This pump with compact 12V water is the ideal solution for replacing the pump Tunze 5000.020 of your osmolator. Thanks to its brushless design and its ceramic axis, it offers a much higher reliability than conventional lifting pumps for total peace of mind.
Let it be to replace the pump of your osmolator Tunze 3155 or to create a custom water transfer system, this pump 12V CC stands out for its robustness. Unlike basic models, it uses a permanent magnetic rotor "Brushless" (without brooms), ensuring an exceptional longevity estimated at 20,000 hours of operations.
The use of high performance ceramic shaft Not only reduces friction (and therefore heating), but also ensures perfect compatibility with fresh water like sea water. Its static sealing system removes traditional dynamic joints, frequent sources of breakdowns on low voltage pumps.
Although perfect to replace the reference Tunze 5000.020Its robust design allows it to transport various fluids (alkaline solutions, osmosis water, seawater preparations) at temperatures up to 75°C.

The RecifArt Council: When installing a pump Tunze, make sure to respect polarity to ensure the optimal direction of rotation. This pump is submersible, but can also be used out of water if the circuit is laden (severity initiation).
Yes, this 12V pump is an ideal alternative for replacing the pump Tunze 5000.020 used on brand osmolators. It can also be used for any other 12V water transfer or supplementation application.
The pump is equipped with a permanent magnetic rotor Brushless (without brooms), which reduces mechanical friction. This ensures quiet operation and an exceptional service life of up to 20,000 hours.
Absolutely. It incorporates a high performance ceramic axis, essential for prolonged use in aquatic environments. In addition, sealing is ensured by static sealing (insulated winding), eliminating any risk of electrical or hydraulic leakage at engine level.
Despite its compact size, this pump offers a maximum flow rate of 240 L/h and a discharge height (water column) up to 3 meters, which is perfect for evaporation compensation, even if your water supply is located in the furniture of theaquarium.
Yes, it is designed to operate in a temperature range from 0 to 75°C and supports various fluids, ensuring maximum robustness even in the case of intensive operating conditions.
