This Bastion Industries A Rated Central Heating Pump ZL-3002-25/7.5  connects internal plumbing and heating pipework by efficiently circulating water throughout your system. Specifically, it provides a highly durable and precise transfer of heating mediums with a powerful maximum head of 7.5 meters and a nominal diameter of 25mm. Furthermore, thanks to the innovative permanent magnet motor and differential pressure controller, you significantly speed up installation by utilizing the factory-set AUTO (auto-adaptation) mode, eliminating the need for complex manual adjustments on site.

Therefore, this high-capacity A Rated Central Heating Pump works perfectly for larger underfloor heating (UFH) networks, radiator heating (dual or single pipeline), and domestic hot water systems. Additionally, it easily handles demanding applications, integrating smoothly with automated setups via its digital LV PWM (Pulse Width Modulation) signal control interface.

The pump features a robust construction alongside a convenient front-facing control panel for easy operation. Moreover, the material is highly resilient and designed to operate continuously under a maximum system pressure of 1.0 MPa (10 bar). As a result, this reliable build makes it fully dependable for long-term residential and commercial installations, capable of handling liquid temperatures ranging from +2°C to +110°C.

Key Features & Benefits Bastion A Rated Central Heating Pump :

• High-Performance Delivery: The system incorporates a highly efficient 60W permanent magnet motor capable of a 7.5-meter maximum head. For example, when you need to push water through more demanding, high-resistance heating loops, this enhanced power effectively maintains optimal flow rates. Ultimately, this allows you to create highly reliable plumbing systems.

• Intelligent Auto-Adaptation: The pump design allows for automatic performance adjustment according to the actual heat demand of the system. Consequently, you achieve optimal comfort and efficiency without needing to manually configure settings out of the box.

• Versatile Control Modes: The unit features proportional pressure (BL), constant pressure (HD), and constant speed (HS) curves. Importantly, it completely adapts to your specific needs, whether you are running a variable flow underfloor setup or a traditional fixed-speed network.

• Acoustic & Noise Reduction: The inherent design of this canned motor pump guarantees quiet operation. In particular, this internal structure provides an acoustic function, effectively maintaining a sound pressure level strictly lower than 42dB(A) even at higher flow rates.

• PWM Signal Integration: The Boiler Circulating Pump provides a PWM input and output interface for advanced external control and feedback. Besides that, this performance is fully protected by an 8mm galvanic isolation, which significantly reduces the risk of high voltage electric shock when contacting the signal cable.
