Lowara Speed Booster Sets

The Lowara Varispeed booster systems are suitable for mains water supply systems in buildings and facilities.They provide constant pressure thanks to the SD60 controller, the new main board that controls the number of pumps running and the speed of each pump.

A Lowara Varispeed booster system includes pumps from the high-efficiency SV range and frequency converter in the panel. The booster set range consists of two to six SV pumps which are fitted on a common base with all components, pipes and fittings assembled.

One pressure transducer is connected on the delivery side of the set. A second one is connected but only as a reserve device. The Varispeed system ensures instant control, flexibility, efficiency and energy savings.

Thanks to its simple design and shape, the Varispeed booster systems are suitable for all types of installation where space is limited. Achieving constant pressure in the system ensures low maintenance costs, high quality operation, and cost savings.

Lowara Varispeed booster systems establish high quality, value and new technologies that work together in a highly efficient system.
