Performance at a glance
With a 4 mm hose and an 11V supply, this pump provides a range of flow rates depending on the head height. Understanding these figures can help you plan dosing with greater confidence:
- 0.9 m head: up to 110 L/h
- 1.4 m head: up to 80 L/h
- 1.8 m head: up to 58 L/h
- Max head (Hmax): 3.6 m
In everyday use, you may notice a steady, dependable dosing rhythm that blends with your routine. The pump’s compact footprint makes it a natural fit behind shelving, inside a cabinet, or alongside other dosing gear, so it remains largely out of sight while still delivering reliable performance.
Tips for best results
To get the most from your replacement pump, verify compatibility with your Osmolator version, route hoses to avoid backpressure, and inspect fittings periodically for tight seals. The unit is designed to drop into the Osmolator footprint, helping you maintain dosing routines with minimal downtime.
Whether you’re upgrading an aging component, replacing a failed pump, or retrofitting a new Osmolator setup, this Tunze pump offers a compact, efficient option that aligns with typical reef-keeping needs.
