Wilo-Varios PICO-STG 30/1-8-180 circulation pump with PWM signal 4232745

Wilo-Varios PICO-STG Circulation Pump – an efficient solution for your system

Wilo-Varios PICO-STG 30/1-8-180 is a maintenance-free circulation pump designed for efficient water circulation in heating, air conditioning and cooling systems. Its compact size and advanced features make it ideal for both new installations and modernization of existing ones. Equipped with PWM control, this pump offers precise performance regulation, which translates into energy savings and user comfort.

Design and application

The Wilo-Varios PICO-STG pump is characterized by a solid construction with a cast iron GG 20 (GJL-200) housing and a polypropylene (PP-GF) impeller. This ensures long-lasting and reliable operation even in difficult conditions. It is designed to operate at a medium temperature from -20°C to 110°C and ambient temperature from -10°C to 40°C. Threaded connections with a diameter of 2 inches (50 mm) facilitate installation and integration with the existing installation. Protection class IPX4D provides resistance to splashing water.

Advantages and benefits
