Floating Axial Flow Pump

Denor Floating Axial Flow Pump – Adapts to Fluctuating Water Levels, Cuts Costs by 60%

The Denor Floating Axial Flow Pump extends the proven reliability of traditional axial flow pump technology into environments where water levels are never constant. By mounting the pump assembly on a robust pontoon, this system floats directly on the water surface, automatically rising and falling with changing water levels.

This innovative design eliminates the need for fixed intakes, complex foundations, or hydraulic structures—making it the ideal solution for reservoirs, lakes, rivers, and emergency flood control applications. Whether you need temporary pumping during construction, seasonal irrigation, or rapid deployment for disaster response, the Denor floating axial flow pump delivers high-volume, low-head performance with unprecedented flexibility and cost savings.

How It Works

• The operating principle is straightforward yet highly effective:
• Floating Platform: The entire pump unit is mounted on a sturdy, buoyant pontoon that rests on the water surface.
• Vertical Drive Shaft: An above-water motor (or integrated submersible motor) drives a vertical shaft connected to the axial flow impeller.
• Axial Intake: The impeller draws water axially from beneath the pontoon, ensuring a steady supply even in shallow conditions.
• Vertical Discharge: Water is pushed upward through the outlet pipe, which can be connected to floating or land-based pipelines.
• Automatic Level Adjustment: As the water level fluctuates, the pontoon rises or falls accordingly, keeping the impeller at the optimal submerged depth for continuous, efficient operation.

This self-adjusting mechanism ensures consistent performance without manual intervention, regardless of seasonal changes, tidal variations, or drawdown.

Advantages & Features

1. Eliminates Hydraulic Construction
No need for cofferdams, dewatering, permanent foundations, or pump houses. The floating pump simply anchors in place, preserving the natural water body and reducing project complexity.

2. Cuts Engineering Costs by Over 60%
By removing the need for civil works, the floating pump dramatically lowers overall project costs compared to vertical, horizontal, or inclined fixed installations. This makes it the most economical choice for temporary or variable-level sites.

3. Automatic Water Level Adaptation
The pontoon ensures the pump inlet always stays at the correct submerged depth—no manual adjustment or complex control systems required. Perfect for reservoirs, rivers, and lakes with seasonal or tidal fluctuations.

4. High Flow, Low Head Performance
Leveraging mature axial flow pump technology, the floating pump delivers massive volumes of water at low heads (up to 15m), ideal for water transfer, irrigation, and drainage applications.

5. Rapid Deployment & Mobility
Pre-assembled and tested, the floating pump can be transported, launched, and operational within hours. It's easily relocated as project needs change—unlike fixed pumps.

6. Low Maintenance & High Reliability
Built with robust materials and proven axial flow components, the pump requires minimal maintenance and offers long service life even in demanding conditions.

7. Environmentally Friendly
No permanent structures mean minimal environmental impact. The floating pump can be removed without leaving a footprint, making it suitable for sensitive ecosystems.
