DESCRIPTION
The ecocirc 20-18 circulators are designed with a highly efficient
electronically commutated permanent magnet motor (ECM Technology).
Cast iron flanged models are designed for closed loop hydronic heating
and cooling systems, and stainless steel flanged and union body pumps
for plumbing systems or open loop heating and cooling systems.
