The POWERBOOST PRO range is made up from two or three pumps in parallel, managed by a variable speed controller for each pump, functioning 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 this, then the control unit will start the second pump, and then the third following three pump systems. Their speed is varied 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 are terminals in the control panel for a float switch input. The float switch is fitted in the feed tank and protects the pumps from running on low level. This option is not available in single phase PRO E sets. Volt free status signals for the booster sets are available for BMS connection.
There are a number of options available to add connectivity to the system.
These include:
- A GSM dial out unit for alarm notification which is available throughout the POWERBOOST offering.
- A GPRS modem for remote access and SCADA capability. With this option it is possible to monitor the booster system performance and alarms. For system operators and service personnel this is a very efficient and useful capability. This option is only available with our PRO S offering.
