Uses and installations

The QB range is recommended for pumping clean water without abrasive particles and liquids that are chemically non-aggressive for the materials of which the pump is made. Due to their reliability, simplicity of use, and economy, they are suitable for domestic use and in particular for high-pressure applications. The pump must be installed under a vented cover and protected against exposure to rain or water spray. The QB range is manufactured with a brass insert plate to minimize the build-up of minerals and heavy metal in the volute.
