What Does Head Height Mean?
Head height is how high your pump can push water – the higher the lift, the lower the flow rate. The Pro 30000’s impressive 10-meter maximum head makes it perfect for tall waterfalls or high filter installations.
The table below shows the approximate flow rates at common head heights when the pump is running at maximum power (100%). Lowering the flow using the controller will reduce these rates proportionally, saving energy while matching your needs.

Safety Precautions
Electrical Safety: Ensure the power supply matches the pump's voltage (220-240V, 50/60Hz). Always use a Residual Current Device (RCD) to prevent electric shock.
Do not immerse the power plug in water or operate the pump with wet hands.
Keep the power plug in a dry, elevated location, away from water sources.
Disconnect the power supply before performing any maintenance or adjustments.
Regularly inspect the pump and power cord for damage. Do not use the pump if it is damaged.
Keep the pump out of reach of children and pets.
Controller Placement: If you have a controller/control box unless stated this is not waterproof. Install it indoors or in a weatherproof box away from rain and moisture.
Maintenance Tips
Routinely clean the prefilter and impeller to prevent blockages.
Inspect tubing, connections, and pump housing for signs of wear or damage.
During freezing weather, remove the pump from outdoor ponds and store indoors.
Ensure the pump remains fully submerged during operation to avoid overheating.
Installation Steps
Step 1: Pre-Installation
Ensure the pump is suitable for your pond, aquarium, or water feature size.
Confirm the placement area is flat, stable, and free from debris.
Prepare necessary tubing, clamps, or accessories for your setup.
Step 2: Positioning
Position the pump on a flat, stable surface at the bottom of your pond or water reservoir.
Ensure the prefilter is clean and securely attached to prevent debris from entering.
Use the suction cups to secure the pump in place and prevent unwanted movement.
Step 3: Connection
Securely attach tubing to the pump outlet. Use a hose clamp if needed to prevent leaks.
Route the tubing to your desired water feature (fountain, waterfall, filtration system).
Ensure tubing is free from kinks or bends to maintain smooth water flow.
Step 4: Testing
Connect the pump to a power supply and switch it on.
Observe water flow and adjust placement if necessary.
Check all connections for leaks and ensure quiet, efficient operation.
Troubleshooting
Low Water Flow
Check the intake for blockages or debris.
Inspect tubing for kinks or obstructions.
No Water Flow
Confirm power connection and that the pump is switched on.
Check for damage to the impeller or motor.
Excessive Noise
Ensure the pump is fully submerged and free of trapped air.
Inspect for loose components or debris in the impeller.
The Flow Pro series features powerful submersible pumps designed to circulate water efficiently in fish ponds, aquariums, and water features. Here's a simple explanation of how these pumps operate to enhance your aquatic environment.
Working Principles
Drawing Water
The pump is fully submerged in water and placed on a flat, stable surface.
Water enters the pump through the intake located at the base of the unit.
A built-in prefilter prevents debris from entering the pump, protecting the internal components.
Suction cups secure the pump in place during operation.
Moving Water
The pump uses a brushless, energy-efficient motor to power an impeller that rotates at high speed.
The impeller creates suction, drawing water through the intake and propelling it out through the outlet.
Water can be directed through tubing to fountains, waterfalls, or filtration systems.
The flow rate and lift height vary by model to accommodate different pond sizes and needs.
Supporting Aquatic Life
By circulating water, the pump helps oxygenate the pond or aquarium, promoting a healthy environment for fish and aquatic plants.
It reduces stagnant water and supports filtration systems to keep the water clean and clear.
Continuous water movement helps prevent algae growth and mosquito breeding.
Quiet operation ensures a peaceful environment for both aquatic life and human enjoyment.
Versatile Applications
When used with fountain nozzles, the pump creates decorative water spray patterns for ponds and gardens.
For aquariums or hydroponics, it ensures consistent water movement to maintain optimal conditions.
Can be integrated with filtration systems to enhance water quality.
Adaptable to various water features including cascades, streams, and ornamental displays.
Efficiency Features
Energy Conservation
Low power consumption design reduces electricity costs while maintaining optimal performance.
Energy-efficient motor provides reliable operation for continuous use.
Operational Reliability
Designed for continuous operation with minimal maintenance requirements.
Thermal protection prevents overheating during extended use.
Performance Optimization
Consistent flow rate ensures reliable water circulation.
Lift height capabilities allow for versatile installation options.
With their quiet, reliable operation and various flow rates to suit different needs, the Flow Pro series pumps are essential tools for maintaining vibrant and healthy aquatic environments, from small decorative features to large garden ponds.
