With both automatic and fixed speed options,
Grundfos ALPHA+ is suitable for all domestic heating systems. Wherever you
have previously used a UPS Selectric or Super Selectric pump, you can now
use the Grundfos ALPHA+. With all the flexibility offered by both automatic
speed and fixed speed operation, Grundfos ALPHA+ is suitable for all
domestic systems.
It can be easily installed into:
> One-pipe radiator systems
> Two-pipe radiator systems
> Underfloor heating systems
> Systems with fixed and automatic bypass
valves
> Wall hung gas boilers with low water
content
> Hot water calorifiers |

Plug-and-pump
With plug-and-pump it is no longer necessary to
open the terminal box to make electrical connections. After wiring to the
accompanying plug, simply connect it to the pump - a real advantage
especially in confined spaces. When servicing the heating system, the cable
connection to the pump can be easily removed. |
|
Power indicator
The green indicator light indicates a healthy
electrical supply. This also makes fault finding in the system easier;
opening the terminal box is not required to check the electrical supply.

Automatic de-blocking
The de-blocking function of Grundfos ALPHA+
ensures problem-free operation when the pump is used after a long period of
inactivity.
The automatic de-blocking function works through
a special sequence of 'starts' and 'stops' creating small vibrations in the
pump each time the pump starts up. The vibrations will help to dislodge
particles or contaminants that may have jammed the pump. |

Automatic or fixed speed - it's up
to you

The best in automatic and fixed speed
operation - in one pump
Grundfos ALPHA+ features both automatic and
fixed speed operation. In more than 80% of cases you will need only to leave
Grundfos ALPHA+ at its factory setting, with no further adjustments
required. This means that where you have previously used a Selectric or
Super Selectric pump, you can now use the Grundfos ALPHA+.
What does being automatic really mean?
Heat requirements vary according to the seasons,
and the time of day. As the demand for heat decreases, Grundfos ALPHA+
automatically adjusts to the actual speed and pressure to match the system
requirement. The reduces power consumption, noise, and the wear and tear on
the heating system as a whole. The pump adjusts itself as the thermostatic
radiator valves' open and close.
Silent operation
No more noise in the thermostatic radiator
valves! Unlike traditional fixed speed circulator pumps, Grundfos ALPHA+ can
be set to regulate the pressure according to the flow conditions set by the
thermostatic valves. |
