8" HighFlow Hydraulic Submersible Axial Pump


Product Model: QSB50015200G

The QSB50015200G Hydraulic Axial Flow Pump is a submersible drainage device powered by hydraulic energy, designed for the high-capacity transfer of clean or turbid water. The pump body is manufactured using an integral stainless steel casting process, providing the overall structure with wear and corrosion resistance. It is suitable for operational scenarios requiring rapid deployment of high-capacity pumps, such as urban flood control, garage and tunnel drainage, and river water transfer. This equipment features an 8inch discharge outlet, a maximum flow rate of 500 m³/h, and a head of 15 meters. The internal flow channel is optimized to enhance hydraulic efficiency while maintaining a compact profile. The entire pump adopts a lightweight design and is equipped with a foldable carrying handle, facilitating onsite transfer and rapid deployment by personnel. This pump can be driven by a compact 35HP-class hydraulic power unit. The hydraulic power transmission method allows the pump to operate fully submerged while the power source remains on the bank, adapting to emergency drainage needs in complex environments.

Core Advantages
Integral Stainless Steel Casting: The pump body is made of integral cast stainless steel, offering wear and corrosion resistance, making it suitable for long-term use in both clean and turbid water environments.
High-Capacity Drainage Capability: With a maximum flow rate of 500 m³/h and a head of 15 meters, it meets the requirements for rapid, large-volume water extraction in scenarios like urban flood control, tunnels, and garages.
Compact and Lightweight Design: Features a compact overall structure and light weight, equipped with a foldable carrying handle for easy one-person handling and installation in confined spaces.
Low Power Drive Requirement: The optimized internal flow channel design requires only a 35HP hydraulic power unit for operation, reducing equipment (ancillary) costs and transportation difficulty.
Rapid Deployment Capability: The pump, without an integrated motor, can be directly placed into the water for operation while the power unit remains on the bank, shortening onsite preparation time.

Application Scenarios
Urban Flood Control and Drainage: Used for rapid removal of accumulated water from low-lying urban areas, underpasses, and the bases of overpasses.
Underground Garage Drainage: Suitable for clearing rainwater backflow and accumulated water in places such as underground garages and basements.
Tunnel and Culvert Drainage: Used for construction dewatering and routine maintenance drainage in road tunnels and railway culverts.
River Water Transfer and Dredging: Applicable for temporary water transfer, diversion, and low-head conveyance in small to medium-sized rivers.
Emergency Rescue Operations: Paired with a hydraulic power unit to achieve high-capacity rapid drainage at flood disaster sites.
Agricultural Irrigation and Drainage: Used for temporary drainage of waterlogged lowlying farmland and the conveyance of irrigation water.


Made entirely of stainless steel, it is wear-resistant and corrosion-resistant. The overall design is compact and lightweight, with an optimized internal flow channel design. It can be driven by a regular 35-horsepower small hydraulic power station. The maximum drainage flow rate is 500m³/H, the head is 12m, and the design features a folding handle for easy handling.


Hydraulic axial flow pumps are primarily suitable for operation in clean or turbid water environments. They are compact, lightweight, and offer the advantage of rapid deployment. Constructed entirely of stainless steel in a single piece, they are durable, easy to operate, require virtually no maintenance, and are lightweight and reliable. They are used for drainage in urban flood control, garages, tunnels, and other similar applications.
