Bomba de Diafragma 680 L/h Water Master

In most grow rooms, the irrigation pump has traditionally been a submersible centrifugal unit — fine for hand watering or flood-and-drain, but as soon as you connect it to a drip system with any back-pressure, flow becomes uneven. The usual fix is to oversize the pump, and even then results are inconsistent across emitters.

The Water Master 680 l/h is a three-chamber diaphragm pump — a positive displacement design. Instead of relying on rotational inertia to move water, it actively pushes fluid through each chamber in alternating cycles. The result is a consistent, stable pressure with a maximum working pressure of 1.2 MPa, regardless of how many drip emitters are open or how long the circuit runs. Every point in the system gets exactly the same.

Beyond its hydraulic performance, the pump's compact footprint stands out: at just 23.5 x 13 x 12 cm and 1.85 kg, it fits into any corner of the grow without taking up meaningful space. The self-priming capability up to 3 metres means it can be installed outside and above the reservoir — no submersion needed.

It handles clear water and nutrient solutions with a pH between 4 and 10, runs dry without damage, and includes built-in thermal protection for intensive use. At ≤70 dB with anti-vibration rubber feet, it's quiet and unobtrusive in any growing environment.
