​HS two-stage rotary vane vacuum pump is one of the basic equipment for pumping. The pump has a dual-stage direct-coupled structure, and its working performance is composed of two parts: high-pressure stage and low-pressure stage. Its suction port is connected to the vacuum equipment, and when running, it draws in and discharges a large amount of gas from the container. When the equipment achieves a vacuum, the high-pressure stage exhaust valve will be closed, and the gas sucked in by the high-pressure stage is transferred to the second stage and discharged through the second stage to the vacuum equipment. High speed, small size, compact structure, and convenient mobility. 
It uses metal blades and is suitable for the front stage pump of a diffusion pump and supporting precision instruments. Widely used in laboratories,pharmaceuticals, food packaging, electronics, and other fields.
