2L Constant Pressure Expansion Tank

This 2-litre expansion tank delivers constant pressure support for residential self-priming pump systems. Its internal EPDM diaphragm bladder is pre-charged and enclosed within a durable metal casing, rated for continuous operation with potable hot and cold water supplies. Intended for fixed installation downstream of the pump, it dynamically regulates system pressure by compressing air volume as water flows in, then releasing stored energy during demand lulls. Tolerances in physical dimensions fall within ±1–3 cm, aligning with standard UK plumbing practices. Functionally, the tank serves three interrelated roles: first, as a pressure buffer to suppress surges caused by fast valve closure; second, as a flow stabiliser to maintain consistent outlet pressure across varying draw-off rates; third, as a cycle reducer that extends intervals between pump activations — particularly beneficial during overnight or low-usage periods. Its design eliminates reliance on manual priming or external air charging equipment. As a dedicated constant pressure accessory, it complements rather than replaces the pump — enhancing responsiveness, quietness, and longevity. When installed with a compatible pressure switch, it forms the foundation of an intelligent domestic water management system capable of handling modern demands like power showers, washing machines, and kitchen instant-boilers without performance drop-off.
