Choose the right pump for your water flow
These Water Master submersible pumps can feed a small irrigation circuit or recirculate water in a nutrient reservoir. Select one of six versions by flow rate. Power consumption and maximum pumping head vary by model.
Compare the six models
| Flow rate | Power | Max. head | Package (L × W × H) | Gross weight |
|---|---|---|---|---|
| 400 L/h | 5 W | 0.8 m | 7 × 7 × 10 cm | 0.2333 kg |
| 600 L/h | 8 W | 1 m | 11 × 9 × 8 cm | 0.5303 kg |
| 800 L/h | 16 W | 1.3 m | 12 × 10 × 8 cm | 0.4166 kg |
| 1 000 L/h | 22 W | 1.6 m | 12 × 11 × 11 cm | 0.5555 kg |
| 1 400 L/h | 28 W | 2 m | 12 × 13 × 11 cm | 0.8148 kg |
| 1 800 L/h | 40 W | 2.5 m | 12.5 × 14.5 × 11.5 cm | 1.054 kg |
Dimensions and gross weight are supplier logistics data for one unit. The stated flow rate is nominal; actual flow depends on pumping height and pressure losses in the system.
How to choose
Consider the vertical lift from water level to outlet, tubing length and number of outlets. Maximum head is a limit, not a promise of nominal flow at that height. Hortitec does not specify the outlet connection diameter in the supplied data, so check it before choosing tubing.
Installation and care
Place the pump submerged in the reservoir, connect the water circuit, then use a suitable 220–240 V / 50 Hz power supply. Clean the intake grille regularly to reduce clogging. Follow the instructions supplied with the device.
