modifications − and occupy less space. For more

flo.com.

You can ensure that the electrical connections
and rotation of your pump are correct by checking

CASE STUDY: LARGE UP(S) IN THE FIELD
CONCEPT MECHANICAL • AVON, COLORADO
“Our customers want absolute, unerring reliability
and performance to match that of a finely-crafted
European car,” says Tim Rosen, P.E., one of Concept
Mechanical’s owners. “And, they don’t want to see
or hear the mechanical equipment, not even in a
garage or basement.”
To meet these needs, Concept Mechanical has
developed a hydronic recipe for demanding
clients that always includes Grundfos multi-speed
circulators.
One recent job involved the installation of an
extensive radiant heat system for a snow-melted
driveway and several of the UP(S) circulators.
“Our customers are willing to pay for good
workmanship, but they want absolutely no com-
promise,” Tim said. “Using the best equipment isn’t
necessarily a matter of choice, but of necessity. We
use the best products because our reputation, and
their peace of mind, are on the line.”
For jobs with larger loads, Concept Mechanical
selects Grundfos UP(S) pumps because of their
three-speed adaptability and remarkably quiet
operation.
They particularly like the ability to match a multi-
speed pump to its need. Grundfos’ new, expanded
line of wet rotor large UP(S) pumps have two or
three dierent performance curves and are well
suited for later system retrofits or changes.

information, and performance ranges of large UP(S) pumps.
