Activated Charcoal
Our factory specialize in the production of wood/coal columnar activated carbon, coal-based powdered carbon, mango shell activated carbon, fruit shell activated carbon, coal-based granular activated carbon, wood-based powdered activated carbon, air purification activated carbon and other types of activated carbon. The activated carbon and desulfurizing agent water purification carbon produced by the company adopt national standards and are widely used in the desulfurization of industrial gas sources such as chemical fertilizers, synthetic ammonia, urea, methanol, flue gas, various coal gases, air purification, and the early stage of industrial water and domestic water. Treatment, deep purification treatment of industrial wastewater and domestic sewage; decolorization and refining of drugs and pharmaceutical industry, etc.
Air Operated Diaphragm
DLEMA Air-Operated Diaphragm pumps are classified as reciprocating, positive-displacement-style pumps. They operate by displacing fluid from one of its two liquid chambers upon each stroke completion. To operate, the diaphragm pumps require a given amount of pressure and air volume to deliver the proper amount of fluid.
The diaphragms act as a separation membrane between the compressed air supply and the liquid. Driving the diaphragms with compressed air instead of the shaft balances the load on the diaphragm, which removes mechanical stress from the operation and extends diaphragm life. This also allows the valve balls to open and close on the valve seats, which direct liquid flow. This simple design and operation makes it easy for the operator to find the correct pressures and flows to optimize its operation.
