The highly ecient dry motor design and hydraulics make
the E.2 Series circulator more ecient than other fixed speed
pumps in its class. This excellent wire-to-water eciency
leads to energy savings that building owners will appreciate.
The compact size of E.2 Series circulators makes them easy
to install, even in confined spaces. The minimized flange-to-
flange dimensions, combined with the Armstrong oering of
cross-referenced Spool Pieces, make it easy for contractors
to upgrade an existing circulator with an E.2 Series circulator,
without making changes to the installed piping.
E.2 Series circulators are permanently lubricated, so
there's no requirement for maintenance during normal
operation. When the mechanical seal wears out, it can
be replaced in less than five minutes, which reduces on-
site labor costs for contractors.
