NC ACCUMULATOR PRESSURE VESSELS
Budget lower cost expansion vessels or also known as pressure vessels are to provide a reserve of pressurised water to limit the
number of on/off cycling of water booster pumps. Within the vessel is a membrane which on one side is pressurised air and the other
side is water (inside the membrane). When the pump system is started and a valve is closed water is pushed into the membrane,
reaching the set pressure by the pressure switch. The system then holds at pressure. When water is drawn the pressurised air forces
the water out until the pressure falls below the set level of the pressure switch and the pump will then re-start. All vessels are fitted
with EPDM membranes.
