In addition a single Pump Node can represent up to 10 identical parallel (or series) pumps by selecting the configuration from the drop-down menu as seen here . This is a tremendous modeling time saver for handling multiple identical pumps.
The active valve can be used to model a Check Valve and a 2-way resistance (using the Bypass Line feature). Note: for KYPIPE applications a Check Valve Node (internal node) is also available.
