The Aquatec 5800 Series Pump is ideal for drawing water from a holding tank and pressurize it, or boosting pressure from a low pressure source. These pumps can be operated either in demand mode (pressure switch controlled) or in delivery mode (controlled by external power switching device). If needed, an integral bypass can be used to limit pressure.  Benefits: Adjustable switch and bypass settings Self-priming, auto-purging Near silent operation at lower flows Highly efficient Minimal pulsations 7 year design life Runs dry without damage Features: 3-chamber construction Closed impervious diaphragm Asymmetrical manifold Integral switch or bypass Highest structural integrity Seven point clamping Engineered composite plastics Corrosion resistant metal
