GPA25-10IV - Variable Speed ECM Pump with PWM Control - 230V
Hydro Solar GPA IV circulator pump is the ideal choice for almost any building project – old or new. With its unrivalled energy efficiency, all-encompassing range and built-in communication capabilities, GPA IV is ideal for engineers and specifiers looking to create high-performance heating and cooling systems. The pump is maintenance-free due to the canned-rotor type design. This also means that pump and motor form an integral unit without shaft seal and with only two gaskets for sealing. The bearings are lubricated by the pumped liquid. GPA IV features PWM and 0-10V external control. GPA IV is the superior choice for a wide range of heating and cooling applications, including:
- Mixing loops
- Radiant Heating
- Radiant Cooling with Dew Point Temperature Reset
- Ground-source heat pump systems
- Air to Water Heat Pump.
GPA IV is a single-phase pump and characterized by having the controller integrated in the control box. The pump housing is available in both cast-iron and stainless-steel versions. The composite rotor can is carbon-fiber reinforced, the bearing plate and rotor cladding are made of stainless steel and the stator housing is made of aluminum. The power electronics are air-cooled. The pump speed is controlled by an integrated frequency converter. Features:
- Vast communication options, including PWM and 0-10V
- The most energy-efficient pump range within the industry
- Stainless-steel variant to accommodate domestic hot-water applications
- Auto Adapt
- Proportional-pressure control
- Constant-pressure control
- Constant-flow control
- No external motor protection required
- Innovative clamp ring with only one screw enabling easy repositioning of the pump head
- Insulating shells supplied with single-head pumps for heating systems
- Large temperature range due to air-cooled electronics.
