Energy-Efficient Pond Pump
The OASE AquaMax Eco Premium 21000 is designed to provide high water flow while maintaining efficient operation.
Its electronically adjustable performance allows the pump output to be adapted to the requirements of the pond and filtration system. Power consumption ranges from 20 to 180 W.
This flexibility is particularly useful where maximum pump performance is not required continuously.
Seasonal Flow Control
The integrated Seasonal Flow Control (SFC) function allows the pump to respond to seasonal changes when the function is activated.
SFC adjusts pump performance according to water temperature. Therefore, the pump can reduce unnecessary energy consumption during periods when full output is not required.
The SFC function can be switched on or off depending on the requirements of the installation.
OASE Control Compatible
The OASE AquaMax Eco Premium 21000 features an integrated OASE Control connection.
This allows the pump to be incorporated into a compatible OASE Control system for convenient electronic monitoring and adjustment.
The pump can also be operated using the optional OASE Eco Control controller.
Environmental Function Control
OASE Environmental Function Control (EFC) provides additional operating protection.
The system helps protect the pump against dry running and blockages. This is particularly useful for a pond pump designed for reliable continuous operation.
Handles Debris up to 11 mm
The AquaMax Eco Premium 21000 can transport plant debris or fish waste particles up to 11 mm.
In addition, the pump has a large 1,000 cm² filter intake surface. This helps provide reliable water intake when the pump is installed submerged.
Submerged or Dry Installation
The OASE AquaMax Eco Premium 21000 pond pump offers flexible installation options.
It can operate submerged in the pond or as a dry-installed pump. Dry installation can be particularly useful in dedicated pump chambers and filtration areas.
The pump uses G 2 suction and pressure connections. Hose connection options include 25, 32, 38 and 50 mm.

OASE AquaMax Eco Premium 21000 for Koi Ponds
Reliable water circulation is an important part of an effective koi pond filtration system.
The AquaMax Eco Premium 21000 provides a maximum flow of 21,000 l/h. However, the actual flow achieved through a pond system will depend on the installation.
Pipe diameter, pipe length, fittings, valves, filtration equipment and total head height can all reduce the delivered flow.
Therefore, the pump should always be selected according to the requirements of the complete pond and filtration system.
Why Choose the OASE AquaMax Eco Premium 21000?
The OASE AquaMax Eco Premium 21000 combines high water flow with efficient motor technology and electronic control.
Its 21,000 l/h maximum flow, 6 metre maximum head and ability to handle debris up to 11 mm make it a versatile choice for demanding pond installations.
OASE Control compatibility also provides additional options for controlling and monitoring the pump as part of a compatible OASE system.
