Environmental Protection Industry
In response to the national call, Helsh-Tech rotary pumps accelerate the promotion of sludge harmless disposal and resource utilization. Based on sludge reduction treatments such as sludge thickening, conditioning, and dehydration, according to the sludge production volume and quality, rubber rotary pumps are extensively used in the environmental protection industry, including sewage treatment in wastewater treatment plants and chemical enterprises, as well as waste discharge from high-speed railways and vacuum drainage in subway systems. Helsh-Tech rubber rotary pumps leverage professional manufacturing technology to serve the environmental protection sector by conveying sewage and sludge. Characteristics of this pump: It is a self-priming conveying pump that is widely used in wastewater treatment plants. Coupled with Helsh-Tech Fluid Technology's innovative rubber rotary pumps, especially our company's rubber rotor manufacturing process, which produces one-piece rotors, the craftsmanship of each pump component is refined. The rubber rotor material is rigorously selected, including EPDM, fluoroelastomer, silicone rubber, etc. Its process ensures durability in use and prevents rubber from falling off, featuring strong self-priming ability, wear resistance, corrosion resistance, etc. The working chamber is equipped with wear-resistant and corrosion-resistant lining plates that are easy and quick to disassemble, replace, and update, meeting the fluid conveying needs for various sewage and sludge compositions in wastewater treatment plants.
Service Cases
Sewage Rubber Rotary Conveying Pump
In the field of traditional process equipment, the service life of sewage conveying pumps is much longer than traditional pump types. Our sewage conveying pumps are widely used for conveying activated sludge, sludge return, and other fluid substances. Depending on the production industry, sludge content varies, typically around 2%. The pump's operating principle utilizes the pump chamber volume and specially designed rotor movement to create variations, achieving ideal strong suction for continuous conveyance. This pump is specially designed with high and complex manufacturing processes, not only achieving super strong self-priming ability but also capable of forward and reverse rotation, with high conveying efficiency, convenient maintenance, and low costs.
Sludge Conveying Pump
As the country develops and strengthens its management of environmental awareness, sludge treatment technology continues to improve, commonly including sludge thickening, sludge dehydration, and sludge oxidation digestion technologies. Based on sludge reduction treatments such as sludge thickening, conditioning, and dehydration, the water content of sewage decreases from 99% to 95%. Based on sludge dehydration technology, the water content of sludge decreases from 95% to 80%. After sludge thickening treatment, adsorbed water and capillary water in the sludge are separated. After dehydration, the sludge volume is greatly reduced, not only reducing secondary environmental pollution but also turning waste into treasure. Proteins extracted scientifically from sludge using physical, chemical, and biological methods are used in animal feed, crop fertilizers, etc. They are also used for land utilization, building materials, soil fertilization, emergency filling, etc. This pump creates favorable conditions for sludge transportation, disposal, and comprehensive utilization.
Subway and High-Speed Railway Sewage Conveying Pump
Helsh-Tech rotary pumps also utilize new sewage disposal technologies to aid in sewage disposal and conveyance. As one of the sewage disposal equipment, Helsh-Tech rotary pumps achieve stable operation, convenient and quick use, and long service life, effectively reducing costs for China's transportation industry, shortening customer waiting times, and significantly reducing labor for operators. At the same time, they effectively replace traditional underground sewage conveyance methods.
High-speed railway sewage is centrally treated and discharged to designated stations through advanced integrated equipment, using vacuum piping suction methods to transport it to underground sewage pipes. Chemical precipitation and biological methods are employed for effective treatment. Our company's rotary pumps, paired with integrated sewage removal systems, achieve ideal conveyance effects, meeting requirements for high efficiency, fast speed, strong suction, and environmental protection.
