Special application for Turbelle electronic

Special application for Turbelle electronic

Enquiry from Mr. Degen / Slovenia

I wish to install a 40 Litre sea aquarium on a boat. Th accumulator produces a voltage of 12 V , therefore I need a pump which operates at this voltage and whose rotation speed is variable. I such a pump available ?

Answer

We can offer you an electronic aquarium pump type 7200/2. For operation at 12 V DC it will be necessary that we provide the pump with a driver in our factory – ask our company for this special equipment. Connection is possible to direct current ( with a 1.5 A fuse). For an aquarium of this size we recommend to likewise replace impeller and impeller case by articles Nos. 233.12 and 1201.13.

Question

Many thanks for your information about the products which interest me. In a catalogue I have been able to see here in Slovenia the pump 7200/2 and driver 7240.25. They comply perfectly with my requirements. However, I still need additional information about the impeller and the impeller case. You write that you recommend "replacing the impeller and impeller case by articles Nos. 233.12 and 1201.13". I need a system which will allow me to keep living sea fishes in a basin (50 cm long x 17 cm wide x 45 cm deep), which I will fit in the fishing boat. The current of fresh water must flow in one direction (from the sea into the basin and out through a hole at the other end) and not circulate. Due to the wave motion it is possible that air is taken up for short periods – what consequences could this have for the pump ?

Answer

Our recommendations are quite adequate for your desired equipment and will apply in any case. No problems need be expected if air enters the pump. But it is important that the rotor must invariably be wet due to running on aqueous filter bearings. Another note: this pump is not a regenerative pump and must therefore always be located below the water surface during operation.
