The submersible sludge pump is a specialized device integrating submersible operation and sludge transportation. With a fully-sealed structure, this submersible sludge pump operates directly submerged in the medium, requiring no complex pump chambers or priming devices-an ideal choice for sewage treatment, river dredging, etc. Compliant with GB/T 13008-2018, it efficiently transports high-viscosity sludge with solid particles up to 80mm, meeting the demands of various harsh working conditions.
Product Advantages
No Priming Required: It can start operating directly by submerging into the medium, avoiding the risks of dry running and cavitation. The startup success rate reaches 100%.
Flexible and Convenient Installation: It adopts a rail-type installation method. A single person can complete the equipment relocation, and the floor space occupied is 60% less than that of horizontal pumps.
Extremely Low Noise Pollution: With an underwater operation mode, the ground noise is ≤75dB, meeting the industrial environmental noise standards.
Strong Anti-clogging Ability: The flow passage is designed to be widened. Coupled with an open-type impeller structure, the clogging rate is reduced to less than 1%.

Main Applications
Municipal Sewage Treatment
It is used for sludge discharge in the sedimentation tanks of sewage treatment plants and sludge back-flow in biochemistry tanks, suitable for working conditions with a sludge concentration of ≤55%.
River and Port Dredging
It is applied to handle the silt and sandy sludge deposited at the bottom of rivers and ports. The maximum dredging depth can reach 20m.
Industrial Sludge Treatment
It is suitable for the transportation of industrial sludge in industries like metallurgy, chemical engineering, and building materials. It can withstand high - temperature sludge with a temperature of ≤80℃.
Construction Projects
It is used for mud discharge in foundation construction and tunnel excavation, dealing with construction sludge with a sand-containing rate of ≤70%.
FAQ
Q: Is there any limit to the submergence depth of the equipment?
A: The maximum submergence depth of regular models is 20m. For special customized models, it can reach 30m to meet the needs of deep-layer dredging.
Q: How to determine the need to replace vulnerable parts?
A: The equipment is equipped with an operating status monitoring function. When the motor current fluctuates by more than 15% or the head drops by 10%, it is recommended to check and replace the vulnerable parts.
Q: What is the after - sales warranty policy?
A: The whole machine is under warranty for 12 months. The warranty for core components such as the motor and mechanical seal is extended to 18 months. During the warranty period, free maintenance technical support and fault solutions are provided.
