The summary

What you receive: a Sicce Syncra Silent submersible pump with its pre-filter, suction cups and two pipe fittings.
Seven models: from 950 L/h up to a head height of 1.5 m to 5,000 L/h up to 3.8 m.
Submersible or in-line: the pump runs at the bottom of the tank or out of the water, connected via its inlet.
Power consumption: from 0.38 kWh per day for the 16 W model to 2.52 kWh for the 105 W model, running continuously.
For a small tank: below 1,000 L/h, the 600 L/h submersible pump is better proportioned.
What ships to you: a parcel weighing 0.5 to 1.94 kg depending on the model, sent by tracked delivery from France.

Adjustable submersible pump for gutters, grow beds and aquaponic water lift

Most soilless growing systems rely on continuous circulation: the nutrient solution leaves the reservoir, passes through the channels or grow beds, then returns to the reservoir by gravity. This submersible water pump handles that loop with a flow rate of 950 to 5,000 litres per hour depending on the model you choose. It sits on the bottom of your reservoir or your pond, and its flow can be adjusted without tools to suit the circuit. The same family of pumps equips the hydroponic channel kits for 10 to 80 plants, where the 1,350 L/h model supplies 40 plants and the 2,700 L/h model supplies 80.

⚙️ An adjustable synchronous motor

The motor is synchronous: its rotor, fitted with a magnet, turns at the frequency of the mains current, which ensures smooth running for a power output of 16 to 105 W depending on the model. The motor body is fully encased in resin, so you can leave the pump permanently submerged. A thermal cut-out stops it in the event of overheating, and the rotor shaft is ceramic on the most powerful models. On the front, a regulator mounted on the inlet pre-chamber lets you reduce the flow to spare a small circuit, without changing pump. Finally, double-height suction cups hold it to the bottom of the tank and limit the transmission of vibrations.

📏 Flow rate and delivery head

The flow rate stated for each model is measured with no head height, meaning the water leaves at the same level as the pump. As soon as the water has to rise to gutters or a grow bed, the flow rate drops, until it reaches zero at the maximum head height: 1.5 m for the 950 L/h model, 1.8 m for the 1,350 L/h model, 2 m for the 2,150 L/h model, 3 m for the 2,700 L/h model, 3.7 m for the 2,500 and 3,500 L/h models, and 3.8 m for the 5,000 L/h model. So choose a model whose maximum head height is comfortably above that of your setup, so that a useful flow rate remains at the top of the circuit. The 2,500 L/h model illustrates this trade-off: it delivers slightly less than the 2,700 L/h model while keeping pressure up to 3.7 m, which makes it suited to multi-level installations.

950 and 1,350 L/h, up to 1.8 m

These two models feed gutters or a grow bed set at a low height above the reservoir, at 16 and 23 W.

2,150 and 2,700 L/h, up to 3 m

These models serve long runs of gutters or a large grow bed, at 32 and 45 W.

2,500 and 3,500 L/h, up to 3.7 m

These models serve tall installations, on shelves or in tiers, where the water has to climb a large height difference. They draw 65 and 80 W.

5,000 L/h, up to 3.8 m

This model offers the highest flow rate in the range, for a large pond or several circuits fed from the same reservoir. It draws 105 W.

For a small tank, the 600 L/h pump

If your system fits in a tank of a few tens of litres, an ebb-and-flow table or a hydroponic pot, the 600 L/h submersible water pump is better proportioned than this one. It uses 6.5 W, pushes water up to 0.8 m and is adjusted in the same way on the front. You therefore keep a gentle circulation where a flow of nearly 1,000 L/h or more would needlessly agitate the solution and cost more in electricity.

Keep the intake submerged, even when fitted in line

The impeller needs water to turn without damage, even when fitted out of the water: a pump running dry deteriorates quickly. Always keep the level in your reservoir above the inlet and do not use the pump in water above 35 °C. Plug it into a socket protected by a residual current device of 30 mA or less, and leave the cable with a loop lower than the socket, so that water running along the cable drips onto the floor instead of reaching the socket.

🐟 Water circulation in aquaponics

In aquaponics, the pump circulates water from the fish pond to the grow beds, where nitrifying bacteria convert the ammonia from fish waste into nitrates your plants can absorb. A common rule of thumb is to pass at least once an hour the entire volume of the pond through the circuit. For a 1,000-litre pond with beds sitting 1 m higher, the 1,350 L/h model works close to its limit, since its flow rate falls sharply at that height, whereas the 2,700 L/h model keeps a comfortable margin. Ideally, place the pump in a calm area of the pond or in a sump, with its pre-filter fitted so that it does not draw in waste or fry. The guide to building your aquaponic system covers this sizing step by step.

🔧 Inline fitting and maintenance

For an out-of-water installation, the pump is placed in line, below the level of the reservoir, so that the water reaches the inlet by itself. Remove the flow regulator, screw one fitting onto the inlet and another onto the outlet, then push the two pipes on. The 2,500, 3,500 and 5,000 L/h models accept a 25 to 32 mm pipe on the inlet, wider than on the outlet, which reduces pressure losses. For maintenance, unplug the pump, take out the pre-filter and the pre-chamber, then rinse the rotor in clean water, checking the condition of the O-ring. Regular rinsing, more often if the water carries a lot of particles, preserves the original flow rate.

What flow rate, and at what height?

Seven pumps from the same family, set apart by the volume they move and the height to which they send the water.

More flow rate, or more head height? The volume to be moved and the height to be cleared are enough to tell the seven models apart.
