GPA II CV&AUTO series motor pump is mainly applied to home heating and water circulation in domestic hot water system.
The best system met GPA Series circulator pump, following:
·the constant and variable flow heat system
·the heat system of variable flow heat system
·the air-conditioning system
·the industrial circulation system
·the home heating and living water system
GPA II CV&AUTO series motor pump has the permanent magnet motor and the different pressure controller, which can continuously adjust pump performance to meet actual requirements of the system.
The control panel installed in the front of GPA II CV&AUTO series motor pump is convenient to operate for users.
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.
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.
