In recent years, domestic chemical and pharmaceutical companies, seeking to reduce safety distances and the amount of land required, have been upgrading their systems by using underground tanks to store chemical substances, with the substances being transported to workshops or areas on the ground surface. The traditional method for transportation involves using negative pressure suction devices; however, this approach suffers from issues 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 using this method. The \"Green Label\" chemical submersible pumps use positive pressure to transport nearly a hundred different types of chemical substances. They have obtained an Exds II BT4 Ga explosion-proof certification, thereby overcoming the limitations of traditional negative pressure suction methods and resolving various technical problems related to air resistance and cavitation. It meets the requirements for use in zero zones and complies with standards such as GB3836.1-2010*. The green-label chemical submersible pumps produced by Tianjin Jia Ma Submersible Pump Co., Ltd. have the following features: 1. They can transport more than 170 types of lightweight, flammable, and explosive materials. Thanks to the vacuum inside them, their casings feature a special explosion-proof design, enabling them to reach an equipment protection level (EPL) of Ga; such pumps can be used in Zone 0 environments (note: this refers not only to the Gb level specified in explosion-proof standards). 2. The submersible pump is integrated with the motor, resulting in a small size and ease of movement, which helps to save space in the tank area and reduce land costs; it also reduces the required fire safety distances, thereby enhancing safety. 3. The material is pushed forward under positive pressure, with no air resistance; the rapid flow of liquid on the inner and outer surfaces of the stator helps to cool the motor, allowing it to operate at low temperatures without any heat generation during operation. An internal temperature protector is built in, which shuts down the motor automatically when the current exceeds normal levels in case of faults, ensuring safety and reliability in flammable and explosive environments. 4. Due to its short axis of several hundred millimeters, it requires no maintenance, is energy-efficient, operates smoothly with almost no wear and tear, has an extremely long service life, results in very low usage costs, is hassle-free, and improves efficiency. . . . . . . The maintenance-free operation, long service life of chemical pumps – all of these are achieved by the Green Label chemical pumps. Let’s go and get to know him. Learn from him, use him. Looking forward to more new products being released. May our lives be better.
