INDUSTRIAL PUMPS FOR BIG AQUARIUMS: APPLICATIONS WITH FRESHWATER AND SEAWATER

 In Technical Support

APPLICATION: THE PUMPING SYSTEM OF BIG AQUARIUMS

The fish tanks of big aquariums allow the public to admire many fascinating underwater creatures. Through hundreds of windows the enchanted visitors look at the wide variety of plant and animal species which populate lakes, rivers and oceans of the planet.

Aquarium pumps

The invisible and complex pumping system of big aquariums permits the survival of aquatic species in freshwater and seawater inside the exhibition tanks. The circulation and filtration of the water is possible thanks to the pumps which direct the liquid through the filter before returning it to the tanks.

The pumping system must guarantee the quality of the water by maintaining its main chemical and physical properties in order to recreate the natural habitat of the aquatic flora and fauna.

The pumps used in these giant freshwater and saltwater aquariums must be corrosion resistant and able to pump large amounts of liquid. Moreover the pumps must be silent to avoid the risk of creating a stressful situation that could alter the normal fish behaviour.

 

SPECIFIC REQUIREMENTS FOR THIS APPLICATION: WHICH ARE THE BEST PUMPS FOR APPLICATIONS IN BIG AQUARIUMS PUMPING SYSTEMS?

Pumps made of thermoplastic materials are recommended for large systems pumping saltwater or freshwater.

The thermoplastic materials used in the manufacture of GemmeCotti pumps are solid and lightweight and they don’t absorb water. Certainly, the best material for the construction of saltwater pumps is polypropylene (PP), a thermoplastic polymer with a good thermal, mechanical and abrasive resistance.

The use of this anti corrosion material, instead of the installation of pumps in metallic materials, avoids the risk of dispersion of metallic particles, which could harm the health of the sea fauna.

WHICH IS THE BEST TYPE OF PUMP TO CHOOSE?

Centrifugal pumps are the best choice for freshwater and seawater aquariums.

A centrifugal pump is made of a movable part called the impeller that forces the liquid under pressure in a desired direction.

MAGNETIC DRIVE CENTRIFUGAL PUMPS

Centrifugal pumps can be designed with a particular system called magnetic drive.

Mag drive pumps have a sealless design that is particularly suitable to pump corrosive and dangerous liquids; the magnetic design together with the usage of anticorrosive thermoplastic materials, guarantees the high chemical resistance and the absence of leakage and emissions. Thanks to the total absence of emissions and leakage, the plant will always be clean; this feature coupled with the reduced maintenance required by GemmeCotti pumps, helps in keeping the plant efficient, secure and reliable.

The structure of magnetic drive pumps is really simple and requires very little maintenance with a consequent saving in terms of repairs and spare parts expenses during the pump life.

The use of mag drive centrifugal pumps in thermoplastic materials, such as GemmeCotti pumps series HTM PP/PVDF, is the best solution for working with fresh water and sea water. In particular, the smallest models of this series (HTM 4, HTM 6, HTM 10) are particularly recommended for the pumping system of big aquariums.
