Features:

Clean and Environmental Friendly: Oil-free work chamber, dry vacuum pump, beneficial for medium recovery, providing clean vacuum. No waste oil or wastewater discharge during operation, non-polluting to the environment, an eco-friendly vacuum equipment.
High Vacuum Level: Optimized design of the rotor type line, precision machined with a German 5-axis simultaneous composite processing center, single pump ultimate pressure ≤ 1Pa. Large vacuum extraction volume in high vacuum area, high work efficiency, low power consumption.
Corrosion-Resistant Options: Available in various materials for different exhaust mediums, the flow components include titanium, stainless steel, nano-ceramic, and NIP alloy coatings, offering multiple corrosion-resistant finishes. Suitable for use in corrosive environments such as the chemical industry.
Removable for volatile gases and a small amount of dust-laden gases: The screw pump chamber design includes an automatic intake and blow-off device, preventing dust accumulation within the pump chamber and suitable for extracting gases containing a small amount of dust.
Special shaft seal design, prevents cross-contamination between the pumped medium and the lubrication system: This unique design effectively prevents the gear chamber lubricant from permeating and contaminating the pump chamber medium, achieving true dry vacuum and extending the service life of critical components such as pump bearings and gears.
LGP Type Variable Pitch Energy-Saving Low Noise: Optimized design with variable pitch rotor profile, significant energy-saving effect. For instance, the power of a 110L/S screw pump is nearly 5KW when used within an inlet pressure of 1000Pa, and the noise level without silencing equipment is ≤79dB.
overload protection design: Variable pitch screw pump with variable frequency speed regulation design that can start and operate at any pressure.
Operation Smooth: The rotor undergoes G1 precise dynamic balance test, with minimal vibration during operation.
High-standard configuration: Bearings are SKF, synchronous gears are 5th grade gears manufactured by Hangchi, and couplings are of German standard.
Comprehensive accessory package: The screw pump comes with a variety of accessories including an inlet filter, exhaust silencer, exhaust cooling recovery unit, temperature sensor, and mobile frame. These are available for customers to select according to different operating conditions.
Targeted and differentiated design for various industries: Our screw pump is specially designed with differentiation for different process conditions in the chemical and electronic industries. The LGP variable pitch screw pump series boasts high vacuum, low energy consumption, low noise, and a dust-proof design. It serves as an upgrade and replacement for the H, 2H slide valve pump series and the 2X vane pump series. The LGF anti-corrosion screw pump series allows for anti-corrosion treatment of the flow section, capable of removing large amounts of steam and various corrosive media. The exhaust port features cooling and noise reduction design, making it clean and environmentally friendly, suitable for harsh working environments such as in the chemical industry. It is an upgrade and replacement for the vertical reciprocating pump and water ring pump series in the chemical industry.
Robust spare parts supply: Utilize our company's screw pump to avoid the drawbacks of importing expensive parts for screw pumps, such as long supply cycles and delayed repairs, which can lead to clients' inability to produce normally.
