EPS Powerboost - Model Flow-V -Constant Pressure - Steadypres
The POWERBOOST Flow-V is made up from two or three pumps in parallel, managed by a variable speed controller on each pump to keep the system pressure constant and provide protection against over current and dry running. When the pressure in the system falls below the cut in set point the system will start one pump at minimum speed and gradually increase its speed to maintain the pre-set system pressure as the flow increases. If one pump is not sufficient to maintain the system pressure at the set point as the flow increases then the control unit will start the second pump and in three pump systems the third pump in turn varying their speed as required to maintain the set pressure whilst minimising energy usage and excessive pressure in the system.
As the flow decreases the system will slow down each pump in turn to maintain the pre-set pressure. As each pump reaches minimum speed it will switch off until only one pump is running, this final pump will run on for ten seconds to pressurise the vessel and ensure that the pump set does not cycle excessively.
The control unit alternates the order in which pumps start to balance the hours run on each pump. There is an input for a float switch to be installed in the feed tank and a volt free BMS connection for general alarm signals. In the event of an alarm condition the controller attempts to automatically reset after 10 minutes.
