Vertical long-shaft pump is a kind of Centrifugal Pump. From the perspective of centrifugal pump, it is based on the improvement of the performance of the submerged pump, making its performance much higher than that of the submerged pump, and its running stability is stronger. . Advanced and mature vertical long-shaft pump developed to meet domestic market demand. The pump can be used to transport clean water, rainwater, iron oxide water, sewage, corrosive industrial wastewater, seawater and other liquids below 55°C; after special design, it can transport liquids at 90°C. Widely used in water companies, sewage treatment plants, power plants, steel plants, mines and other industrial and mining enterprises, as well as municipal water supply and drainage, flood control and drainage projects.

Pneumatic double diaphragm ceramic gate valve is mainly applied to the pipeline of feeding and discharging system for dry power. Not only selecting the toughening ceramic as sealing material, but also applying  the valve disc auto-rotate structure and self-sealing structure realized by spring flexible autofrettage pressure.So that the sealing surface within the dry power get even wear when the valve is opened and closed frequently, which  guarantee the high sealing performance of the valve and the long work life .
Function and Application
This valve is mainly used in the ash conveying pipeline system of thermal power plant, paper industry ,steel industry and coal chemical industry as the opening and closing element.
The applicable medium is :dry ash,dust ,lime-ash etc.
The working pressure of this valve :0.6MPa~1.6MPa,
Working temperature : <=180ºC,
Air supply pressure :0.4MPa~0.6MPa.
This valve is installed horizontally, and the non-sealing face is installed downward.
