Description
The 0011-ZF4-IFC zoning
circulator with an integral
flow check is designed to
reduce installation costs
when zoning with "00"
circulators on large
residential / light
commercial high head / medium
flow applications such as
hydronic or radiant heating,
hydro-air fan coils, indirect
water heaters or domestic
water recirculation systems,
by locating the patented IFC
inside the pump casing, a
separate in-line flow check
is eliminated, reducing
installation costs, the
reduced pressure drop of the
IFC increases the 0011 flow
performance over in-line
check valves, both the IFC
and cartridge are easily
accessed for service instead
of replacing the entire unit,
integral flow check
(IFC)patent no. 5,664,939,
prevents gravity flow,
eliminates separate in-line
flow check, reduces installed
cost, easy to service,
improved performance vs.
in-line flow checks, unique
replaceable cartridge-field
serviceable, unmatched
reliability-maintenance free,
quiet, efficient operation,
direct drive-low power
consumption, self
lubricating, no mechanical
