UPS3 15-50/65 is a high-efficiency circulator pump designed for domestic heating systems with either variable or constant flow rate. The pump automatically controls the differential pressure by adjusting the pump performance to the actual heating demand without the use of external components. UPS3 is suitable as a universal upgrade and replacement pump. Suitable for commercial heating, domestic hot water recirculation, district heating and domestic heating.

There are three constant curves/constant speed curves, two proportional-pressure curves, two constant pressure curves and speed control via a low-voltage PWM signal profile A (the PWM signal is a method for generating an analog signal using a digital source). Other features include low EEI, deblocking device, alarm and warning indication, low noise level and very simple installation.
