Oase Aquarius Universal Classic Water Feature Pumps
Compact continuous-duty pumps for statuary, small fountains and indoor or outdoor water features
The Oase Aquarius Universal Classic range is designed for clean-water circulation where a compact, dependable pump is more useful than a large solids-handling filter pump. The six UK models cover gentle bubbling features, small ornaments, wall spouts and modest fountain displays from 440 to 3,000 litres per hour.
These pumps are valued for quiet operation, simple mechanical flow adjustment and their small footprint. The 600, 1000, 1500, 2000 and 3000 models may be installed submerged or dry in a flooded-suction arrangement; the 440 is intended for submerged operation. None is self-priming, so a dry installation must remain below the water level with the inlet continuously flooded.
Selecting the output: the maximum-flow figure is measured with little or no resistance. Select the model from the flow needed at the real working head after vertical lift, hose length, bends and fittings have been included.

Choosing the Classic 2000 or Classic 3000
The Classic 2000, UK part 36978, provides up to 2,000 litres per hour with a maximum head of 2 metres. It uses 25W and measures 125 x 80 x 75mm. This gives you additional output while retaining the compact body size associated with the smaller Classic models. Its hose connection accommodates 13, 19 or 25mm hose.
The Classic 3000, UK part 90222, is a larger pump measuring 245 x 130 x 135mm. It uses 40W and offers a maximum flow of 3,000 litres per hour and maximum head of 3.2 metres. Its connections also differ: the pressure outlet is G1 and the suction connection is G1½, with the specification listing 19, 25, 32 and 38mm hose sizes. Check the physical space and hose arrangement rather than treating it as a direct replacement with identical fittings.
Both versions have a 10-metre power cable and can be installed submerged or dry in accordance with their instructions. Dry installation means that the pump body is outside the water while its water circuit remains flooded. It does not mean the pump can draw water up through an empty inlet pipe or run without water. In the 3000 manual, Oase places the dry-installed pump below the water level.
The maximum head and maximum flow are separate endpoints on the pump curve. A Classic 3000 will not deliver 3,000 litres per hour at a height of 3.2 metres. For a raised ornament, select against the required flow at the actual lift and allow for the resistance of the complete hose route. Keep access to the intake, flow control and rotor housing clear when planning a concealed reservoir.
Oase lists a three-year guarantee plus a two-year extension available under its registration and guarantee conditions for these two models. Retain your proof of purchase and follow the registration requirements. For winter storage, use the instructions supplied with the exact pump rather than assuming that a statement for another Aquarius model applies.
Choosing the right size
For a small ornament, identify the inlet size, outlet height and the flow the ornament was designed to receive. The 440 is appropriate for the lightest duty. The 600 and 1000 offer more useful head for raised statuary, while the 1500 gives additional reserve for a larger feature or a longer circulation route.
Start by deciding what the display or circulation point must achieve. A small bubbling ornament needs much less water than a raised blade, a broad cascade or a tall fountain jet. Measure the vertical difference from the water surface to the highest outlet, then allow for friction. Narrow hose, long runs, sharp elbows, restrictive valves and undersized fittings all reduce the delivered flow.
If the result is critical, use the manufacturer’s performance curve rather than choosing only from the product name. It is usually better to keep the pipe bore generous and control a small amount of surplus flow than to make a marginal pump work at the edge of its capability. Use the model’s built-in flow regulator as described in its instructions, keep the water supply clear and never allow the pump to run without water.
Installation details that make a real difference
- Use clean water and fit an appropriate pre-screen where fibres, leaves or gravel could reach the impeller.
- For dry installation, keep the inlet permanently flooded and provide valves that allow safe removal for servicing.
- Support pipework independently so its weight is not carried by the pump connections.
- Use the built-in adjustment for final balancing after the system has been filled and purged of air.
Keep the pump accessible. Even a reliable water-feature pump needs its intake inspected and cleaned, particularly in shallow features where leaves, blanketweed and mineral deposits collect quickly. Isolate the electricity before touching the pump, cable or nozzle assembly, and use an outdoor supply with appropriate RCD protection.
How this range compares
Choose this Classic range for straightforward fixed-output duty. For electronically adjustable output, higher head or a professionally controlled display, compare the Aquarius Eco Premium range.

Frequently asked questions
Does maximum flow mean the amount I will receive?
No. It is a laboratory figure at minimal head. The installed flow falls as lift and pipe resistance increase.
Can I reduce the flow?
The pumps have mechanical flow regulation. Use the built-in control described in the instructions for your model. These are not electronically adjustable pumps; do not connect them to a dimmer or assume compatibility with an electronic speed controller.
Can the pump stay outdoors in winter?
Follow the winter-storage instructions for the exact model and protect the pump from freezing. Where the instructions require removal before frost, clean and store it as directed.
