This Bastion Industries A Rated Central Heating Pump ZL-3002-25/6 Energy-saving 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 maximum head of 6 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 A Rated Central Heating Pump works perfectly for underfloor heating, 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 Boiler Circulating 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 of Bastion A Rated Central Heating Pump:
-
Intelligent Auto-Adaptation: The Boiler Circulating 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.
-
Ultra-Low Energy Consumption: The system incorporates a highly efficient permanent magnet motor. For example, during optimal operation, the minimum energy consumption of the pump can reach as low as 5W. Ultimately, this allows you to create highly energy-efficient plumbing systems.
-
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).
-
PWM Signal Integration: The 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.
