Performance
Flow Range 0-64 U.S. GPM,
Head Range 0-38 Feet
In a pressure system, the required inlet pressure is
the allowable system pressure.
In a system open to the atmosphere, the required
inlet pressure is the minimum distance the pump
must be located below the lowest possible water
level of the water source (tank, pool, etc.).
Miximizer - Mixing Reset pump
The Grundfos MixiMizer, a fully integrated injection
pump and indoor/outdoor controller, is the only
pump and controller system of its kind.
Equipped with a weather responsive control, also
known as indoor/outdoor control or reset control,
the MixiMizer automatically calculates and controls
mixed water temperatures according to outdoor
temperatures in primary/secondary piping systems.
The control also provides pump exercising for 10
seconds every 3 days and a 20 second post purge
when the heat demand is removed.
For maximum design flexibility, the MixiMizer can
be integrated into a thermostat or zoning control
system through the user selectable ‘external call for
heat/demand input’.
A fully serviceable check valve integrated into the
pump housing eliminates ghost flows in
primary/secondary injection systems and zone
applications.
LEDs located on the terminal box are designed to
indicate performance and diagnose faults without
tools.
Other standard user selectable features include
boiler protection, system/slab ‘over temperature’
control and a 5 degree F parallel shift of the heating
curve
Variable Speed pump
The Grundfos Variable Speed pump is another
product with fully integrated control. The variable
speed controller requires a control signal from a 0-
10/2-10 DC voltage sources or 0-20/4-20 mA
current sources and is user selectable.
If desired the manual-% dial allows the speed of the
pump to be manually adjusted and set by the user.
The speed of the pump may be manually adjusted
anywhere from min to 100%, but once set remains
fixed at that speed.
In addition pump speed may be set as 0-100% or
15-100% by user.
The control also provides pump exercising for 10
seconds every 3 days and a power up reset, which
runs the pump for 3 seconds at full speed, for all
modes of operation.
Terminal box mounted LEDs provide operation
(power is applied) and performance (flashes slower
or faster) indication.
