Summary:
The 2SK/SK vacuum pump is designed to handle air and other gases that are slightly corrosive, insoluble in water, and contain minimal solids. It's commonly used in applications where gentle suction is required, such as in milking machines or sewage systems.
The pump operates by using water that rotates at high speed, creating pressure and a sealed cavity to remove air from the suction side of the system.
This double-stage vacuum pump offers higher vacuum levels, faster pumping speeds, a compact design, reliable operation, and easy maintenance.
China-made vacuum pumps are widely used in industries like food processing, textiles, medicine, and chemical manufacturing, as well as in processes such as dipping, drying, and more.

Aluminium solar panel frames are used to hold and protect solar panels. They are made of lightweight, durable aluminium and are designed to withstand harsh weather conditions. The frame is typically made up of four sides that are connected together to form a rectangular shape. The solar panel is then mounted onto the frame using brackets or clamps. The frame serves as a protective barrier for the solar panel, preventing damage from wind, rain, and other environmental factors. It also provides a secure mounting point for the panel, ensuring that it stays in place and functions optimally. Aluminium frames are a popular choice for solar panels due to their strength, durability, and resistance to corrosion.
