Electronic circulation pump GPA III 25-4-180 254180GPA3

Electronic circulation pump – an efficient solution for your installation

The electronic circulation pump GPA III 25-4-180 is a modern device designed with energy efficiency and precise adaptation to the needs of various heating and cooling systems in mind. It is ideal for both installations based on conventional energy sources and those utilizing renewable technologies. Its compact design simplifies installation, and advanced control functions ensure optimal performance and user comfort.

Construction and operating parameters

The GPA III 25-4-180 pump is equipped with high-quality components, guaranteeing reliability and long life. The electric motor's copper winding is characterized by high resistance to overheating, and the ceramic shaft and bearings ensure smooth and quiet operation. The device offers a flow rate of up to 2.8 m³/h with a maximum head of 4 meters. The use of electronic control allows for precise adjustment of operating parameters to the current needs of the installation, which translates into reduced operating costs. The G1 1/2 connection and a port spacing of 180 mm facilitate integration of the pump with the existing system.

Functionality and versatility

GPA III 25-4-180 offers as many as 11 operating modes, including automatic mode, which automatically adjusts the pump's performance to the installation's demand. Constant speed curves, proportional pressure curves, and the ability to control via an external PWM signal are also available. A multifunctional digital display allows monitoring of key pump operating parameters, such as flow rate, power consumption, and any error codes. The pump is designed to work with both water and glycol (up to 50% solution), which increases its versatility. The minimum inlet pressure depends on the liquid temperature – from 0.05 bar for temperatures up to 75°C to 1.08 bar for temperatures up to 110°C. Protection class IP44 ensures safe use in humid conditions. The set includes flat gaskets (2 pcs.) and a power cord with a length of 100 cm.
