Designed by German engineers, the Oase AquaMax eco expert 20000 / 12V boasts an extremely high flow rate with comparably low energy consumption for maximum efficiency.

It's perfect for supplying large volumes of water to filters and watercourses with a flow rate of up to 19300lph, a maximum head height of 4.6m with power consumption ranging from 30 - 260 Watts. What's more, this 12V version is also safe to use in swimming ponds.

The pump itself uses a robust, stainless steel cage to displace coarse debris up to 11mm in diameter before supplying the water to a large filter system or watercourse.

The flow rate will be adjusted automatically by the seasonal control function (SFC) depending on the temperature of the water, providing energy savings of up to 30%. The flow rate can also be adjusted electronically using the Oase Eco Control Panel or using the app once connected to the Oase InScenio EGC Controller Cloud.

The pump can be installed either submerged or dry-mounted and the patented frost protection enables the pump to resist damage down to temperatures of -20°C.
