Floor mounted cabinet enclosed single & twin pump pressurisation units for sealed heating and chilled water systems

Central Pump Supplies Ltd stock the ESPA PUMPS DUBLIN Pressurisation equipment automatically controls the pressure in a sealed system delivering water at a pre-determined pressure • Once the system has been filled the ESPRES DELUX will take over and maintain the optimum system conditions • Should a loss of water occur in the system, for any reason, the built in electronic pressure sensor will detect the drop in pressure and automatically start the pump restoring the system to the original cold fill pressure • All units incorporate dry run protection. If the supply tank should run dry the pump will automatically stop, preventing serious damage.


Set point and differential can be adjusted with an accuracy of 0.1 bar. • High pressure and Low pressure alarms can be set with an accuracy of 0.1 bar.
