A sludge vacuum pump (also known as a pneumatic solid vacuum conveying pump) is a high-suction pneumatic vacuum extraction system. In the field of environmental engineering, this device excels in operating under negative pressure, enabling efficient suction of wastewater and solid sludge from sedimentation tanks, sewage channels, or other related facilities at depths of up to -6 meters. Its delivery rate can reach up to 250 liters per minute. The system can also be paired with various robots to perform risk-free cleaning tasks.

In contrast, a centrifugal pump has a built-in power supply system, allowing it to operate independently without an external power system. It provides even stronger suction than the sludge vacuum pump. In environmental engineering, this powerful suction allows for highly efficient extraction of waste materials, making it more effective in cleaning stubborn contaminants and solid waste.

The supporting remote-controlled loader robot system further enhances safety and operational efficiency. Not only can it replace human workers in confined spaces such as sedimentation tanks and sewage channels, but it also features a telescopic robotic arm capable of multi-angle, comprehensive cleaning and recovery of wastewater and sludge—completely eliminating the safety risks associated with traditional manual extraction.
