Advantages
to install GPA II CV&AUTO series motor pump install and start the pump
easily.
High
comfort level
Low
noise of the pump's and the whole system's operation.
Low
power consumption
Comparing
to the traditional circulator pumps. GPA II CV&AUTO series motor
pump can consume low the power, and sticks European energy efficiency A mark
that means the lowest power consumption can reach 5W.
Circulation pump
can consume low the power, with the EEI≤0.23.
The
benchmark for most efficient circulation is EEI≤0.20.
-
Knob operation makes selection of any control mode simple
-
No external motor protection required reducing installation time
-
High-torque start improves startup under harsh conditions
-
Maintenance free and noiseless due to canned-rotor design and use of robust components
-
Fast connection plug makes electrical installation quick, safe and easy
-
Insulating shells are available to minimize heat loss in heating systems
The
pump also features two different control modes
The
pump has a ceramic shaft and radial bearings, carbon thrust bearing,
stainless-steel rotor can, bearing plate and rotor cladding, composite
impeller, all of which contribute to long life. LEDs indicate the actual operating status.
The
pump is self-venting through the system, which contributes to easy
commissioning. The compact design with integrated control box and control panel
on side of the motor fits into most common installations.
The
pump housing is made of cast iron and electro coated to improve the corrosion
resistance.
The
motor is a synchronous permanent-magnet/compact-stator motor characterized by
high efficiency.
The
pump speed is controlled by an integrated frequency converter incorporated in
the control box.
