Chemical wastewater often contains flammable, explosive, or toxic substances; when these substances vaporize into the air, they can turn the surrounding area into Zone 0. Fires and explosions can occur frequently, so it is crucial for companies to use explosion-proof electrical equipment.

In recent years, domestic chemical and pharmaceutical companies have sought to reduce safety distances and the amount of land required, and as a result they are converting to underground tanks for storing chemical substances, transporting these substances from the tanks to workshops or areas on the surface. The traditional method of transportation involves using negative pressure suction devices, but this approach suffers from problems such as air resistance and cavitation, which reduce efficiency and cause environmental pollution; in cases where the substance has a low density, it may not even be possible to pump it up. The green-label explosion-proof chemical submersible pumps developed by Tianjin Jiamax Electric Submersible Pump Co., Ltd. meet the requirements for use in zero-zone environments and are commonly used in underground tanks. Their positive pressure propulsion mechanism helps to overcome issues like air resistance and cavitation. The green-label \"chemical submersible pump\" uses positive pressure to deliver nearly a hundred types of chemical fluids; it has obtained an Exds II BT4 Ga explosion-proof certification. It overcomes the traditional negative-pressure suction process and addresses various technical challenges such as air resistance and cavitation. It meets the requirements for use in zero zones and complies with standards such as GB3836.1-2010*. In 2004, Tianfu Group invested 20 million RMB to restructure Tianjin Jiamah Machinery Factory, setting its business focus on the development of light oil submersible pumps. The technical personnel are all experienced professionals who have spent many years engaged in the design, development, production, and quality control of submersible electric pumps for crude oil, and who possess expertise in related technologies. Through a decade of unremitting efforts, Tianjin Jiamah Machinery Factory has achieved remarkable results. It has thousands of users and nearly 400 distributors, with annual sales revenue exceeding 30 million yuan. In 2012, it was restructured and renamed Tianjin Jiamaa Submersible Pump Co., Ltd. In 2015, the vice presidents of Red Jacket and Blue Jacket in the United States came to our company to discuss potential cooperation ； New models of submersible pumps are developed each year for various media (the list is continuously expanding): Maintenance-free, explosion-proof green-label chemical submersible pumps are suitable for handling gasoline, diesel, kerosene, aviation kerosene; mixtures of methanol or ethanol with gasoline; 100% methanol, ethanol, ethylene glycol, (n)-butanol, pentanol, isopropanol, benzyl alcohol, n-hexanol, n-octanol, diethylene glycol, cycloethanol, etc.; methyl acetate, ethyl acetate, vinyl acetate, butyl acetate, n-propyl acetate, ethyl propionate, (n)-butyl acrylate, isooctyl acrylate, methyl salicylate, methyl oleate, diethyl phthalate, dimethyl carbonate, etc.; toluene, xylene, crude benzene, styrene, heavy aromatics, 100# aromatics, 150# aromatics; dichloromethane, n-hexane, propylene glycol methyl ether, petroleum ether, **furan, diethylene glycol monobutyl ether, etc ； Take a look at 13863819391.
