The WATER MASTER 800 L/H Water Pump is a compact submersible pump for indoor growing that delivers a flow rate of 800 L/h with low energy consumption. Ideal for medium-sized reservoirs, micro-drip irrigation, and small irrigation loops, it facilitates precise and consistent watering of indoor plants .

The WATER MASTER 800 L/H Water Pump is designed to move water from the tank to the main pipe with a uniform and quiet flow. The electrical unit operates at 230 V and 50 Hz , with an approximate power consumption of 22 W , sufficient for short and medium-sized lines in cabinets, tables, or compact workbenches.
The fully submersible design reduces noise and suction losses, while the intake grid helps contain coarse particles that could affect drippers.
The nominal flow rate of 800 liters per hour allows nutrients to be kept in motion, prevents settling, and improves mineral availability in the root zone.
Its compact size, base with suction cups for firm anchoring and quick maintenance (simple opening, rinsing of the impeller and closing) make this pump a reliable resource for daily routines.
Reference useful lift around 1–1.2 m , sufficient to overcome small differences in level between tank and table, fine mesh filters or compact distributors.
Easy integration with 16mm irrigation accessories , timers and valves, achieving an organized, scalable and efficient irrigation system within the grow room.
In indoor growing, consistent flow defines uniformity and vigor. The WATER MASTER 800 L/H water pump provides stable pressure for irrigation tables, return trays, and small manifolds, maintaining a homogeneous nutrient mix in the reservoir and ensuring even distribution to each pot. It's an excellent choice for growth and maintenance phases in setups where precise control of water delivery is crucial.
It is used to pump and recirculate water from the reservoir to drippers, diffusers, or a lightweight irrigation lance; it is also used to agitate nutrient solution, prevent sedimentation, and facilitate transfers between containers. The balance between a flow rate of 800 L/h and moderate energy consumption allows for extended sessions with reduced electrical impact, ideal for frequent and precise watering schedules.
Integration with standard irrigation accessories is straightforward: 16 mm irrigation tubing, reducers, distributors, low/medium flow pressure-compensating drippers , in-line filters, and non-return valves. With timers, irrigation windows can be staggered and times adjusted according to variety or phenological stage. Suction cup anchoring limits movement at the bottom of the tank when starting or stopping cycles, providing overall stability to the irrigation system .
The WATER MASTER 800 L/H Water Pump offers a very attractive cost-performance ratio for compact and medium-sized projects: 800 L/h delivery, consumption close to 22 W , functional lift of around 1–1.2 m and submersible mounting that reduces the need for additional accessories.
