Axial Flow Pumps
Axial flow pumps utilize rotating impeller blades to generate lift force, enabling axial fluid transport along the shaft. Available in vertical, horizontal, inclined, and tubular (submerged) configurations, these pumps are designed for high-flow, low-head applications. Key specifications include specific speed (n) ranging from 500 to 1600 and impeller diameters of 1.6–4.5 meters.
Key Features
High-Efficiency Design
Impellers with 2–7 blades rotate within a cylindrical casing. Fixed guide vanes above the impeller convert rotational kinetic energy into pressure, ensuring smooth axial flow.
Adjustable blade angles (in large pumps) optimize efficiency across varying flow conditions, while fixed blades are used in smaller models.
Robust Construction
Dual mechanical seals prevent leakage; heavy-duty thrust bearings handle axial loads in large pumps.
Submersible motors (Class F insulation, IP68 protection) enable underwater operation with temperature and leak monitoring systems.
Wide Performance Range
Flow: 700–89,842 m³/h | Head: 0.92–15.5 m
Power: 15–1,400 kW | Voltage: 380V–10kV
Operates in water, mild wastewater (pH 4–10, ≤40°C).
Smart Control & Reliability
Supports one-to-four pump control systems with auto-switch, fault diagnostics, and remote monitoring.
Zero-flow startup requires open discharge valves to reduce power surge.
Compact & Cost-Effective
Reduces civil engineering costs by 30–40% due to submerged installation and simplified structures.
Ideal for underground pump stations, minimizing environmental impact.
Applications
Irrigation, flood control, dock drainage, and canal water level regulation.
Industrial cooling (e.g., power plant circulation systems).
High-head models for ship propulsion systems.
Technical Specifications
Parameter | Range |
Specific Speed (n)： | 500–1600 |
Impeller Diameter： | 1.6–4.5 m |
Flow Capacity： | 700–89,842 m³/h |

Common series: ZL, ZLH, ZLB (interchangeable).
Extended models: ATQZB350 to ATQZB1600.
Operational Guidelines
Pre-Startup Checks
Inspect connections, electrical systems, and pipelines for leaks.
Clear intake debris to prevent clogging.
Monitoring
Bearing temperature ≤75°C.
Observe vibration/noise; shut down immediately if abnormal.
Maintenance
Regularly check oil temperature in gearboxes.
Working Principle
The pump mimics an airfoil’s hydrodynamic lift:
Impeller blades generate pressure differentials—negative pressure on the suction side (pulling fluid) and positive pressure on the discharge side (pushing fluid).
Fixed guide vanes straighten flow, converting rotational energy into axial movement and stable pressure.
Why Choose Our Axial Flow Pumps?
