Syncra Silent 2.0 Pump (568 GPH) - Sicce

The Syncra Silent 2.0 sits in a well-established line of submersible pumps from Sicce, an Italian manufacturer with a long track record in the aquarium industry. At 568 GPH and 35 watts, the 2.0 offers a strong flow-to-watt ratio and is sized appropriately for sump return duty on small-to-mid-size reef systems, as a feed pump for protein skimmers, or for driving low-pressure reactors. Its synchronous motor design, paired with high-quality magnets and an advanced rotor assembly, is what separates the Syncra Silent line from similarly priced competitors — the result is near-silent operation that most hobbyists will notice immediately in a quiet room.

The ceramic shaft and bearings are a meaningful spec at this price point. Ceramic resists corrosion in saltwater far better than stainless or standard metal alternatives, contributing to both longevity and reduced wear noise over time. Flow rate is adjustable, which gives you the flexibility to dial the pump back when running a reactor or skimmer that doesn't need full output. The pump accepts both 3/4" Female NPT fittings and 3/4"–1" hose barbs on inlet and outlet, making plumbing straightforward in most common setups.

The Syncra Silent 2.0 can be run fully submerged in a sump or configured for in-line use outside the water — useful when heat transfer into the system is a concern or when inline placement improves plumbing geometry. Rated at 2.82 psi, it has enough pressure to handle typical return runs with moderate head. At 4.84" x 3.35" x 4.13", it fits in most standard sump chambers without issue. Sicce covers the motor for five years with online registration and the impeller for six months, which is among the stronger warranties available in this pump category.
