★Features:
GPA series circulation pump is high efficiency pump for water circulation, which features well-designed compact structure, integrated controller and frequency converter. It is easy for installation and operation in most fields of applications. In terms of electricity consumption, the unique operation mode makes Shinhoo GPA series circulation pump more energy-saving.


★Fields of applications:
1. System with constant or variable flow
2. System with variable temperature liquid
3. System with night mode
4. Air conditioning and cooling system
5. Industrial circulation system
6. Domestic hot water and drinking water supply system


★Operation conditions:
1. Power supply: voltage 220-240V, frequency 50/60Hz, single-phase AC power. According to individual voltage and frequency requirements for different applications, customized design and manufacturing is available for models listed in the catalogue.
2. Max. system pressure: 1.0MPa
3. To avoid damage to bearing caused by cavitation, inlet pressure must fulfill following requirement:
If Liquid temperature at 75℃, inlet pressure should be 0.05bar(0.5m head)
If Liquid temperature at 95℃, inlet pressure should be 0.5bar(5m head)
If Liquid temperature at 110℃, inlet pressure should be 1.08bar(10.8m head)

4. Ambient temperature: 0℃-70℃, relative humidity: ＜95%, medium temperature: 2℃-110℃. In order to avoid condensate water in stator, make sure the ambient temperature is lower than liquid temperature.
5. Medium: clean, non-corrosive, non-explosive liquid, does not contain any kinds of solid particles, fibers or mineral oil. Pump must not be used for delivering flammable liquids, such as diesel and gasoline. Delivering liquid of high viscosity will reduce performance of the pump, so while choosing a pump, the viscosity of the medium must be taken into consideration.
6. GPA series is lubricated by the pumped liquid. Do not start the pump before the system has been filled with liquid.
