HVAC Chemical Feed Pumps
They may be small, but they play a big role in maintaining your cooling tower system.
By Grant Tolentino
uick to task, incredibly effective and costefficient to maintain and operate, cooling
towers have long been the alpha component
Cooling towers dynamically remove heat from
attempered interior spaces via the managed recirculation
of cooled water through a series of ultra-efficient heat
exchangers, while accepting reinforcement from the
implementation of a competent water treatment program.
Such protective regimes require consistent monitoring
of the tower's recirculation flow along with a fleet of small
chemical feed pumps, which deliver timely and accurate
dosages of inhibitors, biocides and surfactants into the
hydronic stream to provide protection from corrosion,
deposition and microbiological attack. Think tiny tugboats
helping a huge ship tend the course.
The Egyptians started it all with their invention
of the "shadoof," the world's first pump, in 2000 b .c.
Over the past 4,000 years, the mechanical transfer of
liquids, gases and slurries has played an ever-increasing
role in the development of the world's vast industrialcommercial complex.
Since 1902, when Willis Carrier invented the first
electro-mechanical air conditioning unit, pumps
have been critical components in controlling the
