Don’t have enough flow? Well, the Tunze Turbelle Masterstream would do that job…… that is if you had a HUGE aquarium, Koi pond, or were running a Zoo or a Fish breeding operation. This new class of pumps from Tunze offers a high-capacity propeller designed for maximum efficiency, wide flow, and economical energy consumption. The new electronic Tunze PM motor operates at extra low voltage, and the pumps are quieter than ever, even at full force.

The smallest Tunze Masterstream model, the Turbelle Masterstream 6508, pumps out between 5283 to 21,133 gallons per hour, while the largest one (6515) shoots out between 13,208 and 39,528 GPH!!!!!!

ECO ENERGETIC
A small sample calculation using Turbelle® masterstream 6515 (150 m³/h – 280 W) reveals that energy efficient water movement results in enormous cost effectiveness:
Tank volume: 60 m³, flow selection by centrifugal pump (32 m³/h – 2,200 W). At an annual operating time of 8,760 hours and a kilowatt price of EUR 0.20 this results in a cost saving of EUR 3,364 per annum !

CONTROLLABLE PERFORMANCE
The Turbelle® masterstream are electronically speed-controlled pumps operating on safety extra-low voltage of 12 V to 24 V. They can be used ideally for water circulation, wave action or wave-and-tide simulations. The models 6512 and 6515 come with Multicontroller 7096.

A 12 V VERSION FOR SWIMMING POOLS
Model 6512 in 12 V technology and a flow rate of 110,000 l/h (29,058.9 USgal./h) has been designed especially for swimming pools or large aquariums.

100 PER CENT CORROSION-RESISTANT
All parts of the pumps are made of sustainable active microbicidal (SAM) polymers and polyoxymethylenes (POM); the motor axle is made of titanium alloy; the motor and the electronics are cast in polyurethane (PU) resin.

NO EXTERNAL CONTROL
The pump control is integrated completely in the motor block ensuring a low-maintenance operation with high efficiency and ideal water cooling. All Turbelle® masterstream pumps only require one external power supply unit or safety connector with a corresponding direct current source (battery, solar cell, et cetera).

NO PROBLEM IN CASE OF POWER FAILURE
Fitted with Safety Connector 6515.50, Turbelle® masterstream can be operated on every 11 V to 24 V direct-current source (battery, solar cell). The safety connector permits normal operation with the TUNZE® power supply unit, but in case of a power failure it will automatically switch over to a car battery or a direct-current source.
