Baxi SB-5 Y circulating pump

The Baxi SB-5 Y circulating pump is specifically designed for recirculation systems in Sanitary Hot Water (ACS) installations, providing an efficient and reliable solution to maintain a continuous flow of hot water in residential and commercial buildings. Its submerged rotor motor ensures smooth and quiet operation, making it an ideal choice for spaces where noise must be minimized.

Manufactured with a corrosion-resistant bronze hydraulic body, this pump is designed to withstand even the most demanding conditions, such as aggressive waters with a pH below 7. Additionally, all moving parts in contact with water are made from highly corrosion-resistant materials, ensuring a long service life for the equipment. The SB-5 Y model also features an ethylene-propylene membrane, which provides additional protection against limescale deposits and ensures optimal motor operation over time.

One of the standout features of this pump is its high starting torque, which guarantees that it can start operating without difficulties, even in situations where there are temporary obstructions or when the system is cold. Furthermore, the motor is self-protected against overloads, so it does not require an additional motor guard, simplifying installation and reducing maintenance costs.

The installation of the Baxi SB-5 Y circulating pump is easy and quick, as it is designed to connect directly to the piping using fittings. This makes it suitable for both new installations and existing recirculation systems. The system also includes the possibility of rotation control and purging, facilitating air removal from the system and optimizing its performance.
