Sicce Suprema 3700 - 3700L/hr Submersible Pump for Reservoirs & Ponds
Best for: growers needing a reliable, high-flow submersible pump for larger reservoirs, dosing systems or garden ponds.
Our thoughts
Sicce built its name on pond and aquarium pumps before hydro growers caught on, and that engineering pedigree shows in how these run - quietly and continuously without fuss. Moves 3700 litres of water an hour, and it just gets on with the job.
The Sicce Suprema 3700 is a submersible pump from the Italian manufacturer Sicce, built for continuous duty in ponds, aquariums and hydroponic reservoirs alike. It moves 3700 litres of water per hour, making it well suited to larger recirculating systems, reservoir mixing, or feeding a manifold across multiple grow sites rather than a single small pot.
How it compares
It sits above entry-level submersible pumps on build quality.
- vs budget submersible pumps (Hailea): Sicce pumps are built to a higher quality tier with a strong reputation for longevity under 24/7 running, at a higher price point than entry-level Hailea units
- vs EcoPlus submersibles: a similar flow-rate class, but Sicce brings pond and aquarium engineering pedigree rather than a hydro-specific brand background
- vs smaller in-line pumps: the 3700 l/hr flow rate suits bigger reservoirs and multi-system feeds, not a small single-plant setup
In plain terms: reliable performance at a sensible price for anyone who needs real flow rate and doesn't want to think about their pump again.
Usage guidance
Placement
Fully submerge the pump in the reservoir or sump, keeping the intake clear of debris.
Plumbing
Connect the outlet to a feed line or manifold sized appropriately for the pump's flow rate.
Running
Designed for continuous 24/7 operation in recirculating systems, not just intermittent bursts.
Maintenance
Periodically clean the intake strainer to keep the flow rate consistent over time.

Our take
Reliable performance at a sensible price. Sicce's pond and aquarium background means these pumps are built to run day in, day out without drama, and 3700 litres an hour is plenty for most reservoir and dosing setups.
Gets the job done properly. Worth picking up if you need a pump you won't have to think about again once it's in.
