Description/Design
* Wet rotor circulator with EC motor
and integrated automatic capacity
adjustment
* Red button technology for very easy operation
* Graphic pump display with rotatable
display adjustable from US
units(default) to metric
* Pump communication with IF
(interface) module that can be
easily retrofitted: ideal external operation
* Motor protection with electronic
overload protection (min/max
voltage, max temp, dry run, overload)
* Interface connection for extending built
in functions, for building automation
(BA) systems and external control
* Impeller with three-dimensional
curved blades and rotor can
using carbon fibre compound
material
Equipment * Pre-selectable control modes Δp-c, Δp-v, Δp-T for optimum load adjustment * Pre-selectable speed for constant operation * Automatic setback operation for additional energy * Dual pump operation (master/slave, parallel and stand-by operation) * Programming via manual "red button" or Wilo IR (infra-red) module/monitor * Infra-red interface for wireless data exchange with IR- Module/IR-Monitor * BMS interfaces with optional IF (interface) module (LONworks and 0-10 Vdc) easily retrofitted: ideal external operation * Fault lamp and contact for collective fault signal * Pump flanges - 2 bolt oval 1 ¼" and 1 ½" – 4 bolt 2" pump flange – 4 bolt 3" 125 # raised face ANSI |
Special features/Product advantages * Energy efficiency class A * Up to 80% power saving compared with constant speed circulating pumps * Maximum efficiency thanks to ECM technology |
| Soft start high torque permanent magnet rotor • 8 Models available –interchangeable with Top S • Smart pump adjusts flow to system changes (Δp-v, Δp-c and Δp-t) • Temperature control for condensing boilers • Auto setback “fuzzy logic” • Non-volatile memory –no battery required • Standard industry flanges 1 ¼”, 1 ½”, 2” & 3” • Cataphoresis coating • Interface modules for 0-10Vdc, LON and external control • Dual pump mode (lead/lag, primary/secondary and back-up) • Infrared service/diagnostic tool available • Power consumption data logging • Ability to lock out red button • Single page start-up manual |
Yes we do have the biggest ECM pumps available, and yes we have them in AMERICA.
WILO also has larger sizes operational around the world. They are currently working on
the conversion to US standards for the even larger sizes but I have to wonder why?
We have been staging the GIGA B's giving us an even larger operational foot print to
cover even the largest system around.
With ECM we can operate at the design flow and head as well as operate down in the
heads required to utilize the super efficiency of todays boilers, chillers and systems.

You can't operate an AC motor
with a VFD down at the flow and
heads of transitional periods.
