This “low voltage” micro pump has been designed to transfer water intended for the maintenance of the aquarium from the transport canister to the aquarium itself due to its small size and its high prevalence (up to 2 mt). The slowness of the water flowing is designed to not replace the chemical values of aquarium water which would cause damage to fish. Technical sheet Voltage: 230 Volt Frequency: 50 Hz Transfer: 7.5 Volt/10 Watts Pump Power: 4.5 Watts Range: 90 Litres / h Prevalence: 2 m Maximum working depth: 0.6 cm Measurements: 4.5 x 2.5 x 3.5 cm
