Features of LG Screw Vacuum Pump:
Clean and Environmentally Friendly: There is no lubricating oil in the working chamber. It is a dry vacuum pump, which is beneficial for medium recovery and can achieve a clean vacuum. During the operation process, there is no discharge of waste oil or wastewater, causing no pollution to the environment. It is an environmentally friendly vacuum device.
High Vacuum Degree: The rotor profile is optimally designed and precisely processed by a German five-axis linkage compound machining center. The ultimate pressure of a single pump is ≤1Pa. It has a large gas pumping capacity in the high vacuum area, high working efficiency, and low power consumption.
Optional Anti-corrosion Design: According to different pumped media, the flow-through components offer various materials and anti-corrosion coatings for selection, such as titanium materials, stainless steel, nano-ceramics, NIP alloy spraying, etc. It is suitable for use in corrosive environments in industries like pharmaceuticals and chemicals.
Capable of Pumping Condensable Gases and a Small Amount of Dust-laden Gases: The pump chamber of the screw pump is designed with an automatic gas suction and purging device, which can prevent the deposition of a small amount of dust in the pump chamber and is applicable for pumping gases containing a small amount of dust.
Special Shaft Seal Design to Prevent Mutual Contamination between the Pumped Medium and the Lubrication System: This special design effectively prevents the mutual penetration and contamination between the lubricating oil in the gear chamber and the medium in the pump chamber, achieving a truly dry vacuum and extending the service life of main components such as pump bearings and gears.
LGP Type with Variable Pitch for Energy Saving and Low Noise: The variable pitch of the rotor profile is optimally designed, and the energy-saving effect is remarkable. For example, when the 110L/S screw pump is used with an inlet pressure within 1000Pa, the power is approximately around 5KW, and the noise is ≤79dB without noise reduction equipment.
Overload Protection Design: The screw pump with variable pitch is equipped with a variable frequency speed regulation design and can be started and operated under any pressure.
Smooth Operation: The rotor undergoes a G1 fine dynamic balance test, resulting in smooth operation and small vibration.
High-standard Configuration: bearings are adopted, the synchronous gears are grade 5 gears manufactured by Hangzhou Gear Works, and the coupling is of German standard.
Complete Accessory Configuration: The screw pump is equipped with a variety of accessories in its design, including an inlet filter, an outlet muffler, an outlet cooling and recovery device, a temperature sensor, a mobile frame, etc., which can be selected according to different working conditions required by customers.
Targeted and Differentiated Design for Different Industries: Our company's screw pumps are specially designed with differentiation for the different process conditions in the pharmaceutical, chemical, and electronic industries. The LGP variable pitch screw pump series features a high vacuum degree, low energy consumption, low noise, and a design to prevent dust deposition. It is an updated replacement for the H, 2H slide valve pump series and the 2X vane pump series. The flow-through part of the LGF anti-corrosion screw pump series can be treated for anti-corrosion, and it can pump a large amount of water vapor and various corrosive media. The exhaust port's cooling, recovery, and noise reduction design is clean and environmentally friendly, making it suitable for harsh working environments such as those in the chemical and pharmaceutical industries. It is an updated replacement for the vertical reciprocating pumps and water ring pump series in the chemical industry.
High-quality and Sound Supply of Spare Parts: Using our company's screw pumps can avoid the drawbacks of imported screw pumps, such as expensive spare parts, long supply cycles, and the inability to receive timely maintenance, which may even lead to the situation where customers cannot carry out normal production.
