Plank 3.7 Mixing Pump Upgrade (BETA)

Building on the refinements introduced in v3.6, the new Plank v3.7 Flow Assembly continues our pursuit of perfecting the micro-feeding process. This version introduces subtle, yet important engineering updates that make the Plank smoother, cleaner, and more consistent than ever, while maintaining full backward compatibility with all previous models equipped with a Sicce pump.

Key Improvements

Optimized Hydration Flow
The v3.7 introduces a redesigned internal flow path, created in collaboration with Sicce engineers, which enhances laminar flow within the mixing chamber. Transitioning from a variable to a fixed flow rate removes guesswork in tuning and ensures optimal agitation for Reef Jerky’s soak process. This more consistent, smooth circulation reduces maintenance needs, cuts down waste, and maintains a cleaner feeding chamber for a longer period between cycles.

Built Stronger for Continuous Use
We expanded the internal surface area for improved structural strength and extended durability under continuous operation. The new assembly features reinforced components and tighter tolerances for dependable long-term performance.

Now Available (for Beta testing)
The v3.7 assembly is in limited beta now, available for early adopters to test and give feedback before the full release. It works with all existing Planks using Sicce pumps.

September 2026 Update 3.71

The flow geometry remains unchanged, but the assembly now fits entirely inside the feeding tube. The power cord remains clamped to the platform to secure the pump assembly, while the pump can be lifted out from the top for complete removal and cleaning without loosening the cord. This makes routine service significantly faster and easier.
