Oase Aquarius Eco Expert Fountain Pumps
Oase Aquarius Eco Expert Fountain Pumps
Serious fountain pumps for large jets, water features and professional displays
The Oase Aquarius Eco Expert range sits a long way above an ordinary decorative pond pump. These are high-performance fountain pumps for installations where the finished water pattern needs real height, strong flow and dependable control. They are the sort of pumps we look at for substantial formal fountains, architectural water features, large water blades and commercial displays where an under-sized pump would be an expensive disappointment.
The range on this page runs from the specialist Aquarius Eco Expert 20000 12V through the mains-powered 22000, 28000, 36000 and 44000. The mains models provide maximum flows from 22,000 to 44,000 litres per hour and maximum heads of roughly 9.6 to 10.5 metres, so the choice is about much more than simply moving a lot of water.
What makes the Eco Expert range different?
Oase builds this range around powerful, electronically controllable motor technology. Compatible pumps can be adjusted using the Oase Eco Pump Control or incorporated into a wider Oase Control installation through equipment such as the Garden Controller EGC Cloud and InScenio FM-Master EGC Cloud. That is useful when the display needs commissioning at a particular height, seasonal adjustment or coordination with lighting and other effects.
The integrated Dynamic Function Control can create changing water patterns rather than one fixed jet. Oase also uses a robust stainless steel intake basket capable of passing coarse particles up to 4 mm, supplies an adapter set for compatible 1-inch and 1½-inch Oase fountain attachments, and rates the range for submerged or dry installation. Frost protection down to -20°C is helpful, although the complete installation—especially exposed pipework and nozzles—still needs a sensible winter plan.
Our honest advice before you spend this much on a pump
At this price level we do not recommend choosing from the model number alone. A 44,000 litre-per-hour pump will not deliver 44,000 litres at a ten-metre lift, because maximum flow and maximum head are opposite ends of the performance curve. We want to know the nozzle, required jet height, vertical lift, pipe length, pipe diameter and number of fittings. With those details, we can help narrow the range properly and avoid paying for performance that the pipework immediately wastes.
Choosing the Right Aquarius Eco Expert Model
Aquarius Eco Expert 20000 12V
The 12V model is the specialist choice where the installation calls for low-voltage equipment, including certain swimming-pond, public or accessible water-feature designs. It offers up to 20,000 litres per hour and a maximum head of 6.6 metres, but it should be selected as part of the complete electrical and hydraulic design rather than treated as a direct substitute for a mains model.
Aquarius Eco Expert 22000 and 28000
The 22000 reaches up to 22,000 litres per hour with a 9.6 metre maximum head, while the 28000 reaches up to 28,000 litres per hour with a 10 metre maximum head. These are often the sensible starting point for a substantial single jet or medium commercial display where controllability matters as much as outright size.
Aquarius Eco Expert 36000 and 44000
The 36000 and 44000 are for the largest duties in this family. Oase quotes maximum flows of 36,000 and 44,000 litres per hour, with maximum heads of 10.2 and 10.5 metres. Their extra capacity is valuable for broad or tall displays, but only when the nozzle and pipework can use it.
Control is part of the system, not an afterthought
For a fixed feature, the direct Eco Pump Control gives a straightforward way to adjust output and read operating information. For a coordinated garden or commercial installation, Oase Control equipment can bring compatible pumps, switching and lighting into one system. We will always check which control route suits the exact pump rather than assuming every controller provides the same functions.
Why buy an Eco Expert pump from That Pond Guy?
We are an independent pond company, so you are not dealing with a call centre reading the same maximum-flow figure shown on the box. We can talk through the feature, challenge an unrealistic pipe size and help identify the fittings, controller or nozzle that are easy to overlook. With a pump in this price bracket, a short conversation before ordering is usually time well spent.

Oase Aquarius Eco Expert FAQs
What is the difference between Aquarius Eco Expert and Aquarius Universal Premium?
Eco Expert is the high-output, electronically controllable range for demanding fountains and dynamic displays. Universal Premium is a quieter, mechanically adjustable range for clear-water features and more moderate duties.
Which Aquarius Eco Expert models are on this page?
The listed pump models are the 20000 12V, 22000, 28000, 36000 and 44000, alongside compatible Oase control equipment.
What are the maximum flows of the mains-powered models?
Oase quotes 22,000, 28,000, 36,000 and 44,000 litres per hour respectively. Those figures are at the low-head end of each performance curve.
Can Aquarius Eco Expert pumps create changing fountain patterns?
Yes. The Dynamic Function Control feature can create varying water patterns, and compatible control equipment provides further adjustment options.
Can Aquarius Eco Expert pumps be dry installed?
Oase lists the range for submerged or dry installation. A dry installation still needs the correct flooded suction, ventilation, pipework and access.
Which model is suitable where 12V equipment is required?
The Aquarius Eco Expert 20000 12V is the low-voltage model in this category. Suitability must still be checked against the complete installation and applicable rules.
Are fountain nozzles included?
Check the exact product listing. Oase supplies an adapter set for compatible fountain attachments, but the display nozzle or attachment may be a separate item.
Will the pump pass debris?
Oase states that the robust stainless steel intake basket can pass coarse particles up to 4 mm. It remains a fountain pump, so it should not be treated like a general solids-handling filter pump.
What information should I send for a pump recommendation?
Send the required water pattern and height, nozzle model, vertical lift, pipe length, internal pipe diameter, fittings and whether you need 12V or Oase Control.
Why is the flow at my feature lower than the number on the pump?
The headline flow is measured at very little resistance. Height, pipe length, bends, valves and the nozzle all reduce the flow that reaches the outlet.
Should I deliberately buy a much larger pump?
For Oase Aquarius Eco Expert Fountain Pumps, a little adjustment margin is useful, but excessive oversizing wastes energy and can make the display difficult to control. We size from the pump curve and the finished pipe run.
Does pipe diameter really make much difference?
Yes. Undersized pipe can throw away a surprising amount of a pump’s performance, especially on longer runs or higher-flow installations.
Can I restrict the flow with a valve?
A valve can trim some installations, but an approved variable-speed or electronic control is usually the neater option when the pump supports it.
Can the pump be installed dry?
Only models explicitly approved for dry installation should be used that way, and the suction arrangement must remain flooded and airtight.
What should I clean on a water-feature pump?
Keep the intake, rotor area and any pre-filter clear. A gradual loss of display height is often the first sign that the intake or pipework needs attention.
Can a fountain pump run all winter?
Follow the model instructions. Some Oase ranges are frost-resistant when left submerged, but exposed pipework, nozzles and shallow features still need sensible winter planning.
Can you help me choose between two models?
Yes. Send us the required display, lift height, pipe length and pipe size. Those details are far more useful than pond volume alone.
