A MODERN PUMPING PLANT 
Section of the New Electric .Pumping Plant at the New York 
Aquarium 
The four pumps on the right are for the circulation of refrigerated 
fresh water in summer and for emergency use when water pressure is 
low in the City mains. The four on the left, pump stored sea water 
to the glass-fronted tanks and harbor water to the large floor pools. 
The vacuum pumps in the rear return the exhaust steam from the 
heating system to boilers for reheating. Just above them is the ex¬ 
haust return tank. All of the above pumps are in dupli?ate as a safe¬ 
guard against breakdown. Beyond these pumps are located the new 
low-pressure boilers. 
Single pumps that are not shown here in the photograph are as 
ollows: Air compressor to aerate sea water tanks and aid in the clean¬ 
ing of filters. Vacuum pump to prime all pumps for easy starting. 
Thermostatic control pump to regulate the heat of the radiators in the 
building during the winter. Ammonia compressor for the refrigeration 
of fresh water in summer. Motor driven fan for the circulation of fresh 
air on main floor. Sump pump, a safeguard against flooding of pump 
room.
