VTL series LeLe oil screw pump for large central vacuum systemsSpecially developed for vacuum applications, the twin-screw host is highly efficient and reliable; There are three conical bearings for the anode and cathode rotors at the exhaust end, one cylindrical bearing at the intake end, and a total of seven or eight bearings inside the machine head, fully ensuring the reliability of the machine head. specifically forA large central vacuum system designed oil screw pump.A new design concept for oil and gas separators, featuring multiple separation structures, gravity, cyclone, and polymerization designFilter, ultra-low exhaust oil content, less than3ppmProtect the environment and reduce lubricant consumption;Ultra low oil pressure drop, reducing exhaust back pressure, lowering power consumption, and improving overall efficiency;Single or double barrel and multi-core structures provide a larger separation and filtration area within a limited projection area;Specially developed and optimized filter cartridges, ultra-low pressure drop, more reliable sealing structure, and user-friendly design for easier disassembly and assembly;Humanized design of oil separation drum, with a drain valve at the bottom and an oil injection plug in the middle. Convenient for filling and draining oil during maintenance. adopt

Permanent magnet synchronous variable frequency motorAll models adoptIE4Grade（GB1Ultra high efficiency motor with high energy efficiency;IP55Protection level. The motor winding and magnetic steel are kept in a closed and clean space to avoid contamination and demagnetization.

Screw vacuum pump is a pumping device that uses a pair of screw rotors with opposite rotation directions to perform synchronous high-speed meshing and rotational motion in the pump casing, producing suction and exhaust effects. The use of maintenance free design technology has solved the problems of difficult and expensive maintenance of vacuum pumps. The working chamber of the vacuum pump does not require lubricating oil and sealing liquid, and can recover various condensable gases, solving the pollution problems that may be caused to the vacuum system and the environment by steam jet pumps, slide valve pumps, rotary vane pumps, liquid ring pumps, etc. At the same time, the recovered materials can also create additional economic benefits.

Key Features:

Single stage design can achieve a high vacuum of 5Pa, and can operate continuously for a long time from atmospheric to ultimate vacuum.

Single stage design can easily discharge solid waste and remove residual materials inside the pump.

The screw material is integral ductile iron with high strength and good reliability.

There is no contact or friction between the screw rotors, and the speed is high and stable.

Low noise and vibration, suitable for quiet environments such as microelectronics and semiconductors.

The pump chamber is designed with an oil-free structure, with no exhaust gas or waste liquid discharge, making it particularly environmentally friendly and energy-saving.

Screw rotors and pump chambers with special coatings can extract condensable gases and toxic and harmful gases.

Internal parts can be treated with anti-corrosion coating, which can meet the special requirements of the chemical and pharmaceutical industry.
