Oase isn’t known for movement pumps, but for its external filters (wonderful filters, I would add. Check here for evidence) and beautiful aquarium systems. But here today we’re going to discover another peculiarity: their movement pumps, starting with the StreamMax Classic 5000.

OASE movement pumps are divided in two versions, Classic and Premium, and in three different power capacities, 2.000, 4.000 and 5.000 l/h. The Classic version, the one we have in our hands, differs from the others for the suckers in place of the magnet and for its fixed rate. The Premium version can be used through controller or app associated with EAC Acquarium Controller.
Oase StreamMax Classic 5000 – Technical characteristics
| Maximum rate | 5.000 l/h |
| Minimum rate | 3.600 l/h |
| Consumption | 10 watt |
| Dimensions | 120x68x78 mm |
| Price | 55 euro |
The pump is hinged through an adjustable mechanism that starts at the hooking base. The mechanism, that encircles the pump on the sides, allowes the pump to turn on the pin axis.
The pump isn’t electronically adjustable, but through a blue sector on both the sides of shell it adjust a deflector that widens the flow and decreases its power. In the pictures here below you can see the position of the blue deflector in the two positions.
The flow is generated by a two-blade propeller that guarantees a very smooth flow in the water. This featured, combined with the possibility to widen the flow, make these movement pumps perfect for both marine and fresh water aquariums.
Maintenance costs and flow rate per watt
It’s difficult to speak of any accessory for aquariums without considering the maintenance costs and the flow rate per watt, values that allow us to make the necessary comparisons with the other pumps on the market.
For the maintenance cost per year you consider the use of these pumps in two ways: a couple alternated every 6 hours for marine aquariums, a continuous use for fresh water aquariums. Obviously the cost it’s the same, except for the fact that you use two pumps instead of one in marine aquariums, although they work half the time.
10w x 24h x 365days / 1000 * 0,22 (energy cost) = 19,3 euro/year
All in all it’s a contained cost for the movement in your aquarium, a little bit more of a coffee… per month.
In order to do a ccomparison with other Stream pumps we can indicate as a parameter the flow rate per watt, a very easy calculation:
5.000 l/h / 10 watt = 500 l/h*watt
And similarly the flow rate per euro, in fact we obtain:
5.000 l/h / 55 euro = 91 l/h * euro
This pump has a contained cost, it’s adjustable in all the directions and it has the possibility to widen and narrow the flow. Quality signed by Oase.
