Grundfos Introduces ALPHA1
Circulator.
Grundfos Expands Energy-Efficient Circulator Line with Versatile
ALPHA1 Constant Pressure Pump. Feature-rich circulator replaces all
single-speed and 3-speed circulators in its class
Grundfos is expanding its line of energy-efficient ALPHA circulator
pumps with the variable-speed ALPHA1, which has a duty range that
can replace every single-speed and 3-speed circulator in its class.
ALPHA1 has the highest torque rating and most powerful start feature
of any comparable circulator and offers three simple-to-operate
constant-pressure modes. The LED display ensures the ALPHA1 is
delivering the optimal hydronic heating and/or hot-water
recirculation flow rate at the lowest possible energy consumption.
Because this permanent magnet motor (ECM) circulator can replace
less efficient, standard three-speed and single-speed circulator
models, distributors will be able to reduce the variety of models
stocked on their shelves and contractors will be able to reduce the
number of pumps on their truck. All components of the ALPHA1 are
produced and assembled by Grundfos in Fresno, Calif.
“This energy-efficient, variable-speed circulator is built on the
most reliable permanent magnet motor technology platform in the
industry, the Grundfos ALPHA,” says Kirk Vigil, Director of Sales
for Grundfos USA.
“Over the last decade, circulators used for hydronic and radiant
heating systems have become more energy-efficient thanks to ECM
technology, which Grundfos was the first to incorporate in a
circulator 16 years ago. ECM motors and variable-speed control allow
these circulators to drastically reduce energy consumption and
enhance system performance — proving that not all circulators are
created equal,” continues Vigil. Story continues below

Versatile Operation:
The three constant pressure control modes of the ALPHA1 are
simple to use with a single push-button control that allows
hassle-free operation for installers who can switch between
pressure modes depending on the application. ALPHA1 is
available in both cast iron and stainless steel models, as
well as standard and rotated flange pump housing
configurations. Furthermore, ALPHA1 is also available in
either line-cord or terminal box electrical connections.
Reliable, Tested Technology:
At the core of ALPHA1 is an ECM motor featuring a magnetized rotor
to avoid motor-slippage problems common to induction-type motors.
The result is a dramatically more efficient motor that generates
less heat and energy waste, while delivering a starting torque four
times higher than a standard induction motor, and stronger than any
other ECM pump in its class—a key feature should the circulator
experience long periods of idleness. In the case of a blocked rotor,
the ALPHA1’s constant restart feature attempts to restart
indefinitely every seven seconds.
Compact design = easy
installation: The sophisticated electronics of the ALPHA1 are
fully integrated within the motor, which simplifies installation in
tight spaces. The easy-to-read LED real-time display shows a flow
indicator in gallons per minute and energy consumption in Watts.
ALPHA1 offers a flow range of 0 to
19 GPM (0 to 72 Liters per minute) and a head range from 0 to 19
feet (0 to 5.8 meters). It can handle fluid temperatures from 36°F
to 230°F (2.2°C to 110°C) with a maximum working pressure of 150
pounds per square inch (psi).
Other standard features include:
- Magnetite Resistance: To prolong pump operation life, the ALPHA
series has a magnetite-resistant design with a stainless-steel
bearing plate, robust ceramic shaft and ceramic bearing rings, which
also provides for superior air venting. Magnetite, or iron-oxide
sludge, would normally hamper circulator operation as metal
components oxidize inside hydronic systems and these metal rust
particles can lead to expensive breakdowns.
- Backflow prevention: An
integrated check valve prevents backflow from occurring.
- Extremely quiet operation: The
whisper-quiet ALPHA1 uses ECM, permanent magnet motor technology and
a superior hydraulic design, allowing ALPHA1 to operate at 19.2 dB(A)
at full speed.
- Plug-and-play convenience:
Installers have the flexibility to use either a line cord or
terminal box for conduit connections.
- Multiple Configurations: ALPHA1
comes in both cast iron and stainless steel models, as well as
standard and rotated flange pump housing configurations.
- Installer-friendly pipe
connections: The circulator’s volute has a standard two-bolt flange
with a built-in, nut-capture feature that holds the bolt steady
during tightening. Spared from having to use a second wrench to keep
the bolt from slipping or turning, the installer has a free hand to
hold the circulator in place.
ALPHA1 will be available in the U.S. and Canada beginning September
1, 2017. For more information, please visit
