Premium Line pressure boosting unit, a hydrophore consisting of two or three vertical DPVME pumps. The piping system of this unit is designed to be particularly compact. Thus, the check valves are integrated into the pump and the pipes are kept as short as possible. In addition, the collection line can be mirrored when assembled on site to position the connection press or suction to the left or right of the installation. 

The installations are completely legionella-safe. The unique flow-through design completely refreshes the water in the entire system, including the switch tank and gives you complete control over the risk of Legionella aftergrowth due to stagnant water in the system. Management measures for legionella prevention and recording the number of switching/refreshment in the pressure vessel are thus unnecessary.

All Duijvelaar pressure boosting units are available upon request.
