Antwerp Zoo, Belgium

First project:


Aeration of the ditch in the outdoor Siberian tiger enclosure.


Executing companies:

Zoo Antwerp, Belgium

Marine Motors & Pumps (nv)



The problem:


The intense algae growth in the ditch in the outdoor Siberian tiger enclosure should be stemmed through aeration.


Our solution:


The first attempt to supply oxygen using a fountain failed because the fountain attracted the tiger's attention with the result that he climbed onto the pump and destroyed the hose. A type 15-TRN submersible aerator now provides a continuous supply of oxygen. The hose for the air supply is out of the tiger's reach.


Second project:


Running a waterfall in the park grounds of the zoo.


Executing company:

Zoo Antwerp, Belgium

Marine Motors & Pumps (nv)


The problem:


Twigs and leaves result in the clogging of standard pumps.


Our solution:


After many problems with pumps from other manufacturers a decision was made to use a 80C21.5 with a built-in cutting mechanism.

Solid material such as twigs and leaves are chopped up and pumped along with the water. This ensures problem-free operation.

In the event of abrasive and corrosive utilization, stronger wear and tear will take place naturally in certain components. With regards to the above application wear and tear can take place mainly in impeller, agitator, suction plate, shaft sleeve, oil ring, mechanical seal, pump casing, strainer, motor casing and discharge coupling. Depending on the working conditions the lifetime of those parts might vary significantly and can be shorter than the legal warranty period.
In this regard, please pay attention to our general terms and conditions that we also send to you by mail on request.
