Baxi SB-5 Y Circulator Pump

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

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

One of the most notable features of this pump is its high starting torque, ensuring it can start operating without difficulty, 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 protector, simplifying installation and reducing maintenance costs.

The installation of the Baxi SB-5 Y circulator pump is easy and quick, as it is designed to connect directly to the pipe via fittings. This makes it suitable for both new installations and existing recirculation systems. The system also includes the option for spin control and purging, facilitating the removal of air in the system and optimising its performance.
