Type of Use
Approx. Pond / Feature Volume
Typical Setup
General Circulation / Oxygenation
6 000 – 14 000 litres (≈ 1 300 – 3 100 gallons)
Large garden or koi ponds; adjust speed (50–100 %) for strong, efficient water movement
Filtration / Water Cleaning
Up to 12 000 litres (≈ 2 640 gallons)
Powers medium‑to‑large filtration systems or pressurised filters; run at higher speeds for full turnover
Waterfalls / Streams / Fountains
Effective up to 5–6 m lift
Produces a smooth, adjustable flow—ideal for medium to tall waterfalls and decorative displays
Smaller Ponds (< 3 000 litres)
Suitable only at low speed (30–40 %)
Lower flow settings maintain gentle circulation without excess turbulence
Tip: To estimate pond volume (L), multiply average length (m) × width (m) × depth (m) × 1 000. For example, 3 m × 2 m × 0.8 m ≈ 4 800 L.

What Does Head Height Mean?
Head Height is simply how high your pump can push water – and the higher it goes, the less flow you get. Check the table to see exactly how the Vari‑Flow Pro 12000 performs at different lift heights when running at full power, so you can match the right setting to your pond or water feature.
The table below shows the approximate flow rates you can expect at common head heights when operating at maximum output (100%). If you use a lower speed on the controller, the flow rates will reduce proportionally, helping you save energy and tailor performance to the season.

Follow this guide to safely and efficiently install your Flow Pro series pump. Proper installation and maintenance will ensure optimal performance and a long lifespan for your pump.
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.

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
