EQ Series™ Pumps - Cheap Pool Products

EQ Series Pumps
High Performance Commercial Pumps
The EQ Series pumps deliver extraordinary
performance in every key aspect.
They’re built to last, of course, and are
also built to be incredibly efficient, quiet,
lightweight and corrosion-resistant. All
of this adds up to a pump that is highly
cost effective and suited for a wide range
of commercial water applications.
®
At the heart of the EQ’s extraordinary
performance is its unique impeller design.
It provides two significant benefits. First,
it means more efficient performance –
the EQ moves more water more quickly
than comparable pumps. And secondly,
it means the pump’s motor doesn’t have
to work as hard and, as a result, runs
cooler and lasts considerably longer.
What’s more, the Pentair EQ Pump
has been through a rigorous design,
development and testing program so
you know it’s built to handle the
toughest commercial applications for
years to come.
Available in single and three-phase
models, the EQ sets the new standard
for performance in pumps. No one else
in the industry has made a plastic
injection-molded pump with performance
like this for pool and water applications.
