump chamber, ensuring a contamination-free vacuum system that enhances product quality. Say goodbye to oil emulsification issues and the hassle of frequent fluid replacements, while minimizing maintenance costs. This powerful unit achieves a remarkable 5pa on its own and can seamlessly integrate with Roots pumps,
molecular pumps, and more to create an advanced oil-free system delivering superior vacuum capabilities.
--Our vacuum pump's performance remains consistently stable, unaffected by changes in water or ambient temperatures.
--Overcurrent components such as the pump chamber and screw rotor
can be enhanced with nickel phosphorus coatings and Hastelloy alloy infiltration,
making them adept at handling corrosive media. Ideal for chemical and pharmaceutical applications including product distillation, drying, and degassing.
--Effortlessly discharge extracted gases directly from the pump body,
eliminating environmental pressure concerns and simplifying gas solvent recovery.
--Designed for easy maintenance, the pump allows for straightforward cleaning. Simply open the suction and exhaust ports, initiate the pump, and introduce water or cleaning agents from the suction port for a quick clean, no disassembly required.
