About OASE AquaMax Eco Premium 21000
The OASE AquaMax Eco Premium 21000 is a filter / watercourse pump intended for large pond and filtration installations. OASE publishes a maximum flow of 21,000 l/h (350 l/min) and a maximum head of 6.00 m for this exact model. The unit offers electronic/digital adjustment and is compatible with OASE Control systems; it also supports an optional external Eco Control and integration with OASE Garden Controller Cloud systems. Built-in functions stated by the manufacturer include Seasonal Flow Control (SFC), which can reduce flow by up to 50% in response to temperature, and Environmental Function Control (EFC) to protect the pump against dry running and blockages. The pump accepts G 2 pressure-side and suction-side connections and can accept hose connections in 25 / 32 / 38 / 50 mm (listed equivalently as 1", 1 1/4", 1 1/2", 2"). It may be installed submerged or dry (for a pump chamber), and the manufacturer lists a 10.00 m power cable. Other manufacturer-stated technical details include a 1000 cm² filter intake surface, a permitted coarse debris displacement of 11 mm, overall dimensions of 340 × 275 × 160 mm (L × W × H) and a net weight of 6.9 kg. OASE also displays a guarantee of "3 + 2 Years" for this model. OASE does not list an integrated UVC lamp for this pump on the product page, and OASE does not publish a single pump-only pond-capacity figure on the pump product page. The manufacturer's Clear Water Guarantee tables do associate this pump as the recommended pump for several qualifying filter+UVC systems; those system volumes are system-level statements and are not pump-only capacities.
Best for
Filter-fed ponds and watercourse installations; recommended by OASE as the pump for several large BioTec filter+UVC qualifying systems (system-level recommendations).
Things to consider
OASE publishes conflicting power figures for this exact model on its product pages: the product description text states a power consumption of 175 W while the specification table on the same page lists "Power consumption 20–180 W." Because the manufacturer statements conflict and no single definitive wattage is given in the materials reviewed, the powerWatts field is left null. OASE does not publish a pump-only pond-capacity (litres) on the pump product page; volumes shown in the Clear Water Guarantee refer to complete filter+UVC systems that list this pump as recommended. The product page reviewed does not state an IP (protection) rating or a separate operating-pressure value.
