BLUE ECO 900W 4Flow (Variable speed / wattage)
- ENERGY EFFICIENT PUMPS
- FULLY VARIABLE FLOW
- SUITED FOR BOTH WET & DRY INSTALLATION
- 100% SEAWATER PROOF
- EXTERNAL CONTROLLER
- LATEST TECHNOLOGY (TRUE SINE WAVE)
- THE PUMP OF THE FUTURE!
The rotor is the heart of the driving force and needs to fulfill the highest of demands. The 8 pole rotor is built around the
tungsten or titanium shaft. This static and dynamic balanced rotor consists of 16 high quality neodymium super magnets. The
rotor is protected by a composite layer of aramid fiber reinforced carbon. Both ends have double shaft seal with smooth
bearings which sit in a resonance free silicon bedding. As well as making theses pumps capable of handling seawater it also
prevents vibrations which can be sensitive to some invertebrates and koi.
The 27 poles stator not only gives an equal propulsion, due to the True Sine Wave technique it also has
an unmatched torque.
The pump housing is made from blended ABS and PC (polycarbonate) that unifies the positive features of both
materials. Inside the housing the stator is fully cast in epoxy resin is protected by a strong layer of aramid fiber
The power module uses True Sine Wave technology for high reliability. Unlike brushless DC motors with square wave
technique, BLUE ECO pumps use True Sine Wave technology for the best features: high efficiency (90%), noise free
running, high torque, wide RPM range, CO2 reduction.
For pumps, the bearing system is the most important part for reliability and life span. Blue Eco pumps have a
diamond-hard bearing system of doped silicon carbide with or without the combination of the super strong
and durable tungsten. The use of these high quality materials are unique and exclusive for these pumps and
guarantee a long and trouble free operation.
The way BLUE ECO pumps are constructed prevents any internal leakage. The rotor rotates in the same
water that lubricates the bearings. With a unique rinse-system, different for both models, the water inside
will be continuously changed during operation.
The pump is completely waterproof confirming to class IP68 (up to 12 meters of water head).
The cables on the BLUE ECO have extra protection for maximum safety in case of damage. The outer mantle
is made of TPE and is fully saltwater proof. Due to this cable the pump can be fully submersible in (sea)water.
The controller is developed by Estrad BV and produced under supervision of the University of Shenzen,
China. This leading university is working close together with Europe’s biggest companies and universities in
The Blue Eco pump is the only pump in its class that has both the European CE certifications as well as the
German “TÜV Prüfungs and Test Certificate”. This guarantees extra quality and safety.
The University of Shenzen supplies the software for the controllers and every controller is individually
checked and certified. Every pump also undergoes an extensive test procedure and comes with its own
unique test certificate.
The parting line at 240 Watt shows, where the capacity of the 240 Watt pump stops. Above this parting line the values are only valid for the 320 Watt version.
The parting line at 500 Watt shows, where the capacity of the 500 Watt pump stops. Above this line the values are only valid for the 900 Watt version.
The parting line at 1500 Watt shows, where the capacity of the 1500 Watt pump stops. Above this line the values are only valid for the 2200 Watt version.
Since their introduction in 2010 it is hard to imagine the current pond World without Blue Eco pumps. Due to their durability and extreme low power consumption they have conquered a steady position in many ponds. All Blue Eco pumps are saltwater proof!
The 240/320 use the same pump but have different controllers. A 240 watt model is a 320 pump with a 240 watt controller. This controller is similar to the 320 watt controller but has a smaller True Sine Wave power module.
Connections 240/320: inlet 2½” male thr., outlet: 50/63mm. As of 2016, these models are provided with timer programs, cruise control and dry running protection.
These models are suited for the heavier work. Also this controller offers many extra options, like 5 timer programs that can control the
pump capacity and duration, the cruise control option and a full automatic protection against dry running. Even the possibility for a
second, external, control panel for remote control can be installed. Like the 240/320, the display shows the hour counter, power
consumption, amperage and RPM but also offers a vast number of messages to indicate problems, etc. A Blue Eco pump can pay for
itself within one year. Up to 50% less energy consumption, thus environmental friendly and good for CO2 reduction.
Connections: 500/900/1500/2200: inlet 2½” male thr., outlet: 2” male thr. Blue Eco 500/900/2200 with 4FLOW pump head: 3” Male
threaded (inlet and outlet).
Blue Eco pumps are very easy to install with flexible fittings. This simplifies maintenance
but also takes care of a resonance/vibration free and noise suppressing setup!
Attention! Use max. 1 extension cable per pump.
